Expand description

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 download key file gist

Structs

  • Rand
    Stateful representation of algorithm.
  • RandRes
    Full rand result

Constants

  • KEY
    Default key to be used with algorithm
