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..

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.
