Sacramento's cryptoparty is a free social gathering for discussion of all things security. We're open to all skill levels and interests and hope to teach the community about encryption and security basics.
For our first cryptoparty, we will focus on email encryption: the basics of public key cryptography, setting up a mail client to use PGP, creating and signing keys.
Bring a laptop if you have one. Spare Linux machines will be available to practice on if you don't. Memory sticks or portable hard drives will help if you plan to use one of these.
You can get a head start by installing these: gpg (gnupg.org (http://gnupg.org/)) , Mozilla Thunderbird (www.mozilla.org/thunderbird/), and enimail (enigmail.net (http://enigmail.net/)).
Bring picture ID so people can sign your keys.
