You don't give someone your name, you give them an 80-bit key
fingerprint. It looks something like m-NN4H-JS7Y-OTRH-GIRN. The m- is
common to all, it just says this is one of that sort of hash.
1. And they run away screaming.
2. It only takes 2^50 trials to come up with a valid fingerprint that
agrees with your fingerprint except at four non chosen places.
