[vox] Easy Email Encryption

[Brian Lavender]

This still looks tricky. This basically means you have to mail your friend
a set of keys. Quite frankly, I would like to see a talk where someone
demos using Evolution with GPG integrated. I would think it would be
much easier to set up Evolution with your friend to automatically use
a certificate you generated. Or, better yet, a KNOPPIX thumb drive you
use to manage GPG signing. 

Encryption is tricky to do right. This last semester we were able to
crack an AES cipher because of the way it was padded and the Cipher
Block Chaining that was used to perform the encryption and that there
was an Oracle that would tell us if it received a properly encrypted
message. This was a "in-class" exercise, but I am sure if our professor,
Dr. Krovetz, hadn't pointed it out, I would have walked right around it.
