Reconquer your privacy
Arguing that you don't care about the right to privacy because you have nothing to hide is no different from saying you don't care about free speech because you have nothing to say. – Edward Snowden
Using encryption helps to protect your privacy and the privacy of the people you communicate with. Encryption makes life difficult for bulk surveillance systems. GnuPG is one of the tools that Snowden used to uncover the secrets of the NSA.
