Why a Technical Mujahidin Magazine?
The Technical Mujahid magazine provides everything that benefits the mujahidin in the media sphere on the one
hand and visitors to jihadist websites on the other. The magazine follows up everything that is new and useful in the
field of information security, ways of protecting computers, editing, sound engineering, the news of the jihadist
media, and monitoring the Crusader leaders' comments about the impact that the jihadist media have on them, etc.
We seek to attain the following objectives by publishing this magazine:
1. To remove the fear and panic complex from the hearts of some people who are held back from actively
participating in jihad because they think that intelligence services are watching their every move and
counting their every breath. When they are better informed of the facts, they will know when to go forward
and when to hold back.
2. To disseminate a sense of security in a scientific way among the members of the jihadist websites as a
precaution that we are required to take in a logical, organized, and realistic way with neither exaggeration
nor disregard.
3. To spread technical awareness of everything that might be useful in the jihadist media sphere including
visual editing, sound engineering, and other basic media skills.
4. To publish scientific articles about some modern techniques that can help to develop the work of the
brother mujahidin who operate in the field.

household, and all his companions.
We return to you in this issue of our blessed magazine, with the power of God.
At the beginning we would like to thank and appreciate the efforts of all the brothers who encouraged and supported
us and were generous in providing us with their views, observations, and questions about the magazine and its first
issue.
While offering thanks, we should not forget to mention our brothers who responded to our call and sent us technical
articles to publish in the magazine. We tell them that this time neither time nor space allowed us to include all the
articles that were sent to us. We promise that your articles will appear in future issues, God willing. We seize this
opportunity to encourage other brothers to begin doing creative work and to send us their articles or suggestions.
We should also mention that we could not respond to all the brothers who sent us proposals or requests but we
would like to tell them that all that they wrote will be taken into account, God willing.
Regarding this issue, we will present in it various subjects, beginning with video and editing issues in view of the
fact that they are important to jihadist media work. This issue also contains important articles on protecting
information either by putting it in code or hiding it inside electronic images. We have decided in this issue to begin a
series that will explain the steps involved in establishing a hosting company and creating websites for jihadist
purposes.
We will continue our war against the enemies of God in every land and under every sky until all Muslim lands are
liberated from the desecration of the aggressor Jews and grudge-bearing Crusaders and until all religion is devoted
to God and we can see the banner of Islam fluttering over the land.
God is great. Dignity is to God, His messenger, and the believers.
We will be happy to receive your questions and letters sent to the magazine's domain:

Secret Communications: Hiding Secrets Inside Images
by Abu-Mus'ab al-Jaza'iri
The thing that worries the Federal Bureau of Investigation
most is when the mujahidin use the secret
communications technology known as the art of hiding
messages.
This art, known as steganography or information hiding,
is the most sophisticated method of sending information
either via the Internet, a cellular telephone, or other
information-transmitting tools.
Although sending coded messages by using the public key
algorithm, which can be deciphered if you know the key,
guarantees the confidentiality of a particular piece of
information or private communication, it still has a point
of weakness because the opponent is aware that you are sending coded messages. This in itself puts the sender in
some sort of danger and causes many intelligence agencies to discover the source of the messages and place the
sender under surveillance. This is where the art of hiding information comes in. It abolishes the weak point of coded
messages by hiding information of all types inside other types of expression like graphics or musical notes for
example.
The following study will acquaint the reader with information hiding technology and the parallel technology of
uncovering the secret information, which is known as steganalysis. We will also warn the readers against certain
types of programs that claim to be able to hide information. Actually they are fraudulent programs that no one
should use. They can cause tremendous damage because while you might think that you have hidden the information
you are sending, someone familiar with the program can extract the information you have sent with extreme ease.
With the spread of new media technologies in the 1990s attention began to be focused on hiding information inside
the digital media. Prior to this development, watermarking was used to protect copyrights such as protecting a
photographer's copyright by watermarking his photographs. The real objective is to send secret messages under the
cover of digital tools that arouse no suspicion. This helps to prevent their interception or even the knowledge that
messages are being sent.
Interest in hiding information grew among people doing research into signals and digital pictures as useful tools of
information security. Many countries began to feel worried that this new technology would be used to send
information that could undermine their public security and interests.
[pg 2]
So a new sphere of technical methods came into existence, namely, methods that could uncover the existence of
hidden information with the aid of digital tools. This new field has been given the name steganalysis.
Steganalysis is more successful when the information hiding technology is weak. Although steganalysis can uncover
some digital signals carrying hidden messages, it frequently fails to do so when the hiding methods are
sophisticated, especially as hundreds of millions of digital signals are continuously traveling across the Internet. It is
impossible to analyze this astronomical number of signals.

Diagram 2 [Diagram 1 is missing as received]: Color picture with images of the basic colors composing it. The basic
picture is a grayscale conglomeration of 256 color shades for each scale, which when merged produce the color
picture.
1. New Technologies and a Long History
The hiding of information has historically been linked with spying on the enemy and attempting to send secret
information without being discovered. Secret ink was one of those information hiding methods. In ancient times
onion juice was used to manufacture this ink but in the 1950s and 1960s chemical engineers developed new methods
of writing between the lines. The spy would pen an ordinary letter to a friend but would use the secret ink to include
secret information.
[pg 3]
The visible message is the medium while the real letter is what the ordinary reader cannot see. The secret text is
made visible by wiping the page of the letter with a special chemical that reacts with the secret ink.
Perhaps many people remember the story of the Egyptian intelligence operative Rif'at al-Jamman (Ra'fat al-Hajjan)
who was recruited by Egyptian intelligence and planted as a Jewish young man inside the Zionist entity in occupied
Palestine. He was trained from the start to send secret messages by writing letters to his girlfriend in Paris. This
girlfriend was actually an apartment rented by Egyptian intelligence in the French capital. With the development of
communication engineering Al-Jamman was trained to send and receive coded messages by radio using the Morse
code, a language invented by the scientist Morse in 1890. It relies on identifying letters by using dots and dashes
only. This later came to be known as binary encoding in digital communication.
2. Information Hiding
While the use of codes protects information secrecy and prevents ordinary people from understanding the contents
of messages, steganography goes further. It hides the fact that information is being sent at all. The use of codes
sends secret information but does not mind that others realize that secret messages are being sent. Steganography's
function, on the other hand, is to send information without letting anyone realize that communications are taking
place. It sends information inside various signals using highly secure codes that use deciphering keys varying in
strength from 256 to 2048 bits.
The function of information hiding is to relay secret information without arousing the slightest suspicion that
messages are being exchanged. This is done under the cover of digital signals that look totally innocent. Pictures are
the most widely used medium to relay secret messages. Images of the non-compressed bitmap type and compressed
jpeg files have been used. The information is hidden inside the color images relying on several methods including
modifying the bit. Other methods use the frequency domain.

2. (1) Modifying the Bit (LSB Modification)
In this technical method the bit inside the picture's color component (pixel) is modified. It is the smallest bit in the
color and when it is modified, this does not alter the shape of the picture at all because it represents only one part in
255 parts of the basic color. The basic colors in digital images are red, green, and blue. This means that we can
exploit three bits out of every 24-bit component in a picture.
Modifying the smallest bit in the color introduces a type of noise into the image that is measured by the signal to
noise ratio and is referred to by the letters SNR. In this case the ratio is 50 decibel-dB, which means that the
alteration to the picture cannot be noticed.
To calculate the quantity of material that one can hide inside a picture, we carry out the following operation:
q=.3((L x w)/8)
[pg 4]
The symbols refer to the following:
q: the quantity of material introduced into the image
L: is the length of the image (that carries the hidden message)
W: is the width of image
Keep in mind that this is the quantity of material that can be hidden in the image without compression. If the
material is in compressed form, a much larger message can be hidden. This means that we can hide a noncompressed
message consisting of 300 letters in a picture that is 800 pixel wide and 1 pixel high. Such a picture
passes unnoticed on any website and can be part of the site's design. It will never arouse any suspicions. If we
compress the message, we can send a message that is several times longer.
Among the well-known programs used to merge messages into images in this way are: EzStego, S-Tools, and Hide
and Seek. There are others. We must distinguish between hiding information in images that cannot be compressed
and hiding it in images that can be compressed. Compression alters the color values and the picture quality.
Diagram 3: The three layers that form color pictures. Illustration of the least significant bit (LSB) in each basic
color. Every basic color is composed of eight bits. Three bits are introduced into each pixel.
The term pix represents the image component and LSB represents the bit. Color images are made up of three layers,
namely, the basic colors of red, green, and blue. Each color consists of eight bits and can represent 256 shades of the
basic color. This means that every color in a picture that consists of 24 bits can represent 16,777,216 shades.
[pg 5]

Three bits of every image component are used to merge and hide a secret message, keeping in mind that merging
this information does not affect the size or quality of the picture. It will continue to look as it originally did.
Additionally this technology does not signify real information hiding, as we shall see later when we look at some
programs that are marketed as information hiding programs but are something completely different. The information
hidden in them can be discovered and retrieved with total ease.
3. Digital Fingerprint
The digital fingerprint consists of a cipher that ranges in length between 218-512 bits. It is used to ensure that a
certain file is the original one and not one that has been altered. The digital fingerprint is also used to preserve a
password inside a file. The technology involved in a digital fingerprint is based on a one way encryption. This
means that it is not possible to retrieve the password from the digital fingerprint. This is known as Hash or Message
Digest.
Diagram 4: Program to calculate the digital fingerprint of texts or files. The fingerprint is a one way encryption.
4. Deciphering Hidden Information or Counter Solutions (Steganalysis)
Deciphering hidden messages is a task that is contrary to hiding information. The function of steganalysis is to
reveal whether a particular graphic file, audio file, or other type of file contains hidden information. The deciphering
process depends on the type of file used to carry the secret message. If a certain image is suspected, digital image
technology is used to decipher the LSB layers.
[pg 6]
A color image contains 24 bits, only 3 of which can be suspected of hiding information. These three bits are then
extracted and examined to see if there are disparities from the perspective of statistical analysis in the whole expanse
of the picture. This technology fails entirely if the information was put in cipher before it was merged and
distributed in an appropriate way inside the image.
It is easy to uncover hidden information in JPG images because the colors are linked together by the DCT system
(Discrete Cosine Transform). Any alteration of the colors resulting from hiding information in such an image causes
defects in the DCT coefficients, thus making it easy to realize that a secret message has been hidden inside even if
this message is not extracted. To reduce the chances of uncovering such messages, some programs exploit a smaller
number of color layers, as for example hiding the message inside the color red only.
Some programs are sold over the Internet on the grounds that they are programs in which you can hide information
but in reality they serve no such purpose at all. They merely rely on manipulating the identification of the file's
beginning and end. In this study we will present the most recent such program, which is called Steganography 1.8
and we will show how simple it is to extract the hidden information from it with extreme ease. This renders their
claim about putting messages in code and hiding them completely meaningless.

