I am trying to generate a token using JCryptCipherCrypto and I wanted to generate a string which will contain a-z, A-Z, 0-9 and length must be of 16 characters.

I have done this:

$crypto = new JCryptCipherCrypto;
$key = $crypto->generateKey();

Its method is not working or maybe I am doing something wrong :(

Can anyone tell me a better way to generate a token string or explain to me what I am missing?

  • Your server is probably missing mcrypt extension. Install / allow it and everything should work. Check here for more information. – Rene Korss Jun 20 '16 at 7:11
  • I have mycrypt extension enabled but still it is giving me result like this - VVz�E�$%����]6 – Joomler Jun 20 '16 at 10:29

This result is exactly what you want. Now you have a key to encrypt data. And later you can decrypt it with the same key.

// Test string
$str = 'Lorem ipsum...';

// Get key
$crypto = new JCryptCipherCrypto;
$key = $crypto->generateKey();

// Crypt it. Nobody can read it without key
$crypted = $crypto->encrypt($str, $key);

// Decrypt crypted string
$decrypted = $crypto->decrypt($crypted, $key);
echo $decrypted;

OUTPUT

Lorem ipsum...

For generating tokens I have used this method

function generateToken($length)
{
    jimport('joomla.user.helper');
    $token = JUserHelper::genRandomPassword($length);

    return $token;
}

Main advantage of this method is that I can generate random string up to 32 char.
