BLAKE2 hash function

Implementing “Blake2b” as described in RFC7693

Note that, at present, this only supports full message hashing and no OPTIONAL features of BLAKE2.

Summary

Blake2b hashing

Note that the output_size is in bytes, not bits

  • 64 => Blake2b-512 (default)
  • 48 => Blake2b-384
  • 32 => Blake2b-256

Per the specification, any output_size between 1 and 64 bytes is supported.
