A class for calculating message digests using the BLAKE3 hash function, by Jack O'Connor, Jean-Philippe Aumasson, Samuel Neves, and Zooko Wilcox-O'Hearn.

BLAKE3 produces a digest of 256 bits (32 bytes) by default.

Examples

require 'digest'

Compute a complete digest

Digest::BLAKE3.hexdigest 'abc' #=> "6437b3ac38465133ffb63b75273a8db548c558465d79db03fd359c6cd5bd9d85"

Compute digest by chunks

blake3 = Digest::BLAKE3.new # =>#Digest::BLAKE3 blake3.update "ab" blake3 << "c" # alias for #update blake3.hexdigest # => "6437b3ac..."

Use the same object to compute another digest

blake3.reset blake3 << "message" blake3.hexdigest
