I did a test with the contact, and I received this response:

So it seems to work, but I do have this concern: is it possible that since
they tested it on Windows with GnuPG and not on their e-Business server on
the mainframe and that the real file will fail when their mainframe attempts
to decrypt it? I sent this reply to get that extra test done:

Is that correct? When I view the encrypted file, it shows this:
public key encrypted packet: version 3, algo RSA, keyid <blahblah>
encrypted data packet: mdc method 0, length 82.
What is mdc method 0?
My concern is partially due to this entry on
Wikipedia , which seems to imply that the development for e-Business server
stopped in 2001, which means that it may fall under the heading of "legacy
PGP program" that is not OpenPGP conformant and therefore can't decrypt the
