Don,
Just an addition doesn't work.
In fact if you read well you'll see that Shawul didn't believe initially a multiplication would work...

You are trolling now ... Multiplication works fine but only questioned the quality of the keys as the low order bits contain too many zeros. So does the higher bits as I have shown with 10 million trials. I thought that was interesting and suggested "addition" to cure just that. Whats the problem now ?
Please stop trolling or go away.


It was me who suggest that a combination using multiplication would work, yet would be too slow.

Throughput latency, we aren't even looking to total latency, of multiplication is 3.75 clocks at intel cpu's.

Therefore the proposal to use what RanRot is using to generate random numbers, namely a combination of 2 rotations with 1 addition, that's a lot faster than doing a multiplication.

Accusing me of trolling is not a good habit.
