ghc-cryptohash-sha256


Fast, pure and practical SHA-256 implementation


Unspecified

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

  • HMAC-SHA-256: SHA-256-based [Hashed Message Authentication

Codes](https://en.wikipedia.org/wiki/HMAC) (HMAC) - HKDF-SHA-256: HMAC-SHA-256-based Key Derivation Function (HKDF)

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.
