Fast, pure and practical SHA-512 implementation
A practical incremental and one-pass, pure API to the
SHA-512,
SHA512/t and SHA-384 cryptographic hash algorithms according to
FIPS 180-4 with performance close to the fastest
implementations available in other languages.
The core SHA-512 algorithm is implemented in C and is thus expected to
be as fast as the standard
sha512sum(1) tool. (If, instead, you
require a pure Haskell implementation and performance is secondary,
please refer to the
SHA package.)
Additionally, this package provides support for
conforming to
RFC6234,
RFC4231,
RFC5869, et al..
Packages in the cryptohash-* family
Relationship to the cryptohash package and its API
This package has been originally a fork of
cryptohash-0.11.7
because the
cryptohash package had been deprecated and so
this package continues to satisfy the need for a lightweight package
providing the SHA-512 hash algorithms without any dependencies on
packages other than
base and
bytestring. The API
exposed by
cryptohash-sha512-0.11.*'s
Crypto.Hash.SHA512,
Crypto.Hash.SHA512t, and
Crypto.Hash.SHA384 module is guaranteed to remain a compatible
superset of the API provided by the
cryptohash-0.11.7's
module of the same name.
Consequently, this package is designed to be used as a drop-in
replacement for the
cryptohash-0.11.7 modules mentioned
above, though with a
clearly smaller footprint by almost 3 orders
of magnitude.
