Digest Authentication adapter for AuthComponent.
Provides Digest HTTP authentication support for AuthComponent.
In your controller's components array, add auth + the required config
public $components = [
'Auth' => [
'authenticate' => ['Digest']
]
]; You should also set AuthComponent::$sessionKey = false; in your AppController's beforeFilter() to prevent CakePHP from sending a session cookie to the client.
Since HTTP Digest Authentication is stateless you don't need a login() action in your controller. The user credentials will be checked on each request. If valid credentials are not provided, required authentication headers will be sent by this authentication provider which triggers the login dialog in the browser/client.
You may also want to use $this->Auth->unauthorizedRedirect = false;. This causes AuthComponent to throw a ForbiddenException exception instead of redirecting to another page.
DigestAuthenticate requires a special password hash that conforms to RFC2617. You can generate this password using DigestAuthenticate::password()
$digestPass = DigestAuthenticate::password($username, $password, env('SERVER_NAME')); If you wish to use digest authentication alongside other authentication methods, it's recommended that you store the digest authentication separately. For example User.digest_pass could be used for a digest password, while User.password would store the password hash for use with other methods like Basic or Form.
Cake\Auth\BasicAuthenticate
Cake\Auth\DigestAuthenticate __construct( Cake\Controller\ComponentRegistry $registry , array $config [] )
Constructor
Besides the keys specified in BaseAuthenticate::$_defaultConfig, DigestAuthenticate uses the following extra keys:
realm The realm authentication is for, Defaults to the servername.nonce A nonce used for authentication. Defaults to uniqid().qop Defaults to 'auth', no other values are supported at this time.opaque A string that must be returned unchanged by clients. Defaults to md5($config['realm'])
Cake\Controller\ComponentRegistry $registry The Component registry used on this request.
$config optional [] Cake\Auth\BaseAuthenticate::__construct() _getDigest( Cake\Network\Request $request )
Gets the digest headers from the request/environment.
Cake\Network\Request $request generateResponseHash( array $digest , string $password , string $method )
Generate the response hash for a given digest array.
$digest $password $method getUser( Cake\Network\Request $request )
Get a user based on information in the request. Used by cookie-less auth for stateless clients.
Cake\Network\Request $request Cake\Auth\BasicAuthenticate::getUser() loginHeaders( Cake\Network\Request $request )
Generate the login headers
Cake\Network\Request $request Cake\Auth\BasicAuthenticate::loginHeaders() parseAuthData( string $digest )
Parse the digest authentication headers and split them up.
$digest password( string $username , string $password , string $realm )
Creates an auth digest password hash to store
$username $password $realm authenticate( Cake\Network\Request $request , Cake\Network\Response $response )
Authenticate a user using HTTP auth. Will use the configured User model and attempt a login using HTTP auth.
Cake\Network\Request $request Cake\Network\Response $response unauthenticated( Cake\Network\Request $request , Cake\Network\Response $response )
Handles an unauthenticated access attempt by sending appropriate login headers
Cake\Network\Request $request Cake\Network\Response $response Cake\Network\Exception\UnauthorizedExceptionCake\Auth\BaseAuthenticate::unauthenticated() _findUser( string $username , string|null $password null )
Find a user record using the username and password provided.
Input passwords will be hashed even when a user doesn't exist. This helps mitigate timing attacks that are attempting to find valid usernames.
$username $password optional null The password, if not provided password checking is skipped and result of find is returned.
_query( string $username )
Get query object for fetching user from database.
$username Cake\ORM\QueryimplementedEvents( )
Returns a list of all events that this authenticate class will listen to.
An authenticate class can listen to following events fired by AuthComponent:
Auth.afterIdentify - Fired after a user has been identified using one of configured authenticate class. The callback function should have signature like afterIdentify(Event $event, array $user) when $user is the identified user record.
Auth.logout - Fired when AuthComponent::logout() is called. The callback function should have signature like logout(Event $event, array $user) where $user is the user about to be logged out.
[].Cake\Event\EventListenerInterface::implementedEvents() needsPasswordRehash( )
Returns whether or not the password stored in the repository for the logged in user requires to be rehashed with another algorithm
passwordHasher( )
Return password hasher object
Cake\Auth\AbstractPasswordHasherIf password hasher class not found or it does not extend AbstractPasswordHasher
_configDelete( string $key )
Delete a single config key
$key Cake\Core\Exception\Exception_configRead( string|null $key )
Read a config variable
$key _configWrite( string|array $key , mixed $value , boolean|string $merge false )
Write a config variable
$key $value $merge optional false True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.
Cake\Core\Exception\Exceptionconfig( string|array|null $key null , mixed|null $value null , boolean $merge true )
Reading the whole config:
$this->config();
Reading a specific value:
$this->config('key'); Reading a nested value:
$this->config('some.nested.key'); Setting a specific value:
$this->config('key', $value); Setting a nested value:
$this->config('some.nested.key', $value); Updating multiple config settings at the same time:
$this->config(['one' => 'value', 'another' => 'value']);
$key optional null $value optional null $merge optional true Cake\Core\Exception\ExceptionconfigShallow( string|array $key , mixed|null $value null )
Merge provided config with existing config. Unlike config() which does a recursive merge for nested keys, this method does a simple merge.
Setting a specific value:
$this->config('key', $value); Setting a nested value:
$this->config('some.nested.key', $value); Updating multiple config settings at the same time:
$this->config(['one' => 'value', 'another' => 'value']);
$key $value optional null
