-- OR -- How would you know that a communication is really mine?

From time to time, I will add a digital signature to documents, e-mail
messages, and other material I write or publish. The purpose of the
digital signature is so that one may confirm with certainty that signed
items did in fact come from me. 

Should you wish to verify the authenticity of any digitally signed item
apparently coming from me, you can use the security information below: 

I'm using PGP for digital signatures.

My pgp public key fingerprint is:

My pgp public key is:

Why?:

As host for the learning-org network, I am visible on the net, and I am
active against people who attempt to send SPAM/UCE to the learning-org
list, to me, and to my friends, and I am active against others who attempt
to abuse the net. As a result, I expect that I will eventually be
attacked.

What do I mean by an "attack?" Well, a while ago, I found a message posted
in a very visible spot on the net that appeared to be from a frequent
participant in that location. The message was immediately offensive (yes,
you can guess the worst!) and my first reaction was, "Oh! And, I thought
that was a good person!" Of course, the message was a forgery!
In that case it was a juvenile attempt at humor, but over the last
two years the attacks have become more sophisticated and with higher
potential for damage. Thus, I've decided to be prepared to prove the
authenticity of my communications.
