+Name:                cprng-aes
+Version:             0.6.1
+x-revision: 1
+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).
