This class can generate hashes of data using the Blake2 algorithm.

It can take a data string and a key and it generates a hash using any of the supported modes of the Blake3 algorithm.

Currently it supports hashing modes like: HASH, KEYED and DERIVE with XOF output.

Blake is a hashing algorithm used to create hash values from sets of data.

The hash values can be used to verify if a given data block was modified during an eventual security attack.

Such security attacks are usually aimed to alter data or programs that could make them work in a dangerous way for the users that receive that data or programs.

This package provides a pure PHP solution to implement the Blake 3 hashing algorithm.

PHP Blake3 hash,keyed_hash,derive_key,XOF PHP implementation of BLAKE3

It supports HASH, KEYED and DERIVE modes with XOF output

There is a python version

which is 2.5x slower than this implementation in generating the hash

This implementation have been checked with the test vectors provided

By default, XOF output are 32 bytes

Examples of use:


	$b2 = new BLAKE3();		
	$hash = $b2->hash($h,$xof_length);


	$b2 = new BLAKE3($key);		
	$keyed_hash = $b2->hash($h,$xof_length);


	$b2 = new BLAKE3();		
	$derive_key = $b2->derivekey($context_key,$context,$xof_length);
