Thanks for your interest!

Erm, I didn't plan that atm, but might be a nice idea. Will have to
look up their API and brush my code up "a bit". My interface is just
written to keep up with the "strange" bitlength of ECC-curves, like
NIST-P521 (that is no typo, it is _not_ 512bit), NIST-P244, NIST-P571
etc., so I see it as not directly fitting to use size-of-2-length
Datatypes. That might give some speedup at the cost of wasting space,
but I haven't tried it.

Yeah, it's the MIT X11 License and by the virtue of that it grants for
all practical purposes the same rights as the BSD3, but there is no way
to mix it up with the BSD4, which is the reason I chose it.
