Public Methods

Method	Description
ihmac ( string $data, string $key, integer $iter, string $algo = 'sha256' ) : string	Perform a raw iterative HMAC operation with a configurable algo.
make ( string $input, string $password, integer $cost = 250000 ) : string	Hash an input string into a salted 512 byte hash.
verify ( string $input, string $hash, string $password ) : boolean	Check the validity of a hash.

Method	Description
build ( string $input, string $password, integer $cost, string \| null $salt = null ) : string	Internal function used to build the actual hash.
cost ( integer $cost ) : integer	Return a normalized cost value.
costHash ( $cost, $salt, $password )

This class always performs at least one hash to prevent the input from being passed back unchanged if bad parameters are set.

public static ihmac ( string $data, string $key, integer $iter, string $algo = 'sha256' ) : string
$data	string	Data to hash.
$key	string	Key to use to authenticate the hash.
$iter	integer	Number of times to iteratate the hash
$algo	string	Name of algo (sha256 or sha512 recommended)
return	string

Hash an input string into a salted 512 byte hash.

public static make ( string $input, string $password, integer $cost = 250000 ) : string
$input	string	Data to hash.
$password	string	HMAC validation password.
$cost	integer	Cost value of the hash.
return	string

Check the validity of a hash.

public static verify ( string $input, string $hash, string $password ) : boolean
$input	string	Input to test.
$hash	string	Known hash to validate against.
$password	string	HMAC password to use during iterative hash.
return	boolean