After opening the carrier file with a hexadecimal program, one can go to the end of the file where the cipher for the
end of the EOF file is found. In hexadecimal language the number is 454F46. The original file in this case is called
Cellphones.pdf.
Diagram 5: A steganography program: Attractive but fraudulent
[pg 7]
Diagram 4 [as published]: Details of carrier file showing the end of file marker (EOF)
After using the Steganography 1.8 file, we will notice that the program did not merge the second file into the first
file but merely attached it to the end of the first file in a process called concatenation.
The following image shows how this attachment is done. The information of the carrier file is shown in yellow and
under it appears the file that the program has hidden. In (Diagram 7) the same file has been hidden and protected by
a password. When you compare the information in Diagram 6 with Diagram 7, you will realize that the password
has no connection at all with putting the password in code. The information in both diagrams is identical regardless
of the password. This simply means that the program does not put the information in code by relying on the
password.

Diagram 6: Hiding a file without using a password
[pg 8]
Diagram 7: Hiding a file and protecting it using a password
4. 1 Revealing What Is Hidden
We made several experiments to hide various files inside various types of original files. After using a hexadecimal
editor to open a file that hides another file inside it and going to the end of the file, we noticed that 64 bits are
repeated in all the files in two sections (48491200 and 0084E673), shown in blue in the diagram. These 64 bits are
considered a telltale sign of files that hide other files inside them. This means that they reveal that there is a hidden
file inside the original file.
4. 2 Putting the Password or the Message in Code
We carried out an experiment to hide a file inside another file. The first time we did not use any password and the
second time we did. Our aim was to discover whether the program put the information hidden inside in code or not.
We got a surprise!
In Diagrams 8 and 9 there is no difference in the two pictures under the command line although the first picture
represents the hidden file that has not been put in code (without a password). The second picture represents the
hidden file that is protected by a password. Of course there is no difference and this means that no cipher is used in
hiding the information. What the program does is save the digital fingerprint of the password alone and rely on a
message digest made up of 128 bits (16 x 8 bits).

After comparing the file for which we used a password with the file without a password, we discovered the place
where the digital fingerprint of the password was saved, namely, 128 bits directly before the cipher: 0084E673.
When you use a password, what the program does is to calculate the digital fingerprint of the password and save it
inside the file. This method of protecting hidden information is not worthy of the name because it is so easily
uncovered. It has also been discovered that without using a password, the following fingerprint is found instead of
the digital fingerprint of the password. The presence of this fingerprint means the file is not using protection for the
hidden information. The special fingerprint is:
6C 3C 39 6C 30 6B 6C 31 30 6E 38 38 6A 3A 38 3C
[pg 9]
To abolish any password that protects the hidden file, whenever any other fingerprint is present, it is enough to
delete it and replace it with this special fingerprint that is characteristic of a hexadecimal editor. This way we can
retrieve the hidden file with extreme ease without even having to know what kind of coding was used in producing
the digital fingerprint of the password. What we would simply be doing is abolishing what the manufacturer
describes as coding. It is merely a deceptive device built into the program.
Diagram 8: Showing the end of the carrier file after hiding another file inside of it without using a password
Diagram 9: Showing the same operation in the diagram above, but this time using a password
4. 3 Retrieving the Hidden Information in Three Steps
[pg 10]

The following three steps are used to uncover and retrieve any file that has been hidden inside another file:
1. Search for the fingerprint 48491200 with 0084E673 at the end of the file. If this is found in the file, it
means that it contains another hidden file inside it. This first step rebuts the program's claim of successful
information hiding.
2. Replace the password's digital fingerprint which consists of 128 bits and appears directly before the cipher
0084E673 and replace it with the special fingerprint: 6C 3C 39 6C 30 6B 6C 31 30 6E 38 38 6A 3A 38 3C,
which deletes the password. This second step rebuts the program's claim that it can protect information
when a password is used.
3. Open the carrier program and retrieve the hidden file. This last step shows you that what you imagined was
a coded and well hidden message was merely an illusion. It can be easily retrieved.
At this point we can respond to the manufacturer's claim that appears on the program:
Make your secrets invisible in just 3 easy steps! [English in original]
This is our answer: Your hidden secrets were retrieved by three easy steps regardless of the code you used in this
program.
5. Real Information Hiding
In real information hiding technology, the carrier file, either an image or an audio file, can carry a specific quantity
of information without any alteration to the file size or the picture and sound quality. When you put your
information in code before hiding it, you can guarantee its total secrecy. This can foil steganalysis that relies on
visual or statistical analysis of the messages haphazardly merged with the color layers that are used in the hiding
process. By additionally using compressed files, it is possible to increase the size of the statements or messages that
you wish to hide. The following example illustrates the quantity of information that one can hide inside a picture for
example. Keep in mind that the following program is not widely known and the techniques that it uses have not been
published.
[pg 11]

Example 1: The picture above, 512 x 380 pixels in size, hides inside it 200 pages of the holy Koran. These pages,
together with the inflections, represent more than 240,000 characters including spaces and line returns. The code
used is 1024 bits and the compression ratio is 330%. The hiding of all this material does not increase the original
picture's size by even 1 bit. One cannot distinguish between the original picture and the picture that hides
information inside it.
It is possible for a picture that is 700 x 800 pixels to hide the entire Koran inside it together with inflexions, page
numbers, and verse numbers. Images like this one are able to hide not only text material but also all kinds of files.
You can, for example hide a computer program, an audio file, or an image, or collect several files in one compressed
file and hide it in the picture, all this without increasing the picture's original size.
Example 2: The small picture above, which is 50 x 100 pixels hides 20 communiqués by the Islamic Army of Iraq,
namely, more than 15,000 characters including spaces at a compression ratio of 1000%. This high level of
compression can be obtained by what is called data redundancy.
[pg 12]
This involves the fact that all mujahidin communiqué have the same preamble and the same ending with only the
body of the communiqué changing each time. This structure allows the program to increase the compression. These
small pictures, which can hide a large quantity of messages, can be transmitted by using cellular telephones within
multimedia messages (MMS).
Example 3: A picture that is 500 x 3 pixels only, so that it might not be noticed, can be part of a website design. Yet
it can hide a message that has more characters than the Koran's opening sura [chapter].
Diagram 10: A histogram of an original picture and of the same picture after more than 240,000 characters have
been hidden inside it (example 1). The slight change does not affect the picture's clarity or arouse any suspicion
because the color distribution appears normal.
6. Way of Selecting Carrier Images
Choosing the picture in which the information or messages will be hidden is subjected to a prior analysis of the type
of image. To ensure a high hiding capability, we conduct a steganalysis examination of the picture before using it.
We will give here three examples of how to choose suitable pictures.

A distinction must be made between graphics and photographs. The first kind contains a limited number of colors
and lower color layers that are not all subjected to haphazard distribution. This makes the task of hiding information
inside such an image impossible because of the ease with which the hidden material can be detected.
[pg 13]
However, discovering that information is hidden inside the graphic does not mean that the discoverer can learn the
contents of the message because he does not know the code, the compression level, or the method of hiding. For this
reason we should not use Western programs because they are purely deceptive. Each one of them has a type of
signature indicating that the carrier file (image) has been amended by a certain program.
6.1 Steganalysis Using Visual and Statistical Analysis
6.1.1 Steganalysis Using Visual Analysis, Example 1
Diagram 11:
Part 1: The original picture
Part 2: The picture after hiding information inside it
Part 3: Layer analysis of the original picture
Part 4: Layer analysis of the picture that hides information inside it. It shows a rectangle
containing haphazard colors that indicate the presence of a secret message. After obtaining this
result, the role of steganalysis ends. The result means that this picture is not suitable for use as a
medium file to carry hidden information.
Diagram 11: Pictures (drawings) containing a limited number of colors. The hidden message within is easily
revealed because of the homogenous background without the ability to know the content.
[pg 14]
6.1.2 Steganalysis Using Visual Analysis, Example 2
Diagram 12:
Part 1: The original picture
Part 2: The picture with a secret message hidden inside it
Part 3: Layer analysis of the original picture
Part 4: Layer analysis of the picture carrying a hidden message. A rectangle of haphazard colors
appears at the top of the picture, indicating the presence of a secret message.
Part 5: The position of the message inside the picture has been moved to the lower part where
there are haphazard colors. In this case visual analysis becomes incapable of detecting whether
there is hidden information or not.

Part 6: The same picture but after we placed a red rectangle over the secret message to show its
position.
Diagram 12: Shows a type of drawing that can be used to hide messages, but the location of hiding should be
carefully chosen. Placing the message in the green area, which is revealed through enhanced LSB layers analysis by
the color black, makes it easy to discover.
[pg 15]
6.1.3: Steganalysis Using Visual Analysis, Example 3
Diagram 13:
Part 1: The original picture
Part 2: The picture after hiding a message consisting of 16,000 characters in it at a tenfold
compression rate. The message occupies only 9 percent of the area of the picture that measures
250 x 190 pixels.
Part 3: Layer analysis of the original picture
Part 4: Layer analysis of the picture hiding the secret message. Of course no differences can be
detected between the two pictures by using visual layer analysis. Even when other analysis
techniques are used, it cannot be definitely known that there is anything hidden in such pictures.
Even if a particular program claims that they contain something, this is merely a possibility that
might be right or wrong. The type of program that tries to uncover secret messages by relying on
the theory of likelihood errs also when normal pictures are used, thus making their user lose
confidence in their usefulness. Erroneous discovery of hidden information is called false positive.

Diagram 13: Layer analysis shows that the picture above has a wide range of colors. Messages are hidden inside it
but visual layer analysis techniques cannot discover such messages. This is a specimen of the images that must be
used.
[pg 16]
Diagram 14: An example showing the failure of statistical analysis in identifying the image that hides 1.6 kb of
coded information. Upper picture: Analysis of the picture without information. Lower picture: Analysis of the
picture with hidden information. The analysis shows that the two pictures contain information, thus making the
analysis lose credibility.

