+For most of us, when we first decide we want to encrypt our email, we only think about one half of the equation: scrambling our message in a way that only the intended recipient can read it.

+A second, and equally important component that is often over looked is authenticity. If someone sends you a secret message, how do you know it was sent by the person who is claiming to have sent it?
+
+Encryption (scrambling your message) and authenticity (knowing who really sent the message) are the two pillars of secure communication. You must have both to securely send private messages between two parties. 
+
+Therefore, when sending mail that you want to keep private, you will typically want to both encrypt the message ''and'' digitally sign the message. When receiving email using GnuPG you will typically want to de-crypt the message ''and'' verify the signature.

+Alternatively, if you want to send message and it's not important to keep it private, but you want the recipient to be sure it is you who is sending it, then you may simply want to digitally sign the message and not encrypt it.
