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.
