mhash_keygen_s2k()

Syntax
string mhash_keygen_s2k (
int $hash,
string $password,
string $salt,
int $bytes)
Arguments
- hash - The hash id used to create the key. One of the MHASH_XXXconstants.
- password - User supplied password.
- salt - Must be different and random enough for every key you generate in order to create different keys. That salt must be known when you check the keys, thus it is a good idea to append the key to it. Salt has a fixed length of 8 bytes and will be padded with zeros if you supply less bytes.
- bytes - The key length, in bytes.
Description
Generates a key according to the hash given a user provided password.

PHP 4.0.4, 5
Return value
Returns the generated key as a string, or FALSE on error.
