Yes this is the branch and sorry for any inconvenience this might have
caused to you. I'm working on this branch but due to my very limited
free time I couldn't safely merge with the rest of the code. I plan to
do it this weekend.

Probably I missed this email. Sorry again for any inconvenience.

Could be. I only kept the ones that are used for gnutls because I wanted
to avoid having the symmetric encryption. It seems we now with your
patch need it. Please feel free to reintroduce it.

Does it work without any additions to this branch?

I just run
autoreconf -fvi
./configure
and make
