how can i pass the encrypted data through redirect

Question

I have to access a function through redirect

i use this code

   function email_check()
{

    $email=$this->input->post('email');
    $data = array(
        'user_email' =>$email, 
        );
   $result = $this->UM->email_verify($data);
   echo $result;
   if($result)
   {

       $date   = date(Y-m-d);
       $string = $email."-".$date;
       $encrypted_string = md5($string);
       echo $encrypted_string;
       $res=$this->UM->insert_key($encrypted_string,$result);
       redirect(base_url()."user/pass_confirmation/".$encrypted_string.'/'.$email); 
     }
   }

But not working

Whats the problem here

     redirect(base_url()."user/pass_confirmation/".$encrypted_string.'/'.$email);

this link is correct but view page is not displayed in the function I have a doubt that is am passing an email through url

Without this display my view page

I think this a different question i am asking how to pass an encryped key and email through redirect
