Oh that's interesting, he's expanded the free licenses.  Still though,
while OCB is very clever and it was important as the first satisfactory
AEAD mode, I don't think it's that important these days.  GCM is
standardized, does similar things, and while it's potentially slower,
some CPUs even have hardware support for it now.  If you library doesn't
support GCM (I haven't checked yet) then it probably should.
