How to decrypt Laravel's sessionID in NodeJS

// requirements
var PHPUnserialize = require('php-unserialize'); // npm install php-unserialize
var MCrypt = require('mcrypt').MCrypt; // npm install mcrypt


// helper function

function ord( string ) {    // Return ASCII value of character
    // 
    // +   original by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)

    return string.charCodeAt(0);
}


function getSessionIdFromLaravelCookie() {

    var cookie = JSON.parse(new Buffer(req.cookies.laravel_session, 'base64'));
    var iv = new Buffer(cookie.iv, 'base64');
    var value = new Buffer(cookie.value, 'base64');
    var key = "_Encryption Key_";

    var rijCbc = new MCrypt('rijndael-256', 'cbc');
    rijCbc.open(key, iv); // it's very important to pass iv argument!

    var decrypted = rijCbc.decrypt(value).toString();


    var len = decrypted.length - 1;
    var pad = ord(decrypted.charAt(len));

    var sessionId = PHPUnserialize.unserialize(decrypted.substr(0, decrypted.length - pad));

    return sessionId;

}
