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.
- Windows/Linux.
// 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()))
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] .
- 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.
