Module documentation for 0.11.100.1
A practical incremental and one-pass, pure API to the SHA-512 cryptographic hash algorithm 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
HMAC-SHA-512: SHA-512-based Hashed Message Authentication Codes (HMAC)
conforming to RFC6234, RFC4231, RFC5869, et al..
Packages in the
Relationship to the
cryptohash package and its API
This package has been originally a fork of
cryptohash-0.11.7 because the
package had been deprecated and so this package continues to satisfy the need for a
lightweight package providing the SHA-512 hash algorithm without any dependencies on packages
bytestring. The API exposed by
Crypto.Hash.SHA512 module is guaranteed to remain a compatible superset of the API provided
cryptohash-0.11.7's module of the same name.
Consequently, this package is designed to be used as a drop-in replacement for
Crypto.Hash.SHA512 module, though with
a clearly smaller footprint by almost 3 orders of magnitude.
