We need this (or a variant) for OpenPGP as well, by Sergi Blanch i Torne,
(sergi at calcurco dot org) is working on that.

I am not sure whether whether the current API is okay, thus I hesitate
to publish it.

Yes. There is the potential patent problem of course. FWIW, RedHat
removed all ECC code from Lobgcrypt.

I noticed :-)

I also though of that when I wrote an ssh library but came to the
conclusion that we need to exchnage too much data in a very portable
way. In the end such an abstract interface would be too complex.
Die Gedanken sind frei. Auschnahme regelt ein Bundeschgesetz.
