First, thanks to Matthew and sikkle for the great article!

I'd like to know if it's possible to use salts with the CodeIgniter Validation helper. I know you can automatically MD5/SHA passwords using the validation rules, but can you also salt it?

ExampleMD5, no salt)
$this->form_validation->set_rules('password', 'Password', 'trim|required|matches[password2]|md5');

Thanks!
