We have been asked by a customer if we have any tests that demonstrate the randomness of the SSLeay random number generator (augmented by some sound-card random number seeding that we wrote).
I'd like to find some standard implementation for testing randomness, but Schneier offers no help (other than a reference to Knuth Vol 2), and I don't know where else to turn.
I realise that cryptographic randomness requires unpredictability, and this quality depends upon closed-world assumptions about unknown individuals' predictive powers, but we have to live with that.
You mean you don't have a copy of Knuth, Vol 2. For shame! I'm too lazy to look it up for you, but I believe the two tests are called the Run test and the Chi-square method. (trying to remember from my own dusty compSci memories) jim
