-- Cryptohash API exported through crypto-api.
--
-- Note: Current version (0.10) of crypto-api suffers a small performance problem.

-- Hopefully, future versions will fix this.

-- need to redefine a context wrapper to not clash with the already existing

--
-- unfortunately haskell uses cpp in traditional mode to avoid problem, but traditional mode
-- doesn't do proper token concatenation, so need to define the ctxname in the macro
