Depends on 2 packages(full list with versions):

Used by 1 package in nightly-2022-09-26(full list with versions):

crypt-sha512

A practical incremental and one-pass, pure API to the SHA-512 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 SHA512 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.SHA512 module, though with a clearly smaller footprint.
