rdrand-lite v1.4.11

rdrand-lite.js

The Intel CPU has a TRNG instructions called RDRAND/RDSEED. You can generate a good-random numbers without any external, expensive hardware. This NPM module enables you to use those instructions from Node.js, applicable for simulation, analysis, games, or anything you want.

• Out of the box : No need to install additional build tools.

API

// node.js
const rng = require('rdrand-lite');

//and then

console.log(rng.rdRand32())
console.log(rng.rdRand64())
console.log(rng.rdSeed32())
console.log(rng.rdSeed64())
console.log(rng.normalizeUint32(rng.rdSeed32()))
console.log(rng.normalizeUint64(rng.rdSeed64()))

Basic API

• rng.isRrdrandSupported(): number - If 1 is returned, it indicates support for rdrand.
• rng.rdRand32(): uint32 - returns uint32; ramdom binary bits by rdrand.
• rng.rdRand64(): uint64 - returns uint64; ramdom binary bits by rdrand.
• rng.rdSeed32(): uint32 - returns uint32; ramdom binary bits by rdseek.
• rng.rdSeed64(): uint64 - returns uint64; ramdom binary bits by rdseek.
• rng.normalizeUint32(uint32): number - returns 0, 1 .
• rng.normalizeUint64(uint64): number - returns 0, 1 .

What is the difference between RDSeed and RDRand:

• A pseudorandom generator that's periodically seeded from that noise source, whose output is available through the RDRAND instruction;
• A true random generator that's driven off the noise source, whose output is available through the RDSEED instruction.
