A practical incremental and one-pass, pure API to the
<https://en.wikipedia.org/wiki/SHA-1 SHA-1 hash algorithm> (including
<https://en.wikipedia.org/wiki/HMAC 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
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
