I thought SRP6 was patented. Isn't SRP6 patented?
Yes, here an excerpt from http://srp.stanford.edu/licence.txt
SRP is royalty-free worldwide for commercial and non-commercial use.
The SRP library has been carefully written not to depend on any
encumbered algorithms, and it is distributed under a standard
BSD-style Open Source license which is shown below. This license
covers implementations based on the SRP library as well as
independent implementations based on RFC 2945.
The last sentence seems the key,
one problem seems to be a vague patent claim from Phoenix Technologies
see http://www.ietf.org/ietf/IPR/PHOENIX-SRP-RFC2945.txt
(or the same discussion on openssh-unix-dev
