Do you know what PGP is? If not, start
here.
When you know someone\'s PGP key, you can make sure that a (PGP-signed) email, file, etc. really comes from that person.
Geeklog has a security-related background (Jason originally wrote it for a security portal site), so it was an obvious feature to add. But I don\'t think a lot of people really use it these days ...
