crng

crng

Generate random values from a cryptographicaly-secure random number generator in Node.js. Uses the crypto module.

Generators

cryptoRandom01

Generate a value between 0 (inclusive) and 1 (exclusive).

import {cryptoRandom01} from "crng";
// const {cryptoRandom01} = require("crng");

let val: number = cryptoRandom01();

cryptoRandomDouble

Generate a number that is not infinite and not NaN.

import {cryptoRandomDouble} from "crng";
// const {cryptoRandomDouble} = require("crng");

let val: number = cryptoRandomDouble();

cryptoRandomHex

Generate a string containing hexadecimal characters with n bytes of entropy (defaults to 8).

Note that the length of the resulting value is double the entropy amount.

import {cryptoRandomHex} from "crng";
// const {cryptoRandomHex} = require("crng");

let val: string = cryptoRandomHex(8);
console.assert(val.length === 16);
