I'm the inventor of SRP. The version of the protocol described in RFC
2945 (see http://srp.stanford.edu/) is royalty-free for worldwide use.
David Jablon is the inventor of SPEKE. Visit his website
(http://www.integritysciences.com/) for licensing information.
You should be able to contact the inventors of the other password
protocols (AMP, PAK, S3P, SNAKE, etc.) through links on my site or David
Jablon's site.
