It probably does, actually; PGP just, for marketing reasons, calls it
Diffie-Hellman/DSS.  (Long story, but yes, they're the exact same thing.)

That said, your customer does not appear to understand how GnuPG or PGP
work.  _All_ OpenPGP-conformant applications (GnuPG, PGP, and others)
can handle 3DES; and 3DES has absolutely nothing to do with how you
generate your public key.
