After all the talk about everything Edward Snowden (Bio) has told us about what NSA and GCHQ are up to for citizens (thats Citizens, not Criminals, Terrorists, or other dissidents; but normal citizens), There is a way that you and I can both try to prevent the government from reading our emails.
Why would we want to protect our emails? the person who says “If you’ve got nothing to hide, you’ve got nothing to fear” (oh?) is usually the person who has least idea what they are saying…
“Qu’on me donne six lignes écrites de la main du plus honnête homme, j’y trouverai de quoi le faire pendre.” / ”If you give me six lines written by the hand of the most honest of men, I will find something in them which will hang him.” – Cardinal De Richelieu
Now I encrypt some emails not just for me, but for others; If normal people encrypt their emails; it makes it harder to spot people who have reason to fear their government (revolutionaries, LGBT, Academics, Whistleblowers, ect)
GnuPG allows to encrypt and sign your data and communication, features a versatile key management system as well as access modules for all kinds of public key directories. GnuPG, also known as GPG, is a command line tool with features for easy integration with other applications
Please have a watch of this video, and see what GPG / PGP can do for you, even if you trust this government, what is to say we can trust the next one? (hint IBM and the Holocaust [link])
