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 install random-poly-fill --save
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
crypto.randomFill(buffer[, offset][, size], callback)
