Protected Methods

Method	Description
checksum ( string $cyphertext, string $iv, string $key, string $cipher = 'rijndael-128', string $mode = 'cbc', string $algo = 'sha256' ) : string	Create a message authentication checksum.
checksumVerify ( string $calculated, string $supplied )	Verify checksum during decryption step and throw error if mismatching.
key ( string $password, string $iv, integer $cost, string $cipher = 'rijndael-128', string $mode = 'cbc', string $algo = 'sha256' ) : string	Transform password into key and perform iterative HMAC (if specified)

Method	Description
hashNormalize ( string $hash, integer $size, string $algo ) : string	This will normalize a hash to a certain length by extending it if too short and truncating it if too long. This ensures that any hash algo will work with any combination of other settings. However, it is probably best to make sure that the keysize and algo size are identical so that the input hash passes through unchanged.

Create a message authentication checksum.

protected static checksum ( string $cyphertext, string $iv, string $key, string $cipher = 'rijndael-128', string $mode = 'cbc', string $algo = 'sha256' ) : string

$iv	string	Initialization vector.
$key	string	HMAC key
$cipher	string	Cipher string
