fast, pure and practical SHA-256 implementation
A practical incremental and one-pass, pure API to the SHA-256 hash
algorithm (including HMAC support) with performance close to the
fastest implementations available in other languages.

The implementation is made in C with a haskell FFI wrapper that
hides the C implementation.
