cryptohash-sha256: Fast, pure and practical SHA-256 implementation

[ bsd3, cryptography, data, library ] [ Propose Tags ]

A practical incremental and one-pass, pure API to the SHA-256 cryptographic hash algorithm according to FIPS 180-4 with performance close to the fastest implementations available in other languages.

The core SHA-256 algorithm is implemented in C and is thus expected to be as fast as the standard sha256sum(1) tool; for instance, on an Intel Core i7-3770 at 3.40GHz this implementation can compute a SHA-256 hash over 230 MiB of data in under one second. (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-256 hash algorithm without any dependencies on packages other than base and bytestring. The API exposed by cryptohash-sha256-0.11.*'s Crypto.Hash.SHA256 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 cryptohash-0.11.7's Crypto.Hash.SHA256 module, though with a clearly smaller footprint by almost 3 orders of magnitude.