Diagram 15: Statistical analysis completely fails to discover the presence of secret information. The red line at level
zero shows that the three pictures, which were statistically analyzed, do not contain any hidden information. In
reality, however, two of the three pictures above contain 1.6 kb of coded information (the analysis pertains to
Diagram 12)
[pg 17]
7. Conclusion
The battle between steganography and steganalysis continues and represents the cornerstone in the battle of
transmitting secret information. The first aspect of this battle represents secret communications where information
and statements are transmitted without letting anyone be aware that communications are taking place. The other
aspect represents the attempt to stop this type of communication. Several programs are used in steganography and
most of them have counter programs that can reveal the likely presence of secret messages.
In numerous cases, as in the program that we analyzed, some programs' claim to hide information successfully is a
pure lie and deception. We showed how it is possible to retrieve the information that was hidden and protected by a
password. This should alert us not to use any program without carrying out prior analysis of it.
A sophisticated steganography program merges several advanced techniques together to perform the task with high
efficiency. The program compresses the information at high rates and then puts it in code at 2048 bits prior to hiding
it. Some programs hide brief messages inside brief audio files. Some programs use a limited number of basic color
layers to try to evade any likely discovery through the use of steganalysis, which relies on the statistical distribution
of colors.
Other programs hide statements or messages by using the most sophisticated communication engineering techniques
in a process described as spread spectrum. This is done to escape all possible steganalysis processes. We also
showed how to select suitable photographic pictures or pictures of natural scenes because visual analysis and
statistical analysis fail to discover the secret messages hidden inside them. This makes the art of hiding information
a science worthy of its name and is unique in transmitting secret information without being detected.

How To Set Up a Jihadist Website from A to Z (Part 1)
by Abu-Dajanah al-Makki
May God, the Lord of the worlds, be praised. Peace
be upon the most virtuous of prophets and
messengers, our master Muhammad, his virtuous and
pious companions, and all those who emulate them
down the ages until Judgment Day.
We will now begin, with the aid and power of God, to
explain to the brothers who support jihad the way of
establishing jihadist websites to propagate the
mujahidin's ideology and publish the news of their
operations to inform the world of the truth about the
mujahidin, their operations, and their goals.
This study will consist of several subjects. In this
subject we will explain in a very simple way, the
basic steps of finding the best possible hosting
company. We will then speak about various types of
domains, how to reserve space for them, and related
issues.
1. Website Components (What a Website Is)
A website is composed of two parts:
1. Website space: This is the space in which you post your files and pages. It is actually your website and is
rented from a hosting company.
2. Website domain: This is the name that you use to deal with your visitors. It is your hosting address. The
Internet is like a large city and when you reserve space for yourself, you will be found on the net but you
will need an address, which is referred to as a domain, where your visitors can access your website.
[pg 20]
2. Plans To Rent Space for a Website
Some companies offer space for websites free of charge but these companies cannot be trusted with your files. They
frequently disappear in mysterious circumstances and have their own motives, like putting advertisements on your
pages, and they do not commit themselves to anything with regard to you. We will not talk about such companies
but about the hosting companies that charge you for renting space.
2.1 Important Advice
1. Deal with the foreigner (though we regret this necessity): There are many hosting companies of various
nationalities. There are Arab and other companies. There are problems characteristic of Arab hosting
companies that are managed by one person who will not be totally committed to you. They offer you
expensive plans but meager advantages. Frequently they deal horribly with their customers and will bargain
with you over your files or even databases.
2. Ask about a hosting company's reputation and its clients: Do not rent space from a newly created company
or even one that is a year old. Do not rent from companies that hassle their clients. You can discover who
the clients are by various means. You can also make inquiries about the company's own technical support
capabilities. Always rent from reliable companies and examine the speed with which they load and
respond.
3. Make sure about the quality of the hosting company's technical support: Technical support is an important
thing that you might need. The website might freeze. You might face other problems. In this case it is the
technical support that will help you and answer your questions and requests. Is the technical support unit
alert? Is it cooperative enough for your purposes? You know your website and what it will need.

4. Things that your website will need: Sometimes some brothers need to create a website for a particular
purpose or their website requires special features. For example you wish to create a website and want to
install a script that relies on the indicator COPY. You should ask the company's technical support about this
indicator. Some of them de-activate it. You might want to send out a mailing list that relies on MAIL.
Some of them close it. Make sure you ask about it. You might need a closed safe mode and so on. There are
other tools that you know that you will need. They might not be active.
5. Type of server and number of sites that it supports: You might need to know the type of server and how
many websites it supports. The type and speed of server will affect the speed of your own site. The server is
a computer and like any other computer, you can ask about its specifications and the number of sites that it
supports. This might affect your own speed.
6. Period when server is up: The server might stop for a few moments and then come back. There are ways of
monitoring this. The time when the server is up and connected to the websites that it serves is given a
percentage like 99.8 percent. This is called Up Time.

2.2 Different Hosting Advantages and Plans
You need space to insert your files, post your pages, and operate your programs, like forums for example. You need
methods of creating programs. What do these terms mean? How does a hosting company make its plans?
1. Space: Hosting companies offer spaces in gigabytes or megabytes that they call storage space. This space is
important for you to place your files. Will your files be a few simple pages that require little space? Or will
you also post audio and video files? Will you place the files in the website or in several hyperlink sites?
2. Exchanging data: The data space is the space in which you can post your material. Everything you post will
be measured and you are usually allowed to post a limited amount of data, which is counted by the month.
Sometimes the companies set daily conditions. Let us suppose that you have a 100-Mb file and the space
you have is 10 Gb. This means if this file is accessed 100 times, your website will be suspended until the
end of the month. The pages do not use up a large space but this depends on the number of visitors to the
site. Data space is calculated in gigabytes and called Bandwidth Transfer.
3. Huge and unrealistic plans: Sometimes you come across huge offers like 300 Gb at a low cost. This is
called oversell. This means that the hosting company is selling space that it does not really possess but
knows that no one is using this space at that time because 90 percent of website owners do not use up more
than 10 percent of their shares. Your website will not need all this space because if it does, this means that
it will be using a lot of the CPU-RAM resources. This can result in the suspension of your website. This is
where it becomes important to ask the company's clients and people with expertise about the actual space
that your website will need and whether this will use up too much CPU-RAM. Using so much CPU-RAM
resources might force you to look for a private server or a semi-private server, VPS.
4. Databases: You will need databases for many of your website programs. You might need more than one.
You could, if you wanted, place more than one program on the same database but this is not advisable.
There is more than one type of database. You might need a particular type. Ask for it. The generally used
type is MySQL. Some websites limit the size of a database, which might be less than 50 Mb. Now
databases use up space but sometimes no limits are placed on their size.
5. Electronic mail: You will need email capability for the exchange of messages. This will be your official
email. Limits might be set on the number of emails allowed or the space available for them. Again it might
be unlimited.
6. PHP Support: This is support for the programming language. It is a very important language on which most
websites operate. It is supposed to be present in all space sold by the hosting companies. It might not be
mentioned because its presence is taken for granted. The existence of databases, however, is proof of its
presence.
[pg 22]
One must make sure that the PHP is present. Many programs depend on PHP4. Will the server support
PHP4 or PHP5? Which one will you need? You might need PHP5 instead of PHP4.
7. Perl Support: This is usually used in advanced applications and you might not need it at this stage.
8. CGI Support: It is an important programming language and you might need it for various programs. It is
widely used and it is advisable to get it.

9. Control panel: There are various types of control panels. A control panel makes it easy for you to control
and manage your website and establish databases, manage your email, and manage your files. There are
famous and useful control panels known as CPanel.
10. SSL: These are the coded links known as https. They have their own prices, licenses, and IPs. They might
be offered free of charge or you might need to pay for them.
11. Preparation fees: You might find out that you have to pay preparation fees for one time only, especially if
you rent space for a brief period only. You are charged this fee to ensure that you are serious. Usually you
do not have to pay, however.
12. Parked domains: This involves adding more than one domain to your website. If you have more than one
domain for the same site, then you will need this option.
13. Add-on domains: If you want to have more than one website in your rented space, you will need this
option. You will have more than one domain that visitors can access. This can be done by creating a file
and linking it to the first domain. The add-on domains might be limited to a specific number or they might
be unlimited.
14. Additional programs: There are additional programs that can be added to your control panel and be useful
to you, as for example Fantastico.
15. Free add-ons: Sometimes there might be free add-ons, including a free domain, an SSL, or a private IP, or
you might be given those for an additional period free of charge.
16. Server operating system: The server operating system has an effect on your operations. This includes Lynx
servers that use PHP as a programming language and MySQL as databases, and Windows servers that use
ASP as a programming language and Access and MSSQL databases. Prices are different for each.
Windows servers are more expensive not because they are better but because Windows requires a license
that the companies pay fees to purchase. Generally, however, Lynx servers are the best and most famous.
17. Refund guarantee: Large companies might give you a refund option after a trial period. This is usually done
after 30 days or as the hosting company specifies. It is called money back guarantee.
3. Domains
The domain is very important to you. It sticks to the visitor's mind and identifies you and your website. It stays with
you more than the hosting space itself. You might leave the hosting company at any time but you will not leave the
domain. When you change your hosting company, you will not lose your visitors or reputation, unlike when you
change the domain. Since matters are such, you must choose your domain carefully.
[pg 23]
3. 1 Important Advice
1. Search for the largest companies: There are small companies that are licensed to act as representatives of
larger companies. Do not purchase space from these. Go to the original company. Be with the larger
enterprises.
2. Do not place all your eggs in one basket: If possible do not reserve a domain from the hosting company or
let the hosting company pick a domain for you from just any source without giving you a control panel for
your domain. You need to have a control panel for your domain. Some cunning hosting companies do not
give their customers a control panel for the domain at first and later charge them a high price to provide
them with one. If you are suspended by your hosting company, you can do business with another. You
cannot do this with the domain.
3. Ask about a company's reputation and its clients: Do not reserve a site from a new company or even a
company that is one year old. Do not deal with a company that does not treat its clients well. There are
well-known global companies that have a stellar reputation.
4. Special features: You might need special features for your domain. You own a server and you want a NIM
server. Will the company easily provide you with this? If you wish to hide your information, will the
company provide you with this capability at a reasonable price?
5. Do not worry if the domain is not immediately present: After you reserve a domain, you might not find it
on the web after connecting it to the hosting company. Do not be surprised. Minutes, even hours might pass
until the communications companies connect the domain to your space. This depends on your Internet
provider. If you reserve a site with proxy, you might find it immediately present but if you do so through a
slow Arab provider, you might have to wait for hours or even a whole day before it appears. Do not worry.

