I've played around with PKI stuff for a long time. Just about the only real application I've ever had for it is at work where admins would often use public keys to indicate allowed access rather than username/password pairs.
Recently, I found another practical application: it's a great way to send sensitive information (especially passwords) through the mail.
Theoretically it's also a great way to prevent people from snooping on your conversations. But that's never been a huge concern of mine.
The big drawback to this sort of thing (alluded to in another post) is that you have to a) keep the private key file around, and b) you have to remember the passphrase you used to encrypt your private key. I had an older public key that is now useless because I forgot my passphrase!
Anyway, here's my public key. (I've also sent it to a variety of public keyservers.)
Encrypt something and send it to me! It's fun!
