(Don't know what PGP is? Start here.)

This is my PGP key's signature:

pub   1024D/569106B2 2002-10-13
      Key fingerprint = D322 1E2D 6C88 01DD 06EB  787A A0F0 3D45 5691 06B2
sub   2048g/7233AA54 2002-10-13

You can get my key from a keyserver using:

gpg --keyserver pgp.mit.edu --recv-keys A0F03D45569106B2

or alternatively, this is it in .asc format.
