A practical incremental and one-pass, pure API to the
<https://en.wikipedia.org/wiki/SHA-2 SHA-256 hash algorithm>
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@ 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.
