hash_hmac
Synopsis
hash_hmac(string, string, string, bool ...): string
- Area
Runtime\PS\Crypto\Hash\hash_hmacareas
Description
hash_hmac returns the $algo keyed digest of $data under $key as lowercase hex characters, or as raw bytes when $binary is true; a key longer than the algorithm's block size is itself digested first, which is HMAC's own rule and not a choice made here.
Usage
$value = hash_hmac($arguments);
$fn = hash_hmac(...);
