PGP Public Key
How do I know you are who you say you are? How do you know that I am who I say I am? These are some of the items that PGP addresses that many aren't aware of. Sure you can encrypt a message and send it to me me by using my public key, ensuring that I'm the only one who can read it, but digital signatures are also possible. Digital signatures enable a good client mail reader (like Mutt or Thunderbird) to automatically parse the digital signature contained within an email message and verify it on the fly as you're reading your mail. Making use of these programs is just one more way of keeping out those who would like you to believe they are someone they aren't.
I wrote the above in 2003 way before anyone really cared all that much about eavesdropping, man in the middel attacks, or similar ways to compromise your personal information. Its more critical now certainly than it was then to have these measures in place, and yet there are still very few validating each other on the net.
If you want to send me something encrypted, you can get my key from what is called a PGP Key Server. My public key can be found at this key server. MIT PGP Key Server
Just enter my email roger at wilcis dot com at the prompt and the key will be presented to you. If you find more than one, please use the one with the latest date to ensure I have the private key for it. For your convenience, I've also pasted it below.