6. Express yourself through the domain: Choose an expressive name for your domain. If the website is called
Al-Ikhlas, let the domain be Al-Ikhlas in Latin characters. Attach a suitable extension although visitors
generally look for the .com extension because it is the most widely used.
7. Check name accuracy: Make sure that the domain can be easily memorized and spelled correctly if it is in
Latin characters. If it is Arabic written in Latin characters, make sure that it is simple. Test it first with
some brothers.
8. Close the domain: On your control panel you have the option of closing the domain. This option serves to
prevent the transfer of your domain from one company to another. You need this option.
3. 2 Specifications and Various Terms Used in Domains
1. Different names: Domains have various names, each denoting something like a country's name or the type
of website and its focus. The names vary in price also. Some are cheaper than others like the extension
.info. Some are pricey like the extension .tv. The simplest and most widely used is .com.
2. Special offers: While reserving your website, you will come across special offers for domain or hosting
features that might be useful to you. You might find some features highlighted and you can delete them if
you do not need them.
[pg 24]
3. Registration privacy: A domain might have a collection of data that is offered to the public or to those who
look for them, including a name, an IP address, and email. You choose these and they are different from the
data you buy. You can insert false information of course. You can also purchase a private registration
service so that no information will be supplied about you. You might have to pay for this service or it might
be free.
4. Renewal fees: Sometimes tricks are used, like making the domain price cheap but the renewal fee
expensive after a year. The first price is to attract customers and the second high fee is to make up for the
initial cheap price. Do not be deceived by the cheap initial price. Check the renewal fees first.
5. SSL certificate: This is a certificate to guarantee SSL (Secure Sockets Layer). This has an additional price
and it comes as 128 or 256 bits.
3.3 Connecting the Domain to the Hosting Company
"To connect the domain to the hosting company, you need to work from two angles: from the domain angle to
inform it of the server that contains your website and from the hosting company's angle to inform it of your domain.
"On the domain's control panel you will find the Name Server option. You can use this option to alter your website
name, which usually consists of two or more addresses in this fashion:
"NS1.host.com//NS2.host.com

4. Conclusion
In the foregoing article we explained the initial basic steps to establish a jihadist website on the Internet. After
selecting a hosting company, a hosting plan, and a domain, the website will be established. In future articles we will
explain how to manage the website and upload material on it until we end up with a complete jihadist site, God
willing.

Smart Weapons: Short-Range Surface-to-Air Missiles (Part 1)
by Abu-al-Harith al-Dulaymi
Surface-to-air or antiaircraft missiles are divided into
three classes: short-, intermediate-, and long-range
missiles. The second and third types are fired from huge
launching platforms and have ranges of 200 km or
more. The first type is fired from the shoulder and one
person can operate it by night or day. It has a range of
10-15 k. Some of the most famous types is Stinger
(diagram 1) and the Russian IGLA missile. Both are
among the most modern shoulder-fired missiles. This
weapon is very effective against aircraft of all types.
The missile is a smart weapon equipped with a thermal
camera that detects infrared radiation coming from the
aircraft's engine and pursues it. The heat-seeking system
is a smart pursuit method that follows the engine's heat source and flies at twice the speed of sound. It can down a
plane flying at an altitude of less than 3,500 meters and is no more than 4 km away.
We will illustrate later how this type of missile operates, its effectiveness, and the manner in which it is used. We
will acquaint ourselves with the role it plays against the US occupation forces in Iraq and Afghanistan and the
Russian occupation forces in Chechnya.
Diagram 1: Stinger FIM92 surface-to-air missile. After its initial production this missile was developed into versions
A,B,C,D,E,F. There is also an air-to-air version ATAS that the air force uses.
[pg 26]
1. Smart Short-Range Surface-to-Air Missiles
Short-range surface-to-air missiles were designed to provide land forces with an effective weapon to engage lowflying
fighter aircraft and helicopters. From the perspective of the mujahidin fighting on the ground, low-flying
hostile aircraft pose a real threat because they carry out bombing raids, perform reconnaissance flights, land or
evacuate troops, or bring fresh supplies to the enemy forces (figs 3, 4). Downing these planes is the easiest way to
get rid of this threat.
The best example that we can give is the downing of 10 helicopters of all types including Apaches, Blackhawk, and
Chinook, in a single month. Indeed an F-16 was downed in Al-Karmah area west of Baghdad. This operation was
carried out by the mujahidin of the Islamic State of Iraq in cooperation with the Al-Mujahidin Army on Monday, 27
November 2006.

Diagram 2: The mujahidin of the Islamic State of Iraq fire a surface-to-air missile at a Chinook helicopter in Al-
Karmah area. Mere seconds after the missile was fired the helicopter and the troops it was carrying turned into a ball
of fire. The center picture shows the guided missile flying towards the target. The news of the 7 February 2007
operation was published by Al-Furqan Media Production Establishment.
These missiles use unicolor thermal sensors to detect infrared radiation. The sensors operate in the 3-5 micron
frequency range to detect the radiation coming from the aircraft's engine that is produced by CO2. This radiation has
a wavelength of 4.2 microns. The missiles have sensors that largely resemble thermal cameras operating within the
8-13 micron range, which gives them a high resistance against countermeasures. This frequency is barely absorbed
from the air and the sensors are bicolor sensors. The newest sensors now used are Insb and HgCdTe.
The advantages that make this type of missile an effective weapon include the fact that it is light and easily
transportable. The missile and launcher together weigh 15-18 kg. The launcher can be re-used and the missile alone
weighs 10-11 kg. One person can carry the launcher and fire the missile by day or night. Using this type of missile is
referred to as 'fire and withdraw.' After firing the missile, the combatant can immediately withdraw from the place.
The missile automatically follows the target, using its built-in computer that relies on digital, thermal images.
[pg 27]
The result of the analysis of these images are relayed to the automated control system that directs the missile toward
the target. It does this by altering the direction of the front guidance wings. This type of control is known as the
feedback control system.
This weapon has attractive qualities and many armies have sought to possess it. Many countries have also sought to
manufacture it and make it a cornerstone of their air defense systems.
Diagram 3: Helicopters are easy targets for surface-to-air thermally guided missiles. Shown in the picture is a
Blackhawk helicopter used for landing troops. Several Blackhawks were downed among a total of 10 helicopters
downed in one month.
The infrared sensor is able to pursue the heat radiating from the aircraft's engine. This sensor is described as
'negative' because unlike radar-guided missiles, it does not need to send out radar waves from a ground launcher in
order to pursue its target. It follows the target by itself without ground support. The missile uses solid fuel with a
high heat yield. To protect the person who launches the missile from the heat, the missile is launched in two stages.
In the first stage the missile is ejected outside the launch tube and after it has reached a sufficient distance, the
missile's engine is switched on and allows the missile to fly at twice the speed of sound or faster.

Diagram 4: Interior of a Blackhawk helicopter. The red circle shows the night-vision screen while the blue screen
shows the positioning system that uses satellite-fed information together with digital maps.
[pg 28]
2. How To Operate a Surface-to-Air Missile
To fire the missile, the mujahid must follow the target through the missile's viewfinder. The firing system, which
basically rests on the thermal sensor, sends a special signal indicating that the target (aircraft) is within the missile's
firing range. This is known as locking the target. The mujahid then presses the trigger and the launching motor ejects
the missile out of the shoulder-held launch tube. In this way the missile is at a sufficient distance from the mujahid
when it automatically ignites the main motor that runs on solid fuel. The missile then flies at a high speed, which in
certain models reaches 2,448 km/hr. This is twice the speed of sound and is referred to as Mach II (figs 5, 6).

[pg 29]
The missile can fly at an altitude of 3,000 meters and pursue any target up to an 8-km range. Generally this means
that it can destroy any plane that appears in the sky with a high rate of success on condition that it can be clearly
seen and does not appear as a mere dot. New models of this missile are able to overcome countermeasures used by
the planes.
Some launchers are equipped with a system known as IFF to identify friendly and hostile planes (optional). It is a
coded digital communications system that sends a wireless signal to the plane requesting identification. An
electronic system in the plane responds automatically by sending a signal identifying itself. The signals are in code,
which means that the plane cannot respond unless it knows the cipher used. Failure to respond means that it is a
hostile plane and it is then attacked with a missile.
Diagram 7: Area covered by a short-range surface-to-air missile and percentage of likelihood that it will hit the
target. This illustration pertains to fighter aircraft that fly at a speed of over 250 meters per second. Regarding
helicopters, the area covered becomes circular, which means that it is possible to down a helicopter from any
direction within a 4-km range. If a missile is fired at a helicopter in the 1,000-2,000 meter range, a direct hit is
certain. This range is referred to as the kill zone.
The missile should only be fired if the target is flying at a low altitude and within a firing range not greater than
4,000 meters and at an altitude under 3,000 meters. The likelihood of hitting a fighter aircraft as it approaches is
much greater than when it is moving away because the missile might not be able to catch up with the target if it is a
fast fighter aircraft (Figs 7, 8).
One missile can destroy a plane costing more than $30 million (price does not include crew). The element of
surprise is important in downing a plan. A few seconds separate the firing of the missile and its hitting the target.
[pg 30]

Diagram 8: One of the mujahidin steps on the remains of an F-16 downed by a surface-to-air missile. In this
particular operation the mujahidin of the Islamic State of Iraq also downed several Blackhawk helicopters with the
help of the Al-Mujahidin Army.
3. Electronic Control System and Pursuing the Target
A surface-to-air missile uses infrared-operated thermal sensors. They are in the form of a thermal digital
photography camera that senses the thermal images coming from the plane's engine. The missile follows the heat
source. Some missiles use ultraviolet sensors to distinguish an illusionary from a real target. The illusionary targets
are flares that planes drop when their radar discovers a missile moving toward them before the missile can reach
them. These flares emit a lot of heat to divert the course of the missile and make it explode far from the plane. The
thermal digital camera is made up of a network of sensors measuring 2 x 2 in the older models and 128 x 128 in
newer models.
When the target is detected, the missile's electronic system determines whether the target is within the killing range.
After this the missile is aimed so that the target is in the center of the viewfinder (diagram 9). At this point the
missile gives the lockdown signal, which means that the thermal sensor will pursue the plane and the missile is fired.
Diagram 9: A military transport plane as seen by the thermal camera mounted on a surface-to-air missile. This plane
can be easily downed. The black color shows the heat coming from the engine.
[pg 31]
The missile is equipped with a control and guidance system and a computer that handles digital images in real time
(diagram 10). The camera is a passive sensor receptor, which means that it receives infrared radiation but does not
send out any itself. The missile flies towards the target at a high speed. It revolves constantly to maintain stability
while flying. Since the target is moving, the thermal image starts to move away from the center of the viewfinder
indicating that the target has moved out of the missile's path. The control and guidance system corrects this
automatically (diagram 11)

