New crypto capabilities in Node.js - UUID's and Primes

Much has been happening in the Node.js crypto subsystem lately. I introduced the Web Cryptography API implementation, and added the new support for the HKDF key derivation scheme previously. Here I discuss two powerful new capabilities for generating random UUIDs and random prime numbers. Read more: https://www.nearform.com/blog/new-crypto-capabilities-in-node-js/

randomuuid.js

import { randomUUID } from 'crypto'
console.log(randomUUID())

generateprime.js

const prime = crypto.generatePrimeSync(32)
console.log(prime)
 
// Or asynchronous ...
 
crypto.generatePrime(
  32,
  { safe: true, add: 2n, rem: 1n, bigint: true },
  (err, prime) => {
    console.log(prime)
  },
)
