Details

Configuration for built-in password types.

Maps the password type to an array of options:

• class - The Password class to use.
• factory (introduced in 1.40) - A function that creates and returns a suitable Password object. This option is intended only for internal use; the function signature is unstable and subject to change in future versions.

All other options are class-dependent.

Example

The following example shows on how user-defined password encryptions can be added to the LocalSettings.php file:

$wgPasswordConfig['bcrypt-peppered'] = [
    'class' => 'EncryptedPassword',
    'underlying' => 'bcrypt',
    'secrets' => array(),
    'cipher' => MCRYPT_RIJNDAEL_256,
    'mode' => MCRYPT_MODE_CBC,
    'cost' => 5,
];
