Check password and create user manually with FOSUserBundle - symfony

Question

I'm using FOSUserBundle in my application. I would like to do two things via HTTP services:
Check password. The service could look like this (the password wouldn't be encrypted):
public function checkPasswordValidity($userId, $password) {
$user = $this->getDoctrine()
->getRepository('MyCompany\UserBundle\Entity\User')
->find($userId);
if (specialFunction($user , $password))
echo 'Valid Password';
else
echo 'Invalid Password';
}
Create a new user via another HTTP service. The parameters would be the username and the password.

Answer 1

Check password:
$encoder_service = $this->get('security.encoder_factory');
$encoder = $encoder_service->getEncoder($user);
$encoded_pass = $encoder->encodePassword($password, $user->getSalt());
//then compare $user->getPassword() and $encoded_pass
Create a new user:
$userManager = $this->get('fos_user.user_manager');
$user = $userManager->createUser();
$user->setUsername($login);
$user->setPlainPassword($pass);
...
$userManager->updateUser($user);

Answer 2

For me works:
$encoder_service = $this->get('security.encoder_factory');
$encoder = $encoder_service->getEncoder($user);
if ($encoder->isPasswordValid($user->getPassword(), $password, $user->getSalt()) {}
I did not test second question, but I think it is answered already.

Answer 3

Manually add new user :
Login to phpmyadmin , access fos_user_user table , click insert > fill fields , username , email,roles etc.
Generate salt and password using this php script:
<?php
$salt = base_convert(sha1(uniqid(mt_rand(), true)), 16, 36);
echo "Salt used: " . $salt ."<br/>";
echo "<br/>";
$password = 'adminpasswordhere';
$salted = $password.'{'.$salt.'}';
$digest = hash('sha512', $salted, true);
for ($i=1; $i<5000; $i++) {
$digest = hash('sha512', $digest.$salted, true);
}
$encodedPassword = base64_encode($digest);
echo "Password used: " . $password ."<br/>";
echo "<br/>";
echo "Encrypted Password: " . $encodedPassword ."<br/>";
?>
Enjoy !
