BLAKE2 is an improved version of BLAKE, one the finalists in the NIST SHA-3 competition. Like BLAKE or SHA-3, BLAKE2 offers the highest security, yet is fast as MD5 on 64-bit platforms and requires at least 33% less RAM than SHA-2 or SHA-3 on low-end systems. This implementation uses the BLAKE2b variant of the algorithm which is optimized for 64-bit systems. The algorithm was designed by Jean-Philippe Aumasson, Samuel Neves, Zooko Wilcox-O'Hearn, and Christian Winnerlein.

You may need to restart your web server to load the extension.
string blake2 ( string $str [, int $outputSize = 64, string $key, bool $rawOutput = false ] )
-
$str: The string to hash
-
$outputSize: The length of the output hash (can be between 1 and 64)
-
$key: Turns the output into a keyed hash using the specified key
-
$rawOutput: If set to true, then the hash is returned in raw binary format
-
Return value: A hex string containing the BLAKE2 hash of the input string
string blake2s ( string $str [, int $outputSize = 32, string $key, bool $rawOutput = false ] )
-
$str: The string to hash
-
$outputSize: The length of the output hash (can be between 1 and 32)
-
$key: Turns the output into a keyed hash using the specified key
-
$rawOutput: If set to true, then the hash is returned in raw binary format
-
Return value: A hex string containing the BLAKE2s hash of the input string