Diagram 10: Blueprint of a surface-to-air missile control system operating by infrared. The navigation system
analyzes the digital images through a digital treatment unit. It controls the missile's wings so that the target is kept in
the center of the viewfinder. This means that when the target is in the missile's path, it takes mere seconds to reach
and destroy it.
Diagram 11: The missile's control and guidance system analyzes the images and determines how far the target has
moved out of the missile's path. It corrects this automatically by altering the direction of the missile's wings, thus
pursuing the target and keeping it constantly in the center of the image.
Left image: The plane appears in the center of the missile's thermal camera.
Right image: The plane has moved to the left. This change of position appears clearly in the center of the thermal
camera.
When a mujahid prepares to fire a missile, the target must be clearly seen and must be nearly at the center of the
viewfinder. When targeting a supersonic fighter aircraft, the target must be flying at an altitude lower than 3,000
meters and must be approaching, not moving away, because the missile cannot catch up with a plane that is flying at
a speed greater than 250 m/s (900 km/hr).
[pg 32]
Additionally the plane must be within the effective range, meaning that it should not be farther than 4,000 meters
away. A plane might pass sideways without the mujahid being able to down it because its speed is the major factor
in his inability to hit it. Transport and cargo military planes and helicopters are slow enough to be hit when they are
within the effective range regardless of whether they are approaching or moving away. Their speed is relatively slow
compared with the missile's speed that might reach twice the speed of sound. Hence the effective range is found
within a circle with a radius of 4,000 meters (diagram 8)
Although the missile might be able to fly twice the distance of the effective range, it is fired only if the target is
within this range. There are two basic reasons: The missile's ability to follow the target depends on its sensing a
sufficient quantity of its engine heat. This means that the target must appear clearly in the missile's viewfinder prior
to the firing. The second reason is that after it is fired, the missile will fly an additional distance during which the

target will try to evade the missile. In most cases the missile's solid fuel is sufficient to cover a distance of 8,000-
10,000 meters.
4. Countermeasures
When a helicopter releases very hot flares (diagram 12), it can escape from an infrared-guided missile. Nevertheless
some types of missile can overcome such evasive action.
Diagram 12: A Cobra assault helicopter releases very hot flares to try to deceive and keep away surface-to-air and
air-to-air missiles that follow the heat source (right).
A military transport plane tries to evade a thermal-guided missile (left).
[pg 33]
The red square shows the helicopter's location and the red circle shows the heat coming from the engine. We can see
that the flares produce an amount of heat greater than the plane's engine (diagram 13). These pictures are in reverse
color (black hot).
Diagram 13: This is how the missile's camera sees the Blackhawk helicopter in diagram 9 (right) and military cargo
plane (left). Such evasive measures can be counteracted by using missiles that have ultraviolet sensors in addition to
infrared sensors.
Russia manufactures shoulder-borne air defense systems (MANPADS) that can overcome the target's evasive
measures. The 9M32 (Sam 7) series was updated into an improved version known as 9M34 Strella-3 (SA-14
Gremlin). This was later replaced by the IGLA 9K38 or SA-18 Grouse and 9K310 IGLA or SA-16 Gimlet. The
IGLA series is provided with a heat-searching device that is cooled with bicolor nitrogen. The missile has a 2-kg
warhead that includes 390 grams of TNT. It possesses a high resistance to flares and can distinguish the real target
from among the false ones. This is done through the use of additional ultraviolet sensors. The IGLA is technically
equivalent to the US-built Stinger missile FGIM-92 (Table 1).
The following picture (diagram 14) shows the newest system that aircraft use to escape an infrared-guided missile
moving toward them. When a radar-guided or thermal sensor-guided missile is detected moving toward the plane,
the plane operates a laser-based jamming system. This system locates the missile's position and directs toward it a
high-intensity laser beam that disables its thermal camera by forcing it to absorb high quantities of energy. If this
operation works, the missile loses visibility and destroys itself automatically after it loses the target.

All the above measures do not have a high rate of effectiveness, especially when defending against short-range
missiles because the time period between firing the missile and its hitting the target is less than five seconds in most
cases. This does not give the pilot any time to adopt evasive measures. Furthermore modern missiles like SA-16
have a system that counteracts the evasive measures. All these new technologies reduce the likelihood that the
missile will hit the target by no more than 6% to 18%.
[pg 34]
Diagram 14: The newest countermeasure that aircraft use to evade infrared-guided surface-to-air missiles. After the
missile approaching the target is detected, a laser device directs a high-energy beam to make the missile's thermal
camera absorb a lot of energy, thus disabling it and sending the missile away from the target.

5. Conclusion
A report by Western intelligence agencies states that 500,000 surface-to-air missiles are spread throughout the world
and it is impossible to control their transfer from one country to another. According to statistics about their uses,
Western sources have reported that the Afghan mujahidin downed 269 planes during the Russian occupation by
firing 340 shoulder-borne surface-to-air missiles. Despite the small numbers mentioned by these statistics, they give
a clear indication that these weapons are effective.
During the first Gulf war, or what was known as Desert Shield, Iraqi infrared-guided missiles hit their targets 80
percent of the time, including fatal strikes 56 percent of the time. According to intelligence reports these missiles
proved highly effective in downing civilian [as received] planes with a 70% success rate, causing fatal crashes.
"In the foregoing study we identified shoulder-borne surface-to-air missiles, the way they operate, and how to use
them effectively both against supersonic fighter aircraft, helicopters, and slow-moving military transport and cargo
planes. We discussed the newest technology that planes use to evade approaching missiles by using
countermeasures. We illustrated the effectiveness of these countermeasures against modern smart missiles that use
thermal photography and ultraviolet sensors to neutralize the countermeasures that the target planes use and how
they can distinguish between a real and false target.
We would like to remind our dear readers that the mujahidin have demonstrated their skill in using these weapons in
a noticeable fashion. The use of these weapons is causing huge losses to the US occupation forces in Iraq and
Afghanistan. A missile carried on the shoulder by a mujahid can down a helicopter that costs more than $10 million
or a fighter aircraft costing tens of millions of dollars, not counting the human losses represented by the soldiers who
are killed in the operation.

Video Series - Question and Answer (Part Two)
by Mujahid I'lami
In this article we will do the following, God
willing:
1. Add some terms to the previous
article to complete the glossary.
2. I will talk about the sampling rate
and horizontal size.
3. The vertical sampling rate and
vertical size will be the same as
before.
4. Some troublesome technical
information about the types of
reception programs and the
general differences among them
will be explained.
1. New Terms
Let us begin by reminding ourselves of certain points:
A television signal, as we said previously, consists of dual lines (that will compose the dual field) and single lines
(that will compose the single field). These lines are called sweep lines.
As we noticed in a previous picture (I will illustrate it again here) the electron beam travels from the left side of the
screen to the right side to draw a sweep line and then returns to the left side to draw a new line. This return is called
horizontal retrace.
[pg 39]

As we mentioned previously, the fields are shown by a frequency of 50 fields per second (PAL) and 59.94 fields per
second (NTSC).
The fields are separated from each other by what are called 'vertical blanking interval' lines and are written as VBI
lines for short. They do not show on the screen. They have a function, but that does not interest us here.
So why do we mention them if their function is unimportant?
We mention them because these lines do not carry any data about the picture but they do carry other already known
data (for the sake of synchronicity and other purposes).
What do these words mean? Whether they carry known or unknown data, how does this interest me?
It interests us to know that we do not need to save any data about these lines when we receive visual television data
because their data are already known. What happens is that the reception device or capture card ignores these lines,
thus reducing the size of the received visual data. When we operate the visual material, the operating device forms
these lines by itself because it already knows their content as we said before.
Hence there are lines on the screen that carry picture data and others that do not. Let us call the lines that carry data
active lines.
This method of showing the picture on the screen, in the presence of fields, is called interlacing. All non-digital
television signals use this method.
[pg 40]
Before we continue, I would like to state that in the next passage you will see some numbers. They do not interest us
as much as the general idea interests us.
A PAL signal line takes 64 microseconds to be drawn from the left side of the screen to the right side. This line
carries data about the picture but not throughout its entire course. Of the 64 microseconds around 52 carry picture
data. The remainder of the line carries (like VBI lines for example) already known data that are used for
synchronization. Space is reserved for these data since we know beforehand what they contain.
As we previously said, every two successive fields will form a picture (or frame). The PAL system shows 25 frames
a second and 625 lines. The NTSC system shows 30 frames a second and 525 lines, keeping in mind that the
essential difference between the two systems is the color encoding method. If you introduce an NTSC signal into a
PAL television set, the picture will be black and white because there is no color identification agreement between
both systems. This does not today pose a problem because modern television sets are multi-system and can identify
all color encoding methods.
Now we come to a piece of information that might surprise you: on a television screen there is no such thing as a
pixel, only lines. Why?
A pixel is a characteristic of the digital signal. A television signal is non-digital and consequently we cannot say that
the screen's accuracy will be (so much x so much) as in the case of a computer screen. When we describe a
television screen, we say that it is either PAL (containing 625 lines) or NTSC (containing 525 lines). It takes 64
microseconds to complete the drawing of each of these lines.
2. Horizontal Sampling Rate
We will now move on to something completely new, namely, the sampling rate and size.
As we said when we identified reception, the receiver's function is to transform a non-digital signal into a digital
signal (so that the computer will understand it). How does the receiver carry out this function? It carries it out by a
process called signal sampling. To understand what this means let us remember that a non-digital signal (such as a

adio signal) is drawn as high and low waves. A computer does not understand these signals. It understands the 0
and 1 language. How can we transform this signal into zeros and ones?
This is done by specifying a very short period of time, let us say for example 1 millisecond. Every millisecond the
receiver measures the intensity of the continuous signal and records it. It takes a sample of the signal and records its
intensity every millisecond.
[pg 41]
The rate of taking samples is 1,000 times per second. This 1,000 times per second is called the sampling rate. The
following picture explains what I mean.
On the left there is a continuous signal. Specific periods of time are set to take signal samples to test the signal's
intensity. Afterward these measurements become interrupted numbers that are turned into zeros and ones (binary
system) that the computer understands. So, the continuous signal is simply transformed into an interrupted digital
signal that the computer can understand. The transformation passes through three stages: sampling, quantifying,
encoding.
I just gave an example of taking a sample every millisecond, which gave us a sampling rate of 1,000 times per
second (that is, 1,000 Hz). The actual sampling is measured 1,000,000 times per second, that is, it is measured in
MHz.
You are very lucky that you do not involve yourself in all these problems. All you do is tune the VirtualVCR
(reception program) to the picture size, let us say 576 x 704, and you leave it to the receiving device or capture card
to do the following:
• First the receiver will take samples at a high frequency to ensure the greatest accuracy.
• The receiver will then delete the VBI lines about which we spoke earlier.
• It will then delete the empty horizontal lines that do not carry data. It will leave 52 microseconds from
every line, which is the part that carries the picture data.
• After that it will use the samples that it took from this remaining part and distribute them to the horizontal
pixels.
[pg 42]
• Of course the receiver will not forget to merge the two fields so that in the end it will present a picture with
just the level of accuracy you requested, that is, 576 x 704. It will present this ready picture to the
VirtualVCR program to do with it as it likes.

