The PGP 3.0 code that I've been working on has support for: IDEA, 3DES MD5, SHA1 RSA, DSS, ElGamal It does not discontinue support for the PGP 2.6.2 algorithms. It adds support for new ones. -derek

I hope that in version 4.0, after the users had time to migrate to DSS/ElGamal, PGP will fully move away from RSA. --Lucky

Personally, I'd prefer it if crypto applications had wide support, user selectable, for as many methods as possible.

What do you mean? 3DES ships with Stronghold, and will ship with C2Net's other products as well. -- Sameer Parekh Voice: 510-986-8770 President FAX: 510-986-8777 C2Net http://www.c2.net/ sameer@c2.net

Chaum has something called unanticipated blind signatures that don't use RSA. The problem with blinding is not the RSA patents. Those run out much sooner than Chaum's patents.

Yes, but you still need to license the blind signature patent itself. --Lucky

Note that part of my above post is now in need of revision as a result
of comments I received from that post. PGP 3.0 will, it seems, still
be able to verify (and maybe even generate too?) RSA signatures, and
decrypt RSA encrytped email. So the "will not use RSA" above is
incorrect.
