You and your friend Alice get together and sign each others keys in person. Later, Bob sends you a key of his, signed by Alice. Since you know Alice's key to be valid, you suspect that Bob's is. This way, a small number of people you trust can validate a large number of other people who you can't meet in person. I'd just read the manual. Most questions are answered. -- Perry Metzger pmetzger@shearson.com -- Just say "NO!" to death and taxes. Extropian and Proud.
