Drupal 8 and Drupal 7 use SHA512 by default with a salt. They run the hash through PHP's hash function numerous times to increase the computation cost of generating a password's final hash (a security technique called stretching).,drupal 7 use SHA-512 + salt,I am trying to figure out what is the security that Drupal 6/7 uses by default to store passwords. Is it MD5, AES, SHA? I have been unable to find anything.,Connect and share knowledge within a single location that is structured and easy to search.

It can be checked inside www\includes\password.inc

function user_check_password($password, $account) {
   if (substr($account - > pass, 0, 2) == 'U$') {
      // This may be an updated password from user_update_7000(). Such hashes
      // have 'U' added as the first character and need an extra md5().
      $stored_hash = substr($account - > pass, 1);
      $password = md5($password);
   } else {
      $stored_hash = $account - > pass;
   }

   $type = substr($stored_hash, 0, 3);
   switch ($type) {

It uses sha512, and also uses a salt for security sake. the actual function used for the hashing is: https://api.drupal.org/api/drupal/includes!password.inc/function/_passwo...,Diversity, Equity, and Inclusion Resources,Sign up for Drupal news,SolutionsBy industry By feature Case studies For hosting

Create password-change.php file equivalent to site folder and add below code on it.

define('DRUPAL_ROOT', getcwd());

require_once DRUPAL_ROOT.
'/includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
require './includes/password.inc';
print user_hash_password('yourpassword');

PHPass was originally implemented in Drupal 7, with custom code in order to use sha-512 instead of md5 which was used by other implementations at the time, and then ported to Drupal 8.,The class that performs password hashing in 8 is PhpassHashedPassword, based on https://www.openwall.com/phpass/. On that site, it states:,I did find this issue regarding supporting Blowfish style passwords but not one for creating them. I assume if I wanted to import their current userbase with Blowfish style passwords, I would need this patch., Drupal Answers help chat

In Drupal, the password saved in the database is in encrypted format & obscured against brute force attacks.,1. First, we generated the password hash for the site using this script in Drupal’s root directory.,In Drupal 8, there are several ways to set an encrypted password.,Setting the password encryption in Drupal may not work as expected.

– Using the drush command:

drush8 user - password admin--password = "new_password"

I am trying to figure out what is the security that Drupal 6/7 uses by default to store passwords. Is it MD5, AES, SHA? I have been unable to find anything.,Drupal 8 and Drupal 7 use SHA512 by default with a salt. They run the hash through PHP's hash function numerous times to increase the computation cost of generating a password's final hash (a security technique called stretching).,Run mysql_secure_installation to change new password,I don't think you can specifically use expressions in the orderBy clause, but this should work for you.

I think you need to use datetime:normal as the key for your datetime column type.

'time_to_send' => array(
   'description' => 'When the message should arrive at the user',
   'type' => 'datetime:normal',
   'not null' => TRUE,
),

Other than that you can try specifying the column type as a MySQL DATETIME explicitly:

'time_to_send' => array(
   'description' => 'When the message should arrive at the user',
   'mysql_type' => 'DATETIME',
   'not null' => TRUE,
),

A secure framework or system does not store your passwords as is. It gets converted into hashes using one-way encryption functions(implying that there is no way to get your original password text from the hash) and is stored in the database.,For example, if your password is Sup3r5ecr3t123!, encrypting it using one of the many hash functions, we get:,The password_hash function returns the hashing algorithm, salt and other details as part the hashed output. This information can be used to verify the password using the password_verify function.,The password service in Drupal 8 does these set of functions, including hashing, checking/verification of passwords and salt generation. Let's quickly create 3 new users in Drupal 8, 2 of whom apparently have the same password.

We saw how general authentication works with Drupal 8 in the previous post. We shall see how the actual authentication happens when user logs in. It all begins with a humble login route in user.services.yml of the user module.

user.login:
   path: '/user/login'
defaults:
   _form: '\Drupal\user\Form\UserLoginForm'
_title: 'Log in'
requirements:
   _user_is_logged_in: 'FALSE'
options:
   _maintenance_access: TRUE
