Sure: you're probably just getting a real public key that's being regenerated from the secret key. With most (if not all) public key algorithms used by PGP/GPG, the public key can be made with minimal effort from the secret key (whereas the converse is not true--the public key cannot be made from the secret key). I know this is true for RSA and RSA-like algorithms, and I believe it's true with Diffe-Hellman (and variants like ElGamal). - -- Wesley J.
