That is correct.  PGP 5 deprecated RSA keys in favor of Diffie-Hellman (DH)
keys, and PGP 6 does not grok RSA at all.  RSA is patented, and has an
extremely restrictive use license, whereas the DH patent has expired and is
now public domain.  Likewise, PGP 5 deprecates IDEA in favor of 3DES.

GnuPG, being free software, cannot use RSA or IDEA because of patent and
license restrictions[1].  So it is probably time for you to bite the bullet
and generate a DH key for yourself.


[1] There are RSA and IDEA modules for GnuPG, but the former cannot be used
in the US, and neither are free which is why they are not distributed with
GnuPG.
