Synopsis

Principled, portable & extensible hashing of data and types, including an implementation of the FNV-1a and SipHash algorithms.

Description

This package is a rewrite of the hashable library by Milan Straka and Johan Tibell, having the following goals:

• Extensibility; it should be easy to implement a new hashing algorithm on any Hashable type; in this package we provide SipHash and FNV-1a.

• Honest hashing of values, and principled hashing of algebraic data types (see e.g. hashable issues #74 and #30)

• Cross-platform consistent hash values, with a versioning guarantee. Where possible we ensure morally identical data hashes to indentical values regardless of processor word size and endianness.

• Make implementing identical hash routines in other languages as painless as possible. In addition to SipHash, we provide an implementation of a simple hashing algorithm (FNV-1a) and make an effort to define Hashable instances in a way that is well-documented and sensible, so that e.g. one can easily implement a string hashing routine in JavaScript that will match the way we hash strings here.

Versioning: Except for instances where we specifically note that we make no promise of consistency, changes to hash values (and consequently changes to StableHashable values, where applicable) entail a major version number bump.
