RE: WTLS implementation status (restrictions of RSA) ?

The RSA patent expired in 2000. The algorithm is
in the public domain now (RSA Inc. released it into the
public domain a few weeks before the patent expired).

See: http://www.rsasecurity.com/news/pr/000906-1.html

However the RC5 algorithm is still patented.

yes, currently it's the only "supported" configure option flag for
--with-wlts. But hey, it's currently ony in the state to compile
cleanly, I'm not aware how far Nick did get when implementing this,
Nick?!

You mean patent issues?! Hmmm, what do the others think about this?

you can configure using ./configure --with-wtls=openssl, but you can't
*use* it. We need to addopt 3ui.com's wtlsbox for this, and
unfortunatly no one is (or seems) currently working on this. It's on
top of my TODO list, but I can put my hands on it for the next 2
weeks.

Any volonteers with OpenSSL knowledge?!
