ghc-cprng-aes 0.6.1 Crypto Pseudo Random Number Generator using AES in counter mode in Haskell

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.

  • Arithmbetic 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).
