Readme

random-poly-fill
A polyfill for crypto.randomFill and crypto.randomFillSync from Node.js core.
These two functions were added in Node.js v6.13.0. Use this polyfill if you need to use these function in older versions of Node.js.
This polyfill is not optimized for speed or low resource usage. If you can, use crypto.randomBytes directly instead.
npm build status js-standard-style

Installation

npm install random-poly-fill --save

Usage

const { randomFill, randomFillSync } = require('random-poly-fill')

const source = Buffer.alloc(10)

randomFill(source, 0, 5, function (err, target) {
  if (err) throw err
  console.log(source.toString('hex')) // fc4584c64a0000000000
  console.log(target.toString('hex')) // fc4584c64a0000000000
})

const buf = Buffer.alloc(10)

randomFillSync(buf, 5, 5)

console.log(buf.toString('hex')) // 0000000000bcc09d5877
