Uh, AFAIK with GPG, I have a keypair. Other people sign it, so people
who see the signature can trust that it is mine. So the private key I
use to decrypt should correspond to a public key signed by other people.
How else would others know that the key they use to encrypt is mine, and
assume that only I can decrypt it?
