IIRC, a GPG message in encrypted only once - even if there's multiple recipients. It goes like this: 1.) A random key is generated. 2.) The message is encrypted with that random key, plugged into a symmetric cipher. 3.) That random key is encrypted with the public key of each recipient, and appended to the message itself. So, the recipient would reverse that process: Use their private key to decrypt the random key, and use that in the appropriate symmetric cipher to decrypt the message. - -- F.
