check symfony, fos-user encrypted password with nodejs - php

Question

I need to validate a password in a Symfony 3.3 / FriendsOfSymfony UserBundle 1.3 application from an AWS Lambda function.
The relevant password hashing code in Symfony is here https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Security/Core/Encoder/MessageDigestPasswordEncoder.php#L52
However the code doesn't produce the same hashes even at the first line.
In Symfony with password=test, salt=asLZCFQJ5flTtOWdphjKtpngthjK6h2FtMRSIZZ2bus
$salted = $this->mergePasswordAndSalt($raw, $salt);
$digest = hash($this->algorithm, $salted, true);
//base64_encode($digest) == '2QhirHmPwt0O5MrtTdfWsWKCCeOQO/y02Di04/aUIJxWhdNDQSGCaUuL1ONLUasdsD88CBSIzGwsePqGTCcQmA=='
// "stretch" hash
for ($i = 1; $i < $this->iterations; ++$i) {
$digest = hash($this->algorithm, $digest.$salted, true);
}
With the same details in nodejs I get:
var pass='test';
var salt='asLZCFQJ5flTtOWdphjKtpngthjK6h2FtMRSIZZ2bus';
var salted = pass + '{' + salt + '}';
var digest = sha512.update(salted).digest('binary');
//new Buffer(digest).toString('base64') == 'w5kIYsKsecKPw4LDnQ7DpMOKw61Nw5fDlsKxYsKCCcOjwpA7w7zCtMOYOMK0w6PDtsKUIMKcVsKFw5NDQSHCgmlLwovDlMOjS1HCqx3CsD88CBTCiMOMbCx4w7rChkwnEMKY'
for (var i = 1; i < 5000; ++i) {
digest = require('crypto').createHash('sha512').update(digest + salted).digest('binary');
process.stdout.write(new Buffer(digest).toString('base64')+"\n");
}
or is this a character encoding problem? The first 3 characters of the binary hash look very similar in the debuggers.

Answer 1

Finally i figured it out, hope it can help someone in the future.The issue comes from characters contact.
./middleware/passwordEncode.js:
const cryptoLib = require('crypto');
const encryptPassword = (password:any, salt:any) => {
let salted = password + '{' + salt + '}';
if (!salt){
salted = password;
}
let digest = cryptoLib.createHash('sha512').update(salted).digest('binary');
for (let i = 1; i < 5000; i++){
digest = cryptoLib.createHash('sha512').update( Buffer.concat([Buffer.from(digest, 'binary'), Buffer.from(salted, 'utf8')]) ).digest('binary');
}
return ( Buffer.from(digest, 'binary')).toString('base64');
}
module.exports.encryptPassword = encryptPassword;
./middleware/passwordDecode.js:
const passwordEncode = require('../middleware/passwordEncode')
const verifyPassword = (password:any, salt:any, encoded:any) => {
return encoded === passwordEncode.encryptPassword(password,salt);
}
module.exports.verifyPassword = verifyPassword

I have resolved this by switching the encryption method to bcrypt. This answer describes how to check the resulting password:https://stackoverflow.com/a/26643637/123594
