Simply set up authentication normally, using <code>AuthType Digest</code> and <code class="directive"><a href="#authdigestfile">AuthDigestFile</a></code> instead of the normal <code>AuthType Basic</code> and <code class="directive"><a href="../mod/mod_auth.html#authuserfile">AuthUserFile</a></code>; also, replace any <code class="directive"><a href="../mod/mod_auth.html#authgroupfile">AuthGroupFile</a></code> with <code class="directive"><a href="#authdigestgroupfile">AuthDigestGroupFile</a></code>. Then add a <code class="directive"><a href="#authdigestdomain">AuthDigestDomain</a></code> directive containing at least the root URI(s) for this protection space.</p> <p>Appropriate user (text) files can be created using the <code class="program"><a href="../programs/htdigest.html">htdigest</a></code> tool.</p> <div class="example"><h3>Example:</h3><p><code> <Location /private/><br /> <span class="indent"> AuthType Digest<br /> AuthName "private area"<br /> AuthDigestDomain /private/ http://mirror.my.dom/private2/<br /> AuthDigestFile /web/auth/.digest_pw<br /> Require valid-user<br /> </span> </Location> </code></p></div> <div class="note"><h3>Note</h3> <p>Digest authentication provides a more secure password system than Basic authentication, but only works with supporting browsers. As of November 2002, the major browsers that support digest authentication are <a href="http://www.opera.com/">Opera</a>, <a href="http://www.microsoft.com/windows/ie/">MS Internet Explorer</a> (fails when used with a query string - see "<a href="#msie">Working with MS Internet Explorer</a>" below for a workaround), <a href="http://www.w3.org/Amaya/">Amaya</a>, <a href="http://www.mozilla.org">Mozilla</a> and <a href="http://channels.netscape.com/ns/browsers/download.jsp">Netscape</a> since version 7. Since digest authentication is not as widely implemented as basic authentication, you should use it only in controlled environments.</p> </div></div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="section"><h2><a name="msie" id="msie">Working with MS Internet Explorer</a></h2> <p>The Digest authentication implementation in previous Internet Explorer for Windows versions (5 and 6) had issues, namely that <code>GET</code> requests with a query string were not RFC compliant. There are a few ways to work around this issue.</p> <p> The first way is to use <code>POST</code> requests instead of <code>GET</code> requests to pass data to your program. This method is the simplest approach if your application can work with this limitation. </p> <p>Since version 2.0.51 Apache also provides a workaround in the <code>AuthDigestEnableQueryStringHack</code> environment variable. If <code>AuthDigestEnableQueryStringHack</code> is set for the request, Apache will take steps to work around the MSIE bug and remove the query string from the digest comparison. Using this method would look similar to the following.</p> <div class="example"><h3>Using Digest Authentication with MSIE:</h3><p><code> BrowserMatch "MSIE" AuthDigestEnableQueryStringHack=On </code></p></div> <p>This workaround is not necessary for MSIE 7, though enabling it does not cause any compatibility issues or significant overhead.</p> <p>See the <code class="directive"><a href="../mod/mod_setenvif.html#browsermatch">BrowserMatch</a></code> directive for more details on conditionally setting environment variables</p></div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="directive-section"><h2><a name="AuthDigestAlgorithm" id="AuthDigestAlgorithm">AuthDigestAlgorithm</a> <a name="authdigestalgorithm" id="authdigestalgorithm">Directive</a></h2><table class="directive"><tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Selects the algorithm used to calculate the challenge andresponse hases in digest authentication</td></tr><tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>AuthDigestAlgorithm MD5|MD5-sess</code></td></tr><tr><th><a href="directive-dict.html#Default">Default:</a></th><td><code>AuthDigestAlgorithm MD5</code></td></tr><tr><th><a href="directive-dict.html#Context">Context:</a></th><td>directory, .htaccess</td></tr><tr><th><a href="directive-dict.html#Override">Override:</a></th><td>AuthConfig</td></tr><tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Experimental</td></tr><tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_auth_digest</td></tr></table> <p>The <code class="directive">AuthDigestAlgorithm</code> directive selects the algorithm used to calculate the challenge and response hashes.</p> <div class="note"> <code>MD5-sess</code> is not correctly implemented yet. </div> </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="directive-section"><h2><a name="AuthDigestDomain" id="AuthDigestDomain">AuthDigestDomain</a> <a name="authdigestdomain" id="authdigestdomain">Directive</a></h2><table class="directive"><tr><th><a href="directive-dict.html#Description">Description:</a></th><td>URIs that are in the same protection space for digestauthentication</td></tr><tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>AuthDigestDomain <var>URI</var> [<var>URI</var>] ...</code></td></tr><tr><th><a href="directive-dict.html#Context">Context:</a></th><td>directory, .htaccess</td></tr><tr><th><a href="directive-dict.html#Override">Override:</a></th><td>AuthConfig</td></tr><tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Experimental</td></tr><tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_auth_digest</td></tr></table> <p>The <code class="directive">AuthDigestDomain</code> directive allows you to specify one or more URIs which are in the same protection space (<em>i.e.</em> use the same realm and username/password info). The specified URIs are prefixes, <em>i.e.</em> the client will assume that all URIs "below" these are also protected by the same username/password. The URIs may be either absolute URIs (<em>i.e.</em> including a scheme, host, port, etc) or relative URIs.</p> <p>This directive <em>should</em> always be specified and contain at least the (set of) root URI(s) for this space. Omitting to do so will cause the client to send the Authorization header for <em>every request</em> sent to this server. Apart from increasing the size of the request, it may also have a detrimental effect on performance if <code class="directive"><a href="#authdigestnccheck">AuthDigestNcCheck</a></code> is on.</p> <p>The URIs specified can also point to different servers, in which case clients (which understand this) will then share username/password info across multiple servers without⌨️ 快捷键说明
