#219 This implementation of HC-128 does not yet have the test vectors. HC-256 was using a table size of 2660 instead of 2560, this does not cause issue with the generated key stream, but slightly lengthens the initialization time. The function
h2in HC-256 usedself.ptableinstead ofself.qtable, this means that it does not apply linear masking when the stream is usingh2. For inputs that never get output fromh2it gives the correct results, but onceh2is in use the values are incorrect.
