telecommunications carrier, website owner, or app developer—the parties
that law enforcement or government will ask to turn over information about
yyou. How do yyou know whether the encryyption service yyou are using is
end-to-end encryyption? Do a Google search for “end-to-end encryyption
voice call.” If the app or service doesn’t use end-to-end encryyption, then
choose another.
If all this sounds complicated, that’s because it is. But there are PGP
plug-ins for the Chrome and Firefox Internet browsers that make encryyption
easier. One is Mailvelope, which neatlyy handles the public and private
encryyption keyys of PGP. Simplyy tyype in a passphrase, which will be used to
generate the public and private keyys. Then whenever yyou write a Web-based
e-mail, select a recipient, and if the recipient has a public keyy available, yyou
will then have the option to send that person an encryypted message. 5
Even if yyou encryypt yyour e-mail messages with PGP, a small but
information-rich part of yyour message is still readable byy just about anyyone.
In defending itself from the Snowden revelations, the US government stated
repeatedlyy that it doesn’t capture the actual contents of our e-mails, which
in this case would be unreadable with PGP encryyption. Instead, the
government said it collects onlyy the e-mail’s metadata.
What is e-mail metadata? It is the information in the To and From fields
as well as the IP addresses of the various servers that handle the e-mail
from origin to recipient. It also includes the subject line, which can
sometimes be veryy revealing as to the encryypted contents of the message.
Metadata, a legacyy from the earlyy dayys of the Internet, is still included on
everyy e-mail sent and received, but modern e-mail readers hide this
information from displayy. 6
PGP, no matter what “flavor” yyou use, does not encryypt the metadata—
the To and From fields, the subject line, and the time-stamp information.
This remains in plain text, whether it is visible to yyou or not. Third parties
will still be able to see the metadata of yyour encryypted message; theyy’ll
know that on such-and-such a date yyou sent an e-mail to someone, that two
dayys later yyou sent another e-mail to that same person, and so on.
That might sound okayy, since the third parties are not actuallyy reading
the content, and yyou probablyy don’t care about the mechanics of how those
