Lavabit and Silent Circle have given up when it comes to providing encrypted email communications. Mega plans on providing something to cover the gap and in general the only real way to deal with privacy-in-email is end-to-end encryption. There was talk that at some point email might give way to writing letters and using the US Postal Service but there as well you’ve got Postmasters writing commands taped to mail about how everything has to be photocopied and stored – so even the US Postal Service is full of spies, the only thing the US Postal Service can be trusted to carry is junk mail.
What is the answer? Pretty Good Privacy. PGP, or rather, the non-Symantec version of it which is the GNU one, the GPG. If you really want to keep what you write private when you send it to someone else, the only way to do that is for everyone to have GPG installed on their email system so you can write email using their public key, which converts your email to cyphertext, secure from even the NSA’s prying eyes, and requires your recipient to unlock the message using their secret key, which they have.
I’ve been playing with PGP and GPG now for a very long time and I decided I would at least make a route available if anyone wanted to contact me with privacy intact – my public keys are on my blog, they are also on all the keyservers including the one hosted and run by MIT and the GPG Keyserver as well. To send me a private message via email all you need to do is get GPG, set it up, create your secret and public key, get my public key, use it to write me an email and only I’ll be able to read it. The NSA will just flag the encrypted contents for later analysis and thanks to AES–256, they’ll be hard pressed to get to the plaintext in your message.
That’s the way around all of this. GPG for everything. GPG public keys for email, for chat, for VPN, for files, and HTTP-in-GPG. Everything pumped through GPG. Since the government won’t stop spying on us, it’s our duty as citizens to secure our own effects against illegal search and siezure, and technology exists to do so.
Encrypt everything.
