Metadata revisions for cryptohash-sha256-0.11.101.0

Package maintainers and Hackage trustees are allowed to edit certain bits of package metadata after a release, without uploading a new tarball. Note that the tarball itself is never changed, just the metadata that is stored separately. For more information about metadata revisions, please refer to the Hackage Metadata Revisions FAQ.

  • Changed description from

    A practical incremental and one-pass, pure API to
    the [SHA-256 cryptographic hash algorithm](https://en.wikipedia.org/wiki/SHA-2) according
    to [FIPS 180-4](http://dx.doi.org/10.6028/NIST.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](https://linux.die.net/man/1/sha256sum);
    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](https://hackage.haskell.org/package/SHA).)
    
    
    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](https://en.wikipedia.org/wiki/HKDF) (HKDF)
    
    conforming to [RFC6234](https://tools.ietf.org/html/rfc6234), [RFC4231](https://tools.ietf.org/html/rfc4231), [RFC5869](https://tools.ietf.org/html/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](https://www.reddit.com/r/haskell/comments/5lxv75/psa_please_use_unique_module_names_when_uploading/dbzegx3/).
