Simple crypto pseudo-random-number-generator with really good randomness property.
Using ent, a randomness property maker on one 1Mb sample:
Entropy = 7.999837 bits per byte.
Optimum compression would reduce the size of this 1048576 byte file by 0 percent.
Chi square distribution for 1048576 samples is 237.02
Arithmetic mean value of data bytes is 127.3422 (127.5 = random)
Monte Carlo value for Pi is 3.143589568 (error 0.06 percent)
Compared to urandom with the same sampling:
Entropy = 7.999831 bits per byte.
Optimum compression would reduce the size of this 1048576 byte file by 0 percent.
Chi square distribution for 1048576 samples is 246.63
Arithmetic mean value of data bytes is 127.6347 (127.5 = random).
Monte Carlo value for Pi is 3.132465868 (error 0.29 percent).
