What are pbkdf2's main functionalities?

Deriving a key from a password

This code sample demonstrates how to use the pbkdf2 package to derive a cryptographic key from a password. It uses a random salt, a specified number of iterations, key length, and digest algorithm.

const crypto = require('crypto');
const pbkdf2 = require('pbkdf2');

const password = 'secret';
const salt = crypto.randomBytes(16).toString('hex');
const iterations = 100000;
const keylen = 64;
const digest = 'sha512';

pbkdf2.pbkdf2(password, salt, iterations, keylen, digest, (err, derivedKey) => {
  if (err) throw err;
  console.log(derivedKey.toString('hex')); // '3745e48...aa39b34'
});
