Question

Say I have this set up as my encryption key and I already have the encrypt library on autoload:

$config['encryption_key'] = 'bjA{<ATCs1w5?,8N(bJvgO3CW_<]t?@o';

How do I use it in an encrypt function?

function s()
{
    $something = $this->encrypt->encode('eoaighaeg',$key);
    echo $this->encrypt->decode($something, $key); 
}

^ Non working example to give you an idea.

According to this documentation,
http://codeigniter.com/nightly_user_guide/libraries/encryption.html

If you didn’t supply any key parameter for $this->encrypt->encode() function, it automatically use config encryption key.

$this->encrypt->encode($msg);
