Gnupg Is Pretty Good Privacy

In the interest of security I was playing around with GnuPG at work today. I played around with it a little more once I got home. It’s about the most impressive thing I’ve ever seen – and I’m not joking. It’s a “GNU” version of “PGP”. Basically, PGP is used for encryption and digital signatures. I’ve known about it for years, but haven’t, until now, done anything but read about it. It’s based off some insane cryptography that ends up with a Public and Private key pair. You gaurd your private key with your life, and it is protected with a pass phrase. It is your identity, and the whole point of this cryptography. The public key is mass mailed to everyone you know, and ideally, stored on a keyserver from where it can be easily retrieved.
