isaac.js - NodeJS compatibility version

isaac.js is a JavaScript implementation of the ISAAC random number generator.

ISAAC is a CSPRNG designed by Robert J. Jenkins Jr. in 1996 and based on RC4. It is designed to be fast and secure.

isaac.js is fully compatible with the other 32-bit integer arithmetic implementations of ISAAC and can be used as a good alternative to the default javascript Math.random() function.

Use

npm install isaac

var isaac = require( 'isaac' );

Then just call isaac.random() to get a random real number between 0.0 and 1.0 : var random_number = isaac.random( );

If you want a little more control over the PRNG you can reset isaac (all internals to zero) using isaac.reset() or use a new seed using isaac.seed(s) (s can be a string, a number or an array of number). You can also run the PRNG an arbitrary number of time before querying a new random output using isaac.prng(n), where n (optional) is the number of run. isaac.rand() allow you to get a random 32-bit integer between -2147483648 (0x00000000) and 2147483647 (0xFFFFFFFF).
