Computes hash

Function-8-1-0

Description

mhash(int $algo, string $data, string|null $key = null): string|false

mhash() applies a hash function specified by algo to the data.

algo: The hash ID. One of the MHASH_hashname constants.
data: The user input, as a string.
key: If specified, the function will return the resulting HMAC instead. HMAC is keyed hashing for message authentication, or simply a message digest that depends on the specified key. Not all algorithms supported in mhash can be used in HMAC mode.

Returns the resulting hash (also called digest) or HMAC as a string, or false on error.

Version	Description
