PHP Code Igniter Encryption doesn't return anything

when i load my controller i have this:

$this->load->library('encrypt');

$get = null;
parse_str($_SERVER['QUERY_STRING'],$get);
$email = $this->encrypt->decode($get["acc"]); // e.g.  www.lol.com/?acc=troll

And my controller is called like this:

$this->load->library('encrypt');
$this->load->helper("url");
$user = $this->input->post('email', true);

$encrypted_string = $this->encrypt->encode($user);
redirect('account/viewaccount?acc='.$encrypted_string);

The url looks like this:

http://localhost/CodeIgniter/index.php/account/viewaccount?acc=+fgSAs6X7ysW6XDjFVw//9RGVbY751zZv1LQ44yYBjhVuzI1BC1t9BbZCIUdX5lpYA==

But the problem is, when i encode i get a value, but then later on, when i decode this huge value (I can receive this value flawless, by testing) it returns nothing, just NULL.

Why is this happening?

Thank You

The output of the encryption is not URL safe. Replace this:

redirect('account/viewaccount?acc='.$encrypted_string);

With

redirect('account/viewaccount?acc='.urlencode($encrypted_string));

And then urldecode() it on the other end.

Encoded form is not url safe, try using some other encoding technique or urlencode the output of encode.
