init method
Init the MAC with its initialization params
. The type of
CipherParameters depends on the algorithm being used (see
the documentation of each implementation to find out more).
Implementation
@override

} else if (params is KeyParameter) {
final zeroIV = Uint8List(params.key.length);
_params = ParametersWithIV(params, zeroIV);
}
