Function for node.js that will encrypt password exactly like Symfony2 PHP framework. So all passwords from Symfony2 will work in your node.js application
'use strict';
var crypto = require('crypto');
var _ = require('lodash');
/**
* Will encrypt password in Symfony2 way using a given salt.
*
* @param {string} password
* @param {string} salt
* @returns {string}
*/
function encryptPassword(password, salt){
var salted = `${password}{${salt}}`;
if (!salt){
salted = password;
}
var digest = crypto.createHash(this.algorithm).update(salted).digest('binary');
for (var i = 1; i < this.iterations; i++){
digest = crypto.createHash(this.algorithm).update( Buffer.concat([Buffer.from(digest, 'binary'), Buffer.from(salted, 'utf8')]) ).digest('binary');
}
return (Buffer.from(digest, 'binary')).toString('base64');
};

This doesn't currently work with Node 10.13.0. The concatenation of digest and salted causes issue and doesn't match Symfony. I got around this via the Buffer::concat method. See below;

        var salted = `${password}{${salt}}`;
        if (!salt){
            salted = password;
        }
        var digest = crypto.createHash(this.algorithm).update(salted).digest('binary'); 
        for (var i = 1; i < this.iterations; i++){
            digest = crypto.createHash(this.algorithm).update( Buffer.concat([Buffer.from(digest, 'binary'), Buffer.from(salted, 'utf8')]) ).digest('binary');
        }
        return (Buffer.from(digest, 'binary')).toString('base64');

Thanks for your code also!
