# mhash

(PHP 3>= 3.0.9, PHP 4 )

mhash -- Compute hash

## Description

string mhash ( int hash, string data [, string key])

mhash() applies a hash function specified by `hash` to the `data` and returns the resulting hash (also called digest). If the `key` is specified it will return the resulting HMAC. 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. In case of an error returns `FALSE`.
