javascript - PHP And Node.JS - Crypto PBKDF2 -

i trying node.js crypto pbkdf2 match same value php crypto pbkdf2. reason, not same.

in javascript

const crypto = require('crypto'); crypto.pbkdf2('secret', 'salt', 100000, 20, 'sha512', (err, key) => {    console.log(key.tostring());  }); 

output: 7e������]�9��j]�i

in php

$password = "secret"; $iterations = 100000; $salt = "salt";  $hash = hash_pbkdf2("sha512", $password, $salt, $iterations, 20); echo $hash; 

output: 3745e482c6e0ade35da1

why js output not matching php?

you can use option raw_output of hash_pbkdf2 method in php , compare base64

in php

<?php $password = "secret"; $iterations = 100000; $salt = "salt";  $hash = hash_pbkdf2("sha512", $password, $salt, $iterations, 20, true); echo base64_encode($hash); ?> 

live example

in nodejs

const crypto = require('crypto'); crypto.pbkdf2('secret', 'salt', 100000, 20, 'sha512', (err, key) => { console.log(new buffer(key).tostring('base64')); });