• This, simply, is the function of the capture card. It continues carrying out this function until the film you
want is completed and is ready in a digital form and in the size that you asked. You can then use the
VirtualVCR program to alter or handle it as you wish.
Let us now perform some quick calculations of what we did.
We distributed 52 microseconds of the television signal among 704 pixels, that is, 704 acts of reception (one for
every pixel) in 52 microseconds. If we divide them, we will find that the sampling rate is 704/52=13.54 MHz. This
is the real sampling rate if you request a 576x704 size. You will notice that the sampling rate will differ in
accordance with the size you requested. The bigger the size, the higher the sampling rate.
3. Vertical Sampling Rate
All continuous non-digital television signals are produced by 576 active lines in the PAL system or 480 active lines
in the NTSC system. As we said before, the receiver turns the lines into pixels one by one (it is as if it divides the
lines into equal parts consisting of the pixels that are closely packed, one next to the other in a horizontal line). This
is done horizontally.
It is much easier vertically because there is nothing to divide as the lines move horizontally. The lines themselves
are packed on top of each other and each one may be regarded as one pixel.
Consequently you do not have a big choice in a screen's vertical size. You have two solutions (in the PAL system for
example). You can either choose a vertical size of 576 pixels (the number of the lines) or half of them (288 pixels).
Any other vertical size that you try to choose will distort the picture. This means that you can control the picture's
horizontal size as you wish and by this choice, you will specify the sampling rate to the receiver. You cannot,
however, alter the vertical size as you wish. You must choose one of two options, either 576 or 288 pixels (in the
PAL) system.
[pg 43]
4. A Quick Glance at Receiver Programs
Before we begin the practical application of video reception with VirtualDub or VirtualVCR, we need to answer the
following question:
Someone might say: 'I can see that there are many video reception programs, including VirtualDubMod, VirtualDub,
iuVCR, VirtualVCR, FLYDS, AVIO, and others. Which one should I use?'
Actually you can try all of them and choose what you like and tell us what you think. There are, however, some
points to keep in mind that might save you time.
• There are two types of receiver device drivers: One supports the VfW model. It is short for Video for
Windows. The other supports WDM, which is short for Windows Driver Model. Based on this, receiver
programs come in two classes:
o
o
The first class supports WDM and includes iuVCR, VirtualVCR, and FLYDS.
The second class supports VfW and includes VirtualDubMod, VirtualDub, and AVIO.
• We conclude therefore that the receiver program that you will use depends on the type of device driver that
you have. If it supports VfW, then you are using programs like VirtualDub, VirtualDubMod, AVIO. If it
supports WDM, you are using programs like iuVCR, Virtual VCR.
• The users of either type should not worry because we will, God willing, explain the reception method of the
programs VirtualDub (that supports VfW) and VirtualVCR that supports (WDM).
All right, before you continue, would you like to explain to us the terms VfW and WDM? You have not mentioned
them before.

All right, we will give some general information about VfW and WDM. Some brothers, however, might find this
information too technical and are not interested in it. If they find it too technical, let them ignore it and move on to
what comes after.
General Information About VfW and WDM :(troublesome information that I advise you to ignore completely)
- The VfW is an old program that is not currently developed. Because of its narrow parameters Microsoft has
developed a new device driver, which is WDM (this began with Windows 2000).
- Most video card device drivers are now developed to use WDM.
[pg 44]
- There are programs that can convert VfW to WDM. They are called wrappers. They allow you to receive
video signals by using a program that supports VfW (such as VirtualDub) although your receiver card
supports WDM. You will need a fast decoder when using the wrapper because it will put a big load on the
decoder.
- The VfW is still supported by Windows 98, Windows 200, Windows NT, and Windows XP. The problem
mostly lies in the capture card device driver. New video cards do not possess VfW drivers. Only
Hauppauge possesses a device driver that supports VfW for the sake W2K and XP.
- The VfW does not have a TvTuner. WDM has it.
- If you upload the DirectX 9.0b, and you have PAL and W2K/XP, make sure that you upload the patch with
it. Otherwise your television will stop working.
I did not understand anything!
All right, here is some more.
Some Information about bt8x8 driver:
Device driver for video cards that support WDM for bt8x8 chips:
1. btwincap program: You might have some problems in loading and using. The audio will sound as if it is
mono (that is, coming identically from both speakers so that you do not sense the depth of the sound). The
btwincap is totally compatible with the wrapper, so you can use btwincap VirtualDub combo.
2. The iulab tweaked WDM driver: This cannot be used with VirtualDub because it is not compatible with the
wrapper.
Notes:
• Hauppauge driver programs support WDM and WfW and are supposed to work with Windows 98,
Windows 2000, Windows NT, and Windows XP but they will not allow you full reception.
• bt8x8 chips: This is a decoder that captures the pictures from compatible non-digital (analog) sources like a
television set or a non-digital receiver and converts them immediately into digital form without needing to
wait. All video capture devices that are called (video in) use this type of decoders. There are two wellknown
types (I do not remember their numbers now) but one of them supports FM reception and can only
be used with Windows XP. The other supports Win98.
[pg 45]
Believe me, I have not understood anything and I cannot understand why you are telling me all this!
I know that you find this information strange and some terms do not appear compatible with the general context.
However, when we proceed further in video technology, you will appreciate its value and we will add more
information, God willing. At any rate, I would like to give you the glad news that the bothersome technical
information is finished, thank God.
5. Conclusion

We explained in this article and the previous article the theoretical basis that we will need to understand future
stages in this series. As of the next issue this article will be full of practical applications that will rely on the
explanation I have given.

Translating Movies with Subtitles
By Abu-al-Hasan al-Maghribi
Subtitles serve to translate movies into any
language without recourse to video editing
programs. They consist of a small file that
contains the text of the translation and
synchronous data that is placed next to the basic
movie file and carries the same name but with a
different extension. When the user starts the
movie, the operating program shows the
translation automatically from the small file.
1. Stages of Creating Subtitles
The creation of subtitles usually passes through
two chief stages.
• Stage One: Converting the words spoken
in the movie into a text written in the
required language.
• Stage Two: Dividing this text, in
accordance with the context and period, into small parts that are synchronized with the contents of the
movie (that is, controlling the appearance of each piece of text and the time when it should disappear).
Stage One and the division part of Stage Two are done manually but the synchronizing of intervals can be done by
using an auxiliary program like Subtitle Workshop.
Link of the tutorial:
http://www.urusoft.net/downloads/subtitleworkshop251.zip
1.1 Method of Synchronizing the Intervals by Using Subtitle Workshop
After you open the program, you will need to create a new translation file (from the File menu choose 'Open New
File'). You must then specify which movie you want to work on. From the Movie menu choose 'Open.'
The next picture shows the program screen during the synchronization of the text intervals for the movie 'Abu-al-
Zubayr al-Maghribi.'

Downloading and synchronizing can be done by several methods according to choice. The following is an example
of one of these methods:
1. Download the movie as a text file.
2. Divide the text into small portions. Preferably this should be done while watching the movie.
3. Go to the program screen and play the movie.
4. Keep your finger near the Insert button on the key panel and whenever you hear the first word of every
divided portion, push the Insert button. (This step adds a new portion that is synchronous with the
beginning of the scene.)
5. After completing step 4, you will find that you have the same number of intervals as the number of portions
in the text file. Start at the beginning (from portion 1) and transfer each portion from the text file to the
program in turn.
6. You need to ensure that the ending of every text portion is synchronized with the ending of the interval.
This is done as follows:
a. Make sure that the down arrow is not highlighted so that it will not move to the next interval
automatically.
[pg 48]
b. Activate portion 1.
c. Play the movie.
d. When you hear the last word of the first interval, push the right arrow.

e. You will notice that the program has moved the highlight to the next interval.
f. Whenever you hear the last word of each text portion, push the insert button.
7. Play the movie again through the program and make sure that the synchronization was done right.
After you finish synchronizing the translation, choose save from the menu and you will see the following screen.
Push the SubRip button twice and save the file. Give it a name similar to the movie's title.
This is the result after the completion of transcribing and synchronizing the texts and saving the file.
[pg 49]
If you finish preparing the subtitles for the first language and ensure correct synchronization, you can then open the
text file by using the Diary File and translating each line into the language that you want without touching the
numbers at the beginning of each line or above it.

Problems and solutions:
Diagram showing a part of the subtitle file after opening it in a text editor.
The translation does not appear on the screen although the translation file is found next to the movie file and carries
the same name: This problem is caused by the absence of the add-on pertaining to showing the translation in the
user's computer. This problem can be solved by inserting the add-on called DirectVobSub.
The add-on pertaining to the translation is already in the computer but the translation still does not show when using
rm or rmvb files: The solution is to save the translation file using RealTime instead of SubRip.
2. Conclusion
In this article we explained the method of doing a professional translation of jihadist films so that the subtitles
appear at the bottom of the screen exactly as television channels do. This feature helps to propagate jihadist films
widely and in various languages.

