ghc-cryptohash-sha1

Fast, pure and practical SHA-1 implementation

A practical incremental and one-pass, pure API to the <<a href="https://en.wikipedia.org/wiki/SHA-1">https://en.wikipedia.org/wiki/SHA-1</a> SHA-1 hash algorithm> (including <<a href="https://en.wikipedia.org/wiki/HMAC">https://en.wikipedia.org/wiki/HMAC</a> 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 SHA1 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.SHA1" module, though with a clearly smaller footprint.
