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.
__construct( Cake\Controller\ComponentRegistry $registry , array $config [] )
Constructor
Besides the keys specified in BaseAuthenticate::$_defaultConfig, DigestAuthenticate uses the following extra keys:
secret
The secret to use for nonce validation. Defaults to Security.salt.realm
The realm authentication is for, Defaults to the servername.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'])
nonceLifetime
The number of seconds that nonces are valid for. Defaults to 300.Cake\Controller\ComponentRegistry
$registry
The Component registry used on this request.
$config
optional [] Cake\Auth\BaseAuthenticate::__construct()
_getDigest( Cake\Http\ServerRequest $request )
Gets the digest headers from the request/environment.
Cake\Http\ServerRequest
$request
generateNonce( )
Generate a nonce value that is validated in future requests.
generateResponseHash( array $digest , string $password , string $method )
Generate the response hash for a given digest array.
$digest
$password
$method
getUser( Cake\Http\ServerRequest $request )
Get a user based on information in the request. Used by cookie-less auth for stateless clients.
Cake\Http\ServerRequest
$request
Cake\Auth\BasicAuthenticate::getUser()
loginHeaders( Cake\Http\ServerRequest $request )
Generate the login headers
Cake\Http\ServerRequest
$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
validNonce( string $nonce )
Check the nonce to ensure it is valid and not expired.
$nonce
authenticate( Cake\Http\ServerRequest $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\Http\ServerRequest
$request
$response
unauthenticated( Cake\Http\ServerRequest $request , Cake\Network\Response $response )
Handles an unauthenticated access attempt by sending appropriate login headers
Cake\Http\ServerRequest
$request
$response
Cake\Network\Exception\UnauthorizedException
Cake\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\Query
implementedEvents( )
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\AbstractPasswordHasher
If password hasher class not found or it does not extend AbstractPasswordHasher
_configDelete( string $key )
Deletes a single config key.
$key
Cake\Core\Exception\Exception
_configRead( string|null $key )
Reads a config key.
$key
_configWrite( string|array $key , mixed $value , boolean|string $merge false )
Writes a config key.
$key
$value
$merge
optional false True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.
Cake\Core\Exception\Exception
config( string|array|null $key null , mixed|null $value null , boolean $merge true )
Gets/Sets the config.
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\Exception
configShallow( 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']);

$value
optional null getConfig( string|null $key null )
Returns the config.
Reading the whole config:
