Hi,
according to E.Rescorla: "SSL and TLS" ISBN 0-201-61598-3 p.53 OpenSSL
is free for commercial and noncommercial use (BSD-style license). RSA`s
patent expired in September 2000. As of the direction, I would prefer
J.Menezes: "Handbook of Applied Cryptography" ISBN 0-8943-8523-7.
Regards,

I would direct you to Schneier ("Applied Cryptography") for patents
related to things that were known in 1996, including elliptic curve.
None of us on the list are lawyers, and we certainly haven't done an
exhaustive patent search.

Hello,
I am currently looking into what configuration of openssl that would be
patent infringement safe world wide. This is what come up with so far.
IDEA should be left out, Ascom holds a patent for this algorithm.
RC5 should be left out. RSA security holds a patent for this algorithm
MD2, MD4 and MD5 are ok to use. RSA Security has published an IPR disclosure
on www.ietf.org stating that these algorithms can be made, used and sold
without any license from RSA Security Inc.
Is RSA ok to include? The RSA patent has expired in the US, but what about
other countries?
What about eliptic curves? I have found some discussions on emailing lists
about Sun's eliptic curve contribution to Openssl and possible IPR issues?
What is the status?
Are there other patents or other IPR issues that needs to be considered?
Regards Roger
