Description Author

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 Blake2 algorithm like: 2s, 2b and XOF.

The algorithm also takes as parameters a salt value and personalization strings.

Nominee
Vote		 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 2 hashing algorithm.

Included BLAKE2s, BLAKE 2b & BLAKE2XOF (modes 2b,2s & XOF 0)

Examples:

$data = ""; $key = ""; $salt = ""; $Personalization = "";

$b2 = new BLAKE2s($key,$salt,$Personalization); echo $b2->hash($data);

$b2 = new BLAKE2b($key,$salt,$Personalization); echo $b2->hash($data);

Extended hashes:

$b2 = new BLAKE2XOF("2s",$key,$salt,$Personalization); echo $b2->hash($data,XOF length);

$b2 = new BLAKE2XOF("2b",$key,$salt,$Personalization); echo $b2->hash($data,XOF length);

$b2 = new BLAKE2XOF("2s",$key,$salt,$Personalization); echo $b2->hash($data,0);

$b2 = new BLAKE2XOF("2b",$key,$salt,$Personalization); echo $b2->hash($data,0);
