How to use:

Get and use Firefox 3.
Get and install FireGPG, a Firefox extension that makes dealing with keys in webpages (like the above) easier.
if you're not using an OS such as Ubuntu with PGP apps included, get GnuPG so you can actually create/manage keys.
Get Enigmail (and, if you haven't yet, Thunderbird to install it on.)
Create a keypair by going to Thunderbird > OpenPGP > Key Management > Generate > New Key Pair
Import my public key, either by clicking "import key" in the blue box above (you'll see it once you install FireGPG and restart Firefox), or by searching me on the keyservers. (Thunderbird > OpenPGP > Key Management > Keyservers, type in "Binkovitz")
Compose a message to me (users' e-mail addresses are included in their keys) and before you send it, click "OpenPGP" (it says it two places, either is fine) and check "sign message" and/or "encrypt message. If you sign a message, I know it could only have come from your private key. It also sends me your public key, so I can encrypt messages to you if I want. If you encrypt a message with my public key, you know only my private key can decrypt it.
Now we can exchange military-grade secrets, whee!
