use the basic concept of finding keywords.
The "Three Letter Government Agencies" have
been intercepting electronic communication
for decades... a famous obsolete list of keywords
is called ECHELON.
This list is published online and shows what

Criminal investigation by US Customs
After a report from RSA Data Security, Inc., who were in a licensing dispute with regard to use of the RSA algorithm in PGP, the Customs Service started a criminal investigation of Zimmermann, for allegedly violating the Arms Export Control Act. The US Government had long regarded cryptographic software as a munition, and thus subject to arms trafficking export controls . At that time, the boundary between permitted ("low-strength") cryptography and impermissible ("high-strength") cryptography placed PGP well on the too-strong-to-export side (this boundary has since been relaxed). The investigation lasted three years, but was finally dropped without filing charges.
It's personal. It's private. And it's no one's business but yours. You may be planning a political campaign, discussing your taxes, or having a secret romance. Or you may be communicating with a political dissident in a repressive country. Whatever it is, you don't want your private electronic mail (email) or confidential documents read by anyone else. There's nothing wrong with asserting your privacy. Privacy is as apple-pie as the Constitution.
