Encrypt your communication

Communication, especially email, should be encrypted unless you want people to see everything you say. Do this easily using GnuPG.
GnuPG uses public-key cryptography so that users may communicate securely. In a public-key system, each user has a pair of keys consisting of a private key and a public key. A user's private key is kept secret; it need never be revealed. The public key may be given to anyone with whom the user wants to communicate.
