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.
NOTE This package has been forked off cryptohash-0.11.7 because the cryptohash package has been deprecated and so this package continues to satisfy the need for a lightweight package providing the SHA256 hash algorithm without any dependencies on packages other than base and bytestring.
Consequently, this package can be used as a drop-in replacement for cryptohash’s Crypto.Hash.SHA256 module, though with a clearly smaller footprint.
