Did the RSA implementation change significantly in 2.x?

No, it used an own algorithm, BassOmatic, but unfortunately it proved to be flawed.

Would it? If someone would write GnuPG plugins for the BassOmatic cipher of pgp 1 and an MD4 hash plugin, would GnuPG then be able to decrypt and verify pgp 1.0 messages? What I see from the pgp 1 documentation is that the basic structure (pubkey algo to encrypt session key of symm algo) did not change since pgp 1.0. -- ir. J.C.A.
