Email Authentication or Encryption
I use and strongly recommend GNU Privacy Guard to authenticate and/or encrypt email messages. Anybody with a little technical know-how can create an email message that looks like it came from me, or you, or the President of the United States.
How can you tell that someone's really who their email says they are? If you don't want to phone them up every time you get an email and ask, "Did you send me this," then you're going to want some form of authentication. One widely-used open standard for a quite secure, usable system is called GNU Privacy Guard, or GnuPG. To verify that I'm really me, for instance, you can have your client software use my public key to check a message or document that "I've" signed to make sure that I did in fact sign it using my private key. Bad signature? Give me a ring, an SMS or an IM and let's satisfy ourselves that we're who we really are.
To make working with public keys easier, GnuPG has the concept of a "fingerprint,"
which is a (relatively) short code that is tied to an individual public key. My
3132 C411 DB9F 45AF C7F5 4E64 AED9 5AA1 B4FF F6A4
is tied to my public key; both expire on 30
June 2011 and will be replaced after that date with a new fingerprint
and key. Anything that I sign with the matching private key will still be provably
signed by the then-expired private key, but I will need a new key to create new
signatures after that.
