Digest authentication is a method of HTTP authentication that improves upon Basic authentication by providing a way to authenticate without having to transmit the password in clear text across the network.
This adapter allows authentication against text files containing lines having the basic elements of Digest authentication:
username, such as "joe.user";
realm, such as "Administrative Area";
- an MD5 hash of the username, realm, and password, separated by colons.
The above elements are separated by colons, as in the following example (in which the password is "somePassword"):
The digest authentication adapter,
requires several input parameters:
filename: Filename against which authentication queries are performed.
realm: Digest authentication realm.
username: Digest authentication user.
password: Password for the user of the realm.
These parameters must be set prior to calling
The digest authentication adapter returns a
populated with the identity as an array containing the keys
username. The respective array values associated with these keys correspond
to the values set before
authenticate() is called.
use Zend\Authentication\Adapter\Digest as AuthAdapter; $adapter = new AuthAdapter( $filename, $realm, $username, $password ); $result = $adapter->authenticate(); $identity = $result->getIdentity(); print_r($identity); /* Array ( [realm] => Some Realm [username] => someUser ) */
