 Two PRNGS are provided:
 * `Splitmix`, as described in the paper [_Fast Splittable Pseudorandom Number Generators_](http://gee.cs.oswego.edu/dl/papers/oopsla14.pdf) by Guy L. Steele Jr., Doug Lea, and Christine H. Flood, published in the proceedings of OOPSLA 2014.
-* `Chacha`, which is based on the [Chacha stream cipher](https://cr.yp.to/chacha.html) by D. J. Bernstein. Splitting is implemented by "jumping", i.e. randomly generating a 128-bit initial state for the new PRNG using the current PRNG.

 Both PRNGs pass the [Dieharder](http://webhome.phy.duke.edu/~rgb/General/dieharder.php) statistical randomness test.
