user_pass_rehash

user_pass_rehash(UserInterface $account, $timestamp)

Creates a unique hash value for use in time-dependent per-user URLs.

This hash is normally used to build a unique and secure URL that is sent to the user by email for purposes such as resetting the user's password. In order to validate the URL, the same hash can be generated again, from the same information, and compared to the hash value from the URL. The hash contains the time stamp, the user's last login time, the numeric user ID, and the user's email address. For a usage example, see user_cancel_url() and \Drupal\user\Controller\UserController::confirmCancel().

Parameters

\Drupal\user\UserInterface $account: An object containing the user account.

int $timestamp: A UNIX timestamp, typically REQUEST_TIME.

Return value

string A string that is safe for use in URLs and SQL statements.

File

core/modules/user/user.module, line 645
Enables the user registration and login system.

Code

function user_pass_rehash(UserInterface $account, $timestamp) {
  $data = $timestamp;
  $data .= $account->getLastLoginTime();
  $data .= $account->id();
  $data .= $account->getEmail();
  return Crypt::hmacBase64($data, Settings::getHashSalt() . $account->getPassword());
}
