10.5 Digital IDs
A digital ID is much like paper-based identification such as a passport. It can prove who you are and give
you special rights to do particular things. In the case of digital IDs in Nitro PDF Professional, your digital ID
can let you make your PDF files tamper proof, as well as give you special access to files from users who
have approved your digital ID. The beauty of digital IDs when securing a document is that you can change
access and usage rights on a user-by-user basis.
Digital IDs are comprised of a public and private key. The public key contains a certificate and identifying
information, and this is what you share with other users. Once other users have your public key they can
secure (encrypt) documents that you may be able to access and use. The private key is the part of the
digital ID that is never shared and is the part of the ID that unlocks (decrypts) files that you have been
granted access to and usage of.
Nitro PDF Professional supports the use of two types of digital IDs:
· PKCS#12 digital ID file. This type of digital ID is more flexible because you can use the same ID on
multiple computers. For example, if you had an office workstation and a notebook with the same
certificate installed, you could open the same secured PDF file on both computers. The digital ID
remains secure when moved between computers as you must enter a password when you import it to
your My Digital IDs.
· Windows Certificate Store. This type of digital certificate locks the ID to a user on a particular
computer and cannot be copied and imported to another computer.
10.5.1 My Digital IDs
The My Digital IDs feature in Nitro PDF Professional lets you to create, manage, and store your digital IDs.
For most users you will probably only need the one digital ID.
