# isaac

Nim implementation of [ISAAC](http://www.burtleburtle.net/bob/rand/isaacafa.html) -

a cryptographically secure PRNG.

API:

```nim

type IsaacGenerator* = ref object

proc newIsaacGenerator*(seed: array[256, uint32]): IsaacGenerator

  ## Initializes and returns ISAAC PRNG instance.

  ## Make sure the seed is an array of *true random values* obtained from a

  ## source like urandom. Otherwise, security of the algorithm is compromised.

proc nextU32*(generator: IsaacGenerator): uint32

  ## Returns the next generated 32-bit value

proc randomUint32*(generator: IsaacGenerator): uint32

  ## Alias for ``nextU32``. Added for compatibility with nim-random library.

```
