%description
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).
