Have your tried the master branch? SHA2 has been added there. I'm
looking into  support for the non-standard AES protocols. They will
likely be off by default and require a configure option to enable.

Luckily we are starting to ramp up for a new release cycle. You can
help by trying the master branch. I'll get back with you on the new
AES stuff after I've had time to review your patch.
