    You are refering to the 2nd part of crypting: signature.
    Crypting to your key is only to ensure that you'll be the only one to read it, \
but you are supposed to know what you'll find in the message.  Signing is dedicated \
to the receipient: it allows him to be sure that the message comes from exactly you.
