  3. after more help from jacques1 i've been tring to use nodejs's crypto...i want to be able to encryt data via js and decrypt via php and visa versa. in my aes.js i have created function so i can encrypt and decrypt data although i get an error on both and i'm completely stuck! to be honest all this encrypting and decrypting is quite confusing to say the least and could really do with some more help...the iv length is set at 32 which is obviously too shore or too long...where am i going wrong here please? here is all my code that i am using for this test.js var aes = require('./aes'), master_key = "5e2a0626516f3108e55e25e4bb6a62835c2f5d2b2b8d194c9acca63ef8beff6bfb947233bd83cfda9021e5a80bc183bcd835180c9955b733fd1a6d9d"; var decrypt = aes.decrypt("yUB2jQe88yWT2yUNHstMCw==", "2a3dc736bc316e9a20566b9a108eb23a", master_key); console.log('decrypt', decrypt); var encrypted = aes.encrypt('destramic', master_key); console.log('encrypt', encrypted); // array from aes.php encrypted and decrypted. //Array //( // [0] => Array // ( // [name] => yUB2jQe88yWT2yUNHstMCw== // [name_init_vector] => 2a3dc736bc316e9a20566b9a108eb23a // [age] => PjDxZq2x5IrhsLcqaJd5JQ== // [age_init_vector] => 01b53388ddcd8352db17e30f44e9b9e8 // ) // // [1] => Array // ( // [name] => LRxu9zAdlkSgS+wmyi4PrQ== // [name_init_vector] => 1c3d3bf95168ab025ca5c63ec3926313 // [age] => ys6yPHqjtutq/PJ5G3r0FQ== // [age_init_vector] => f19b6975eece8d8995e86b0ee6a33569 // ) // //) //Array //( // [0] => Array // ( // [name] => destramic // [age] => 28 // ) // // [1] => Array // ( // [name] => alan // [age] => 99 // ) // //) aes.js - where my problem ara... var crypto = require('crypto'), encryption_algorithem = 'AES-128-CBC'; module.exports = { encrypt: function (text, master_key){ try { var init_vector = new Buffer(crypto.randomBytes(32)); ciphertext = crypto.createCipheriv(encryption_algorithem, master_key, init_vector); init_vector = init_vector.update('hex'); return {'ciphertext' : ciphertext, 'init_vector' : init_vector }; }catch(error){ console.log(error); return null; } }, decrypt: function (ciphertext, init_vector, master_key){ try { var decipher = crypto.createDecipheriv(encryption_algorithem, master_key, init_vector), decrypted = decipher.update(ciphertext, 'bin'); return decrypted; }catch(error){ console.log(error); return null; } } }; aes.php <?php const ENCRYPTION_ALGORITHM = 'AES-128-CBC'; class AES { private $_master_key; public function __construct() { $this->_master_key = "5e2a0626516f3108e55e25e4bb6a62835c2f5d2b2b8d194c9acca63ef8beff6bfb947233bd83cfda9021e5a80bc183bcd835180c9955b733fd1a6d9d"; } public function generate_master_key($length = 64) { if (!is_numeric($length)) { return null; } $max_attempts = 10; $attempts = 0; do { $bytes = openssl_random_pseudo_bytes($length, $cryptographically_strong); $attempts++; } while (!$cryptographically_strong && $attempts < $max_attempts); if (!$cryptographically_strong) { return false; } $hex = bin2hex($bytes); return $hex; } public function encrypt($value, $master_key) { $init_vector = openssl_random_pseudo_bytes(openssl_cipher_iv_length(ENCRYPTION_ALGORITHM)); $ciphertext = openssl_encrypt($value, ENCRYPTION_ALGORITHM, $master_key, false, $init_vector); return array( 'init_vector' => bin2hex($init_vector), 'ciphertext' => $ciphertext ); } public function decrypt($ciphertext, $init_vector, $master_key) { $plaintext = openssl_decrypt($ciphertext, ENCRYPTION_ALGORITHM, $master_key, false, hex2bin($init_vector)); return $plaintext; } public function encrypt_array($array) { $encrypted_array = array(); $master_key = $this->_master_key; foreach ($array as $key => $data) { foreach ($data as $column => $value) { $encryption = $this->encrypt($value, $master_key); $init_vector_column = $column .

  4. Hello. I've gotten my self really confused with server end checks for users being logged in. I create a session in PHP by using a straight forward ajax request and check the database against the user & pass sent to the server. I then set a session like this: $_SESSION['uid'] = $row['uid']; But i want to check this session in NodeJS aswell so i don't have to keep validating the user when they send data on a socket. The script i have is like this: socket.on('sendMessage', function(data,callBack){ var userID = //assign $_SESSION['uid'], possible? if(!userID){ console.log('User not logged in!'); } else { var message = sanitize(data['message']).escape(); var query = connection.query('SELECT name FROM users WHERE uid = ?', [userID], function(err,results){ if(err){ console.log('Query Error: '+err); } else if(results.length == 1){ var username = results[0].name; console.log(username+' sent a message!'); } }); }); How do i use the session in this situation - i can't work out how to do it =/ Please help, really confused!
