Member Variables

public string $algorithm
This should be MD5, since we only allow this one.

You should safely ignore this property.
public string $clientNonce
Request nonce generated by client (cnonce header field).
public mixed $nonce
The nounce used to hash the password.
public string $nonceCount
Serial number of the request (nc header field).
public string $opaque
Opaque value.

Generated by the server and re-submitted by the client as is, to verify correct communication.
public string $qualityOfProtection
The qop field of the request.
public string $realm
The authentication realm used.
public string $requestMethod
The method of the current request.
public string $response
The response hash.

This is the authentication value itself. It is a MD5 hashed version of the following string:
 1.  <?php
 2.  $ha1      := md5( "$username:$realm:$password" );
 3.  $ha2      := md5( "$method:$uri" );
 4.  $response := md5( "$ha1:$nonce:$nonceCount:$clientNonce:$qop:$ha2" );
 5.  ?>
public string $uri
The request URI.

Attention! This URI is not translated into a local path by the transport layer, since this would affect the hashing of $repsonse.
