BLAKE2s Luau

A pure Luau implementation of the BLAKE2s hashing algorithm. Blazing fast (for Luau) and well-tested.

API

This module returns a single function with the following type signature:

``
blake2s(message: string, hashLen: number, key: string?): string
`

The message passed to this function will be hashed using BLAKE2s. The returned hash will be hashLen bytes in length.
If provided, key` will be used as a [pepper][Pepper] for the algorithm.
