squares-rnd

Simple and fast counter based non-crypto random generator.

The algorithm is based on Middle Square Weyl Sequence RNG. See paper for details.

NOTE: Not cryptographically secure.

There are several note-worthy properties to the algorithm:

• State is represented by counter, which is incremented to produce new value, hence making it easy to predict how state would change.
• The code is short and simple, only taking minimum amount of operations to produce uniform output.
• key must have close to equal number of zeroes and ones for optimal output. This crate provides single key for use, to have more see gist