'The Mujahidin Secrets Program: A View From Within'
by the Security Department of the Global Islamic Media Front
The mujahidin's secret program is the first
Islamic encoding program for secure
messaging via the Internet. The program
was devised by the Global Islamic Media
Front's (GIMF) Technical Security Unit.
This program enables the exchange of
messages in a secure way because foreign
programs for exchanging secure
information are unreliable. It is unwise to
use them to protect the mujahidin's secrets.
After security gaps and numerous strong
suspicions surfaced about PGP, the most
famous program that ensures secret
communications over the web, the GIMF
produced its own program that guarantees
communications with the highest possible
level of secrecy, relying on the highest
standards attained by the science of encoding and digital communications engineering. The mujahidin's secrets
program was produced to ensure that the secrecy of messages is protected because it relies on an encoding system
that the front produced. Those who developed it benefited from research done into algorithms that were subjected to
deep analysis by senior scientists and encoding experts.
The art of encoding is treated as an electronic weapon, as indeed it is, because it is the basis of ensuring secure
communications and guarantees the confidentiality of the mujahidin's secrets. Nothing is more dangerous than for a
person to rely on a foreign program to protect his secrets and ensure that his communications are secure. Perhaps he
will discover only after it is too late that the enemy has infiltrated all his communications. Umar Bin-al-Khattab,
may his soul find favor with God, said: 'I will not allow myself to be deceived.' The primary security precaution is to
protect your communications with reliable programs.
The mujahidin's secrets program resembles PGP in its objectives but has new features and a high level of secrecy.
The mujahidin's secrets program has two versions: The People of the Frontlines [ahl al-thughur] version and the
Ansar al-Jihad version.
1. Encryption and Communication via the Networks:
Encryption is a method to protect your communication and information against intruders and spies, and is divided
into two sections: The first type is symmetric encryption, which uses a single key to encrypt and decrypt (the
password), and protects information on the computers so that you do not need to copy the key or the password.
Among the most famous algorithms are (Rijndael, Mars, RC6, Serpent, and Twofish). This type of encryption
should not be used to transmit encrypted information via the networks as it cannot transmit the key or the password.
Another type of encryption emerged, and that is known as asymmetrical encryption. It relies on two keys: a public
key, for the encryption operation, and a private key used to decrypt. Among the most famous of such algorithms are
RSA and ALG.
[pg 51]
The latter is attributed to the creator of the algorithms Dr. Tahir al-Jamal. This encryption is based on the discrete
algorithm. The advantage of symmetrical encryption is that it is exceedingly fast, while the asymmetrical
encryption is slow especially in decryption. This is why the communication via networks programs such as the
Mujahidin's Secrets program use both types so that symmetrical encryption can be used to protect the information

and asymmetrical encryption can be used to protect the symmetrical encryption key. To compare the strength of the
keys with respect to the types of encryption, it is enough to note that a key 256 bits long in a symmetrical algorithm
corresponds to a 15360 bit long asymmetrical algorithm key such as RSA.
With respect to communication networks, email is considered one of the most important modern methods to
exchange messages, be they encrypted or not. In order to safeguard the person communicating, the following
conditions must be adhered to in dealing with email used for secret issues:
1. Do not use American email (Yahoo, Hotmail, etc).
2. Never use your regular personal email, but set up an email specifically for the exchange of sensitive
messages.
3. When registering an email address for private matters, never enter accurate information. Instead, give
fictitious information (name, address, date of birth, gender, etc).
4. Do not log into your private email directly from your machine. A proxy must be used to reach your private
email so that even if your email is being monitored, the IP address that you use to check your email will be
one far away from your location. That is because every IP address in the world is registered in global
databases and knowing the [IP] number used by your computer is like knowing your address. The [IP]
number leads to the internet service provider and the company leads those inquiring about you, to you.
2. About E-mail encryption
The following is a primer on how e-mail encryption works. This encryption is based on a Public Key cryptography
algorithm that requires two keys, Public and Private. The Public key is used for encrypting the data while the
Private key is used for the recipient to decrypt the encrypted message. The two keys work together in what is called
key-ring. Both keys are required to complete the ring.
2.1 Encryption Strength:
One of the main features of a strong encryption is the key length in bits. In Symmetric encryption, some countries
allow only 128 bits encryption. The Unites States and Canada allow up to 256 bit encryption which is very
uncommon. In Asymmetric encryption, serious information security requires a key of at least 1024 bit in length.
Until now, messages encrypted with long keys are impossible to crack. A 1024 bit long RSA key, which is a key
based on 309 long decimal numbers, are up to now impossible to crack based on the most recent research in
computer science and prime numbers.
[pg 52]
A 512 bit long key required five months of continuous parallel processing of 292 powerful computers in 2000. A
2048 bit key is billions of times stronger than 1024 bit key. The strength of the key also depends on an authentic
key generation; this is why using foreign made software programs for key generation is very risky. Foreign
companies that create programs for encryption key generation can access the private key using the public key.
2.2 Public Key:
After generating a public key and a private key, and protecting the private key with a "Passphrase" which we will
explain later, you then need to publish the public key in a public area such as the forums, Internet websites, or
servers especially provided for this purpose. Anyone interested in sending you an encrypted message is then able to
simply take your public key to encrypt and send you the message. The message cannot be decrypted without the
private key which is secret and only you have it. This means that you must first send your public key to any person
wanting to send you an important message.
2.3 Private Key

The private key is used to decrypt messages encrypted with a public key. You must protect this key in a secure
location. Make copies of both the private and public key (Key-ring) and store them in a safe place, because if you
lose these keys you will have no other way of recovering the encrypted data and messages. You should also
generate other keys for future use.
3. Mujahidin Secrets Program
The program Mujahidin Secrets offers absolutely the highest encryption level in asymmetrical encryption for
exchanging messages and all sorts of files over networks. It is the first Islamicly produced program to provide this
kind of encryption: 256-bit symmetric encryption and highly secret 2048-bit key asymmetric encryption. The
program incorporates the highest pre-encryption data compression levels for size reduction. It uses a new technology
called "stealthy encryption" that enables the program to randomly change the encryption algorithm every time a file
is encrypted and to produce a random session key that changes each time, thus making it possible to thwart attempts
to analyze encrypted files, since each file is encrypted with a different algorithm from the list of five algorithms that
the program uses. Mujahidin Secrets uses the five algorithms chosen by encryption experts in the AES algorithm
selection filters. All of them have keys of 256 bits.
[pg 53]
Asymmetric encryption technology allows public keys to be transmitted across the network. Public keys can be
posted in jihadist forums. The key's fingerprint can be used to verify the identity of the communicating party. The
public key can be used to encrypt files before sending them. The keys used are themselves encrypted and cannot be
used or analyzed by other programs.
Diagram 1: The main page of the Mujahidin Secrets program produced by the Technical Security Unit of the GIMF

4. Features of the program
• Encryption using the five best cryptographic algorithms (AES finalist algorithms)
• 256-bit symmetric encryption keys (Ultra Strong Symmetric Encryption)
• 2048-bit asymmetric RSA encryption keys (public and private key pair)
• Incorporated data compression (highest compression levels, Zlib compression)
• Variable keys and algorithms by stealthy encryption technology (Stealthy Cipher)
• Auto-detection of encryption algorithm upon decryption (Cipher Auto-detection)
[pg 54]
• Secure file deletion technology, so that files can be deleted without possibility of recovery (Files Shredder)
• Program consists of a single file needing no installation and operable from flash memory
5. Keys Management
When the program is started for the first time, the key database will be empty. Click on the button "Keys Manager,"
and you will get the following window:
Diagram 2: Encryption key management window
Click on the button "Generate Keys," and you will get the following window:

Diagram 3: New Key Pair Generator window
[pg 55]
Fill in the fields for "Username," "Passphrase," and "Confirm Passphrase." Then click on the button "Generate
Now." If your computer supports Arabic, you can use Arabic in defining the username and passphrase. Click on the
writing direction buttons to select the language script (Arabic / Roman). Generation of a 2048-bit key may take
between two and five minutes on a computer operating at 2.4 gigahertz (2.4 billion cycles a second).
At the time of key production, the program is frozen and exploits the microprocessor at 100%. After the key pair has
been generated, you can close the window. The information in "Status" will show you the amount of time that key
generation has taken. After the operation is finished, there will be two new files with the format
publicXXXXXXXX.akf and privateYYYYYYYY.akf, where the number XXXXXXXX represents the Key ID of
the public key, and YYYYYYYY represents the Key ID of the private key. The two are saved in the same folder as
the program. The two keys should be copied and moved to a secure place (e.g., a compact disk or flash memory) as
a kind of reserve copy, since encrypted information cannot be retrieved by the public key without the private key.
After generating the keys, you can activate them by importing them into the database of active keys. Click on the
button "Import Key." You will get the following window.
Diagram 4: Public and Private Key import window

Import the two keys (public and private) one after the other. When importing the private key, the program will ask
you for the passphrase, because every private key is encrypted with its own passphrase. After incorporating a
number of keys, the Keys Manager window will have the following appearance:
[pg 56]
Diagram 5: The Key Management window after importing some keys
Public keys will appear in blue with a blue key icon ; private keys will appear in pink, indicated by a blue and red
icon of two keys . The blue key stands for the public key; the red stands for the private key. The currently selected
key will appear in yellow. Keys that are imported become active in the database located in the file AsrarKeys.db.
The keys can be dispensed with after their incorporation into the database, but they must be kept in a secure place as
a reserve copy.
To delete a key from the database (the list of active keys), select the particular key, then click on the button
"Remove Key." The key will be deleted from the database, but the original copy from which the key was imported
will remain. When a public key is selected, a copy of it can be exported by clicking on the button "Export Public
Key." 2048-bit keys are secure for a period of more than ten years. However, one cannot even talk about the
maximum period of validity of the program's current keys, because the keys are compressed and encrypted to
prevent any usage of them in other programs. Following is an example of the file of a 2048-bit key encrypted.
If you get a public key in text format at a forum, you can copy the content, save it in a file with the extension ".akf,"
and then use the Keys Manager in the program to incorporate it into the database of keys by means of "Import Key."
[pg 57]

Upon selecting a private key, you can export a new copy of it or export the public key associated with it, because the
private key contains both keys together (a key pair). If you import your private key, there is no need to import your
public key also, as the public part of it is used to encrypt and the private part is used to decrypt. At the same time,
only the public keys are visible to the parties with whom you correspond. You can change the passphrase that
protects your private key and also protects the key pair file by means of "Change Passphrase."
When you click on the Change Passphrase button for a private key, you will see the following window. You enter
the current passphrase and the new passphrase, along with confirming the new passphrase. Then you click on
"Apply Change," and close the window to return to the Keys Manager window.
Diagram 6: How to change the password that protects the private key
After changing the passphrase, do not forget to export and save a new copy of it, using "Export Private Key." The
old file will be replaced by the new one after the program asks you to confirm the replacement.
Diagram 7: When importing a key from the database, make sure it’s on the disk before deleting it
To get information about a particular key, double click on it. If you have requested information about a public key,
you will see the following windo where the picture shows that the information is about a public key and displays the
fingerprint of a single key.

