[olug] PGP keys -- who here uses them?

[Kris Gainsforth]

I have really gotten interested about keys and authentication lately. 
I've just wondered what types of keys and certs that you guys have that
you use to sign mail and sites.  I'm trying to explain to my parents why
authentication and keys are a good thing, and I would like examples from
other people to share.
