I'm a big fan of national security and defense, but I'm just as big a fan of the Rule of Law. I'm no expert, but taking charge of securing your own communications seems like a really good idea at this point. Here are a few tools that might help.http://www.law.cornell.edu/constitution/fourth_amendmenthttp://mobile.nytimes.com/2013/06/28/opinion/the-criminal-nsa.html
PGP SMS Lite:https://play.google.com/store/apps/details?id=com.woodkick.pgpsmslite
Sends text messages encrypted once recipient has shared their public key. Paid version has no time/frequency limit.
Menu -> Manage Secret Keys -> Create Keys. Can encrypt message text or any file on your phone. Export and share your public key so anyone can send to you in cipher text.
Good version of Android built-in "Email" client. Install after APG and there will be Sign and Encrypt options for each composed message.
E-mail that uses no servers or storage of messages, can be completely anonymous. Does not "install" and can be used as a portable application, or passphrase can recreate same address anywhere. Still in development, Android version not available yet.https://bitmessage.org/wiki/Main_Page
Can sign and/or encrypt (or decrypt and verify) via Windows shell extension (right click). Kleopatra allows import or export of GPG (including APG) keys or X.509 (CAC type) certs.http://www.gnupg.org
(for other platforms)
My public key:http://db.tt/pgVrF8au
Open with APG to import the public key. Once there you can see the address of the key's recipient. If anyone has a better way to share keys including to a recognized server, please let me know.https://encipher.it
Don't know much about it but supposedly it can mask the IP of any activity.https://www.torproject.orghttps://play.google.com/store/apps/details?id=org.torproject.androidhttps://guardianproject.info
If anyone has more tools that they have used, is interested in cryptography, knows a good forum or source for information, or has some pithy thoughts to share, I'd love to hear it.