You can now copy the key information by clicking on the "Copy" button and paste the information into the place
you wish. This information must be published along with your key. The key's digital fingerprint is what verifies that
you are the owner of a particular key. However, you must communicate this information to the party with whom you
wish to correspond by several routes, so that this party can verify that you are the owner of a particular key. To
compare a digital fingerprint you have obtained with the digital fingerprint currently in the Keys Manager, use the
Compare Fingerprints window by clicking on the button . Copy the fingerprint and paste it into the field FPb.
Diagram 9: Comparing the digital fingerprint of the keys
You can also save the key information in the form of a text file by clicking on the button "Save as” (Diagram 8).
If you have asked for information about a private key, you will see the following window. The picture shows that
the information is about a private key and shows the picture of a key pair (private and public). Look at the following
illustration:

5. Secure File Deletion -- File Shredder
Because the files with which you work have a private character and require complete secrecy in dealing with them,
the program provides a feature for secure deletion of files with which you deal that are located on the computer's
hard disk or on portable memory. The file deletion feature that the computer's operating system uses is not secure:
files that you have erased using "Delete" can be recovered by using special programs known as Files Recovery. This
is due to the nature of the deletion process used by the operating system.
The system does not really erase the files; it merely deletes their identification in the system in order to enable
writing in their location on the disk in the future. This allows the files to be recovered in many cases. When you deal
with secret files, you can take advantage of the secure deletion feature that the Mujahidin Secrets program provides.
It actually shreds the file. This is done between four and ten times automatically.
The following window shows you the File Shredder service. After you select the folder in which the files are
located, the latter appear in the list of the current folder's files. Select the files you wish to shred by pressing the Ctrl
key and clicking on each file. Then drag and drop them, using the mouse, into the basket of target files for
shredding. You can also double click on each file to move it to the basket or double click on it inside the basket to
withdraw it from shredding. To destroy all the files in a particular folder, click on the button "Select All." After you
have finished selecting the folders, click on the button "Shred Files." The program will ask for a final verification of
the shredding process, after which the files will be finally destroyed. To see a refreshed file list, click on the button
"Refresh." To cancel the shredding of files, delete the file list in the basket by clicking on "Clear." You can see the
files of a certain type in the current file list by using "Filter Extension," which displays the files ending with a
particular extension. To display all files, use the extension *.* in the file filter. While the shredding operation is in
progress, the bottom strip will show the shredding operation and the number of times the files are wiped out. You
use “Options” to set the number of times of secure wiping out.
[pg 60]
The higher the number of times, the slower the operation, especially for large files, although you will not notice the
difference for small files (under a megabyte).

Diagram 11: Secure File Shredder window
7. Options
7.1 Data Compression
You can select compression ratios before encryption. High compression ratios require some time to process the data
(a few extra seconds for compression) for large files (above 10 megabytes), while compression speed is greater for
small files (less than 3 megabytes). Data compression is particularly important for text files (reports, messages,
communiqués, etc.). Compression ratios can reach many times. Compression speed ranges between 10 and 100
megabytes a second. The program provides four options: rapid compression, medium (normal) compression, high
compression (slow), as well as offering the option of turning off compression.
While it is recommended to use high compression in most cases, turning off compression is preferable in the case of
large video files (above 50 megabytes), because compression yields only small ratios. This is because the nature of
the files is compressed originally.
[pg 61]
The compression ratio ranges between 0% for already compressed files and 1,000% for text files and some types of
picture, and it is sometimes much greater (See the bottom of diagram 1).
7.2 File Shredder
Here one can select the number of wipe-out times for a file so that it cannot be recovered. The available choices are
4, 6, 8, and 10 times. When options are changed and saved by clicking on the "OK" button, a file named "asrar.ini"
is created with the new settings. By clicking the "Cancel" button, the current changes are ignored. The following
window clarifies these options.

Diagram 12: File Compression and Secure Shredding options
8. Encrypt File Using Public Key
Select the file you wish to encrypt ("Select File to Encrypt"). Then double click on the public key of the party with
whom you wish to correspond. The selected key will appear in "Recipient User ID." Then click on the "Encrypt"
button. When you double click on a key, its color will change from yellow to red, showing that it is the key that will
be used in encrypting.
[pg 62]
Diagram 13: Main page showing the information’s high compression rate

If you select "Stealthy Cipher," the encryption algorithm will automatically be selected randomly. On the other
hand, if you turn off the Stealthy Cipher feature, you can set the encryption cipher from one of the five available
algorithms. If you wish to delete the original file permanently after completing the encryption process, select "Wipe
Out Original File." If you select this service by mistake, there is a final chance to back out, because the program will
ask you to confirm the deletion of the original file. After you click on the button "Encrypt," a window asking you to
wait will appear. The operation takes place in three stages: compression, encryption, and finally saving the
encrypted data. The encrypted file is given the same name as the original file, with the addition of the extension
".enc," and is saved in the same folder as the original file. Encryption speed usually is in excess of 15 megabytes a
second. After encrypting a file with the public key, it cannot be decrypted without the private key.
Diagram 14: Compressing the information, then encrypting and finally saving it.
[pg 63]
At the conclusion of the process, a message will appear, telling you that the encryption process has been
successfully completed.
Diagram 15: Showing that the operation was completed successfully
If you request that the original file be deleted automatically after encryption, the message will be the following.
Diagram 16: The Key Management window after importing several keys and indicating that the original file was
permanently deleted
9. Decrypt File Using Private Key

When you receive a file encrypted with your public key that has been posted in the forums, for example, you can
decrypt the file using your private key. Select the encrypted file ending in the extension ".enc." Select the private
key (pub/priv) by double clicking on it, so that the key's color changes from yellow (the key's current color) to red.
Then click on the "Decrypt" button. The program will ask for the passphrase for the private key: decryption is
impossible without the passphrase because the private key has been encrypted using the passphrase. Because the
strength of encryption depends on a 256-bit algorithm, a password of length adequate to the encryption strength
must be used. The length of the passphrase will range preferably between 20 and 36 letters.
[pg 64]
Diagram 17: When decrypting a file, the program asks you for the password that protects the private key
If the passphrase is below the minimum, you expose your private key to danger if it is stolen from your computer.
The real danger to your keys is the same danger that threatens your computer: spy programs that enable their owners
to penetrate your internet-connected computer and steal your files.
Diagram 17 [as published]: The decrypting operation
When you click on Decrypt and there is a file with the same name on your computer (in the same folder), the
program will inform you of it and ask you to confirm the replacement of the file bearing the same name or cancel
the operation. If you do not wish to replace the file, cancel the operation. Then change the name of the affected file
and repeat the decryption. This is made clear in the following picture:
[pg 65]

As decryption continues, the following message will ask longer than encryption and lasts a few extra seconds.
Finally, you will receive a message showing that the decryption operation has been successful. If the encrypted file
does not have the ".enc" extension, the resulting file will have the extension ".dec" to distinguish it from the
encrypted file. To use it, remove the extension ".dec" by hand.
10. Software Files
After the program is run, the following additional files are created:
1. A file AsrarKeys.db: an encrypted database containing the keys activated after importation into the
program. This file is created automatically after installation. It is empty until keys are imported into it using
"Keys Manager -> Import Key."
2. A file asrar.ini: an options file created if you change the default settings. The new choices are saved in it. If
you delete it, the program will use the default settings.
[pg 66]
3. The public key file (publicXXXXXXXX.akf) and the private key file (privateYYYYYYYY.akf). These
two files are created after the generation of a new key pair. When the private key is imported into the
program and the public key is posted, these keys become reserves. Your public key need not be imported
into the program, because the private key contains a copy of the public key.

To increase the secrecy of the files, you can change the names of the keys and the program and put them into the
operating system folder. It is recommended that you put them into a miniature password-protected portable memory
that can be easily erased when necessary.
11. Conclusion
The Secrets of the Mujahidin program is a high tech encryption program, which is more sophisticated than the
symmetric encryption programs used internationally. It provides a new feature called the phantom encryption, by
using the best five algorithms in the science of symmetric encryption. The Secrets of the Mujahidin program has
several features that make it the only secure encryption system for jihad usages. The program is composed of one
file that does not require saving on the computer, and can be operated through the downloaded memory. It also has
the feature of secure deletion of the original files "File shredder" or what is known as the final destroyer of original
files, making them impossible to retrieve, and thus you are assured of the secrecy of your files, after their deletion,
God willing.

A Call To Participate
To everyone who reads the following words:
Peace and God's mercy and blessings be upon you.
How often have you thought of doing something to serve this religion and assist your mujahidin brothers in the
media sphere?
Do you think that merely going into a forum and reading the material there without making any extra effort yourself
serves this religion? Brother, when will you move from the stage of merely receiving to the stage of contributing?
Has not the time come for you to exploit your potential abilities and become an active member in the media war
between the mujahidin and the crusader enemies of God?
Dear mujahid brother, the Technical Mujahid magazine is giving you this opportunity. The knowledge that you
possess is a trust that you hold and that you must convey to other mujahidin and forum visitors. Tens of thousands of
mujahidin, their supporters, and Muslims in general will read this magazine on the web. When you contribute an
article, you will garner a great reward from God.
My brother, the technical mujahid: Half of our battle with the enemies of God who have occupied our lands in
Palestine, Afghanistan, Iraq, Chechnya, and Somalia takes place on the media. It requires enlightening the Muslims
about this Crusader war against the Muslims. The jihadist media have already made huge successes. The enemies,
even before our friends, have admitted this.
My brother, the technical mujahid: You can begin as of today to contribute your creative work and scientific articles
that interest the mujahidin and their supporters who visit the websites. We will publish your articles in our magazine
so that what you write will reach tens of thousands of readers, Muslim brothers like yourself, who urgently need this
knowledge. We still remember the relevant call made by Shaykh Abu-Hamzah al-Muhajir, may God preserve him.
Brother mujahid, have you not heard the Hadith of the prophet, may God's prayers and peace be upon him: 'When a
person dies, all his work ends except for three things: arrangement for his money to continue to be used for charity,
useful knowledge that he has left behind, and a pious son who will call down God's blessings on his soul.' Do you
not like for your contribution here to benefit others after you are gone?
[pg 68]
Dear technical mujahid brother, you shoulder responsibility to the extent that you have knowledge. Do not think that
even a small contribution is not valuable. Perhaps a brief article you write will benefit a mujahid struggling in the
cause of God or protect a brother from harm. You will then get a great reward, God willing.
The editorial staff will be very pleased to see your articles and creative work in the service of this great religion. The
fields in which we expect articles are numerous and wide and not restricted to any particular technical subject. We
can benefit from any technical contribution although in these early issues we are focusing on the security aspect of
using the Internet because of its great importance for the mujahidin who struggle in the cause of God. For them it is
a matter of life or death.
Finally, we ask God to give us and you success in our endeavor to uphold this religion.
Important Notes:
1. Every article that is sent to us will be reviewed by a team of experts. After it is approved for publication, it will be
checked for accuracy and then published.
2. The magazine will be interested in every article that reflects a great and distinguished effort and is backed by as
many pictures as possible.

3. If your article is not approved for publication, this will not necessarily mean it is not suitable for publication but
there might be, in the editorial staff's judgment, certain reasons to hold it back. Use will be made of it, however, and
it will be passed on to the workers at other jihadist media offices.
4. When you send an article, please use a pseudonym or a nickname. This will appear with the article in the
magazine.
5. Use all possible means to hide your real identity when you communicate with the magazine. The enemies of God
are always lying in wait for the Muslims.
6. Send your contributions to this address:
