-		The KMS v4 hash is a variant of CMAC-AES-128. There are two key differences:
-		* The 'AES' used is modified in particular ways:
-		  * The basic algorithm is Rjindael with a conceptual 160bit key and 128bit blocks.
-		    This isn't part of the AES standard, but it works the way you'd expect.
-		    Accordingly, the algorithm uses 11 rounds and a 192 byte expanded key.
-		* The trailing block is not XORed with a generated subkey, as defined in CMAC.
-		  This is probably because the subkey generation algorithm is only defined for
-		  situations where block and key size are the same.
