math/dieharder 3.31.1p2 OpenBSD

Dieharder is a random number generator (rng) testing suite. It is intended to test generators, not files of possibly random numbers.

dieharder is a tool designed to permit one to push a weak generator to unambiguous failure (at the e.g. 0.0001% level), not leave one in the "limbo" of 1% or 5% maybe-failure. It also contains many tests and is extensible so that eventually it will contain many more tests than it already does.
