Constructor & Destructor Documentation

__construct ( array $config )

Constructor.

Parameters

array $config Configuration settings: 'accept_schemes' => 'basic'|'digest'|'basic digest' 'realm' => <string> 'digest_domains' => <string> Space-delimited list of URIs 'nonce_timeout' => <int> 'use_opaque' => <bool> Whether to send the opaque value in the header 'alogrithm' => <string> See $_supportedAlgos. Default: MD5 'proxy_auth' => <bool> Whether to do authentication as a Proxy

Exceptions

Zend_Auth_Adapter_Exception

Returns: void

Member Function Documentation

_basicAuth ( $header )

protected

Basic Authentication.

Parameters

string $header Client's Authorization header

Exceptions

Zend_Auth_Adapter_Exception

Returns: Zend_Auth_Result

See Also: Zend_Auth_Adapter_Exception; Zend_Auth_Adapter_Exception; Zend_Auth_Adapter_Exception

_basicHeader ( )

protected

Basic Header.

Generates a Proxy- or WWW-Authenticate header value in the Basic authentication scheme.

Returns: string Authenticate header value

_calcNonce ( )

protected

Calculate Nonce.

Returns: string The nonce value

_calcOpaque ( )

protected

Calculate Opaque.

The opaque string can be anything; the client must return it exactly as it was sent. It may be useful to store data in this string in some applications. Ideally, a new value for this would be generated each time a WWW-Authenticate header is sent (in order to reduce predictability), but we would have to be able to create the same exact value across at least two separate requests from the same client.

Returns: string The opaque value

_challengeClient ( )

protected

Challenge Client.

Sets a 401 or 407 Unauthorized response code, and creates the appropriate Authenticate header(s) to prompt for credentials.

Returns: Zend_Auth_Result Always returns a non-identity Auth result

_digestAuth ( $header )

protected

Digest Authentication.

Parameters

string $header Client's Authorization header

Exceptions

Zend_Auth_Adapter_Exception

Returns: Zend_Auth_Result Valid auth result only on successful auth

See Also: Zend_Auth_Adapter_Exception; Zend_Auth_Adapter_Exception; Zend_Auth_Adapter_Exception

_digestHeader ( )

protected

Digest Header.

Generates a Proxy- or WWW-Authenticate header value in the Digest authentication scheme.

Returns: string Authenticate header value

_parseDigestAuth ( $header )

protected

Parse Digest Authorization header.

Parameters

string $header Client's Authorization: HTTP header

Returns: array|false Data elements from header, or false if any part of the header is invalid

_secureStringCompare	(	$a,
		$b
	)

protected

Securely compare two strings for equality while avoided C level memcmp() optimisations capable of leaking timing information useful to an attacker attempting to iteratively guess the unknown string (e.g.

password) being compared against.

Parameters

string	$a
string	$b

Returns: bool

authenticate ( )

Authenticate.

Exceptions

Zend_Auth_Adapter_Exception

Returns: Zend_Auth_Result

See Also: Zend_Auth_Adapter_Exception; Zend_Auth_Adapter_Exception
