How admin password stored in database?

Question

I want to create an API point where the admin user can update their password, but I don't know what encrypt method used to encrypt the admin password and save it in the database, roughly what I want is like this:

$data = array(
          'user_id' => '1',
          'password' => 'magento2',
          'firstname' => 'Jane'
        );

$user = Mage::getModel('admin/user')->load($id);

if(isset($data['password')) $data['password'] = $this->encryptPassword($data['password']);
$user->addData($data);
$user->save();

Answer 1

In Magento 1.x, the admin password is saved as CONCAT(MD5('qXpassword'), ':qX'), where 'qX' is salt value for encryption and it can be any other string.

If you don't use salt concatenation, i.e. use a blank salt value, then you can simply use:

MD5('password')

to save the password of the admin user.

I hope I was clear enough to explain.

Please let me know if you have any confusion.

Unless it's changed recently it's MD5 See this post (found with a quick google search) What encryption model does Magento1 use?
