Description:
------------
i wish for blake2b to be natively supported in PHP, the TL;DR is that it's an excellent replacement for the broken SHA1, being faster and more secure. longer version:


BLAKE2b is a very fast cryptographically secure hash function (faster than sha1/md5, which themselves are considerably faster than sha2/sha3, but sha1 & md5 is broken), provides security superior to SHA-2 and similar to that of SHA-3, and it's predecessor (blake) was a SHA-3 finalist in the competition to become the SHA-3 standard, you can read more about it at https://blake2.net/


(one more thing, blake2b supports variable output sizes between 1-64 bytes inclusive, but the de-facto output size is 64 bytes. while an argument could be made for supporting a "blake2b,10" syntax for output size, i think such a feature should get it's own dedicated feature request, that would prove that anyone is actually interested other sizes, i am not.)

Test script:
---------------
<?php

var_dump(hash("blake2b", "test", false));

Expected result:
----------------
string(128) "a71079d42853dea26e453004338670a53814b78137ffbed07603a41d76a483aa9bc33b582f77d30a65e6f29a896c0411f38312e1d66e0bf16386c86a89bea572"

Actual result:
--------------
Warning: hash(): Unknown hashing algorithm: blake2b in /in/IJHSi on line 3
bool(false)
