Q:

password decode in controller

I use it to encode my password:
 $entity->setSalt(md5(time()));
 $encoder = new MessageDigestPasswordEncoder('sha1');
 $password = $encoder->encodePassword($editForm->get('password')->getData(), $entity->getSalt());
 $entity->setPassword($password);

But how could relizar step opposite? that is, how could I get the unencrypted password? if i use this
$entity->getPassword()

shows me this:
xOGjEeMdi4nwanOustbbJlDkug8=

Thank you very much for the reply. I am trying to create a form where users enter the old password and verify that it is true. in the form I have this:
            ->add('antigua', 'password', array('property_path' => false))
        ->add('password', 'repeated', array('first_name' => 'Nueva contraseña','second_name' => 'Repite contraseña','type' => 'password'));

and when I go to edit a user in the crud I have this:
in update action :
public function updateAction($id)
    {
        $em = $this->getDoctrine()->getEntityManager();

        $entity = $em->getRepository('miomioBundle:Empleado')->find($id);

        if (!$entity) {
            throw $this->createNotFoundException('Unable to find Empleado entity.');
        }

        $editForm   = $this->createForm(new EmpleadoType(), $entity);
        $deleteForm = $this->createDeleteForm($id);

        $request = $this->getRequest();
        **$entity->getPassword() is blank why?**
        $editForm->bindRequest($request);

        if ($editForm->isValid()){
            $em->persist($entity);
            $em->flush();
        }
            return $this->redirect($this->generateUrl('empleado_edit', array('id' => $id)));

        return array(
            'entity'      => $entity,
            'edit_form'   => $editForm->createView(),
            'delete_form' => $deleteForm->createView(),
        );
    }

the problem is I can not get the encoded password is blank. (in db is correct)
thanks

A:

You should encrypt the same way the old password was, the password entered by user. The result encrypted password should be the same.
$encoder = new MessageDigestPasswordEncoder('sha1');
$password = $encoder->encodePassword($editForm->get('antigua')->getData(), $entity->getSalt());

Now you can compare the old encrypted password with the new user entered one...
