that is interesting, but does not hurt my tool too much, because my whitener does chain blocks. i use a keccak sponge that is never cleared or reset. even if you feed it with all zeros, the output is indistinguishable from random for a very long time. > It would be much better to implement a multi-stage entropy pool design certainly, but such tools have their purpose. for example a online lotteries might want to have high throughput random number generator. if you really feed some visual noise to a camera, the entropy production can even be multiple megabytes per second. it dwarfs any randomness harnessed from a regular desktop.
