While suitable for most modern browsers, mod_digest is known to not work with Microsoft Internet Explorer. Please see <a href="mod_auth_digest.html">mod_auth_digest</a> for a module which implements the most recent version of the standard and does not suffer from the same limitations as mod_digest.</p> <h2>Directives</h2> <ul> <li><a href="#authdigestfile">AuthDigestFile</a></li> </ul> <h2>Using Digest Authentication</h2> <p>Using MD5 Digest authentication is very simple. Simply set up authentication normally. However, use "AuthType Digest" and "AuthDigestFile" instead of the normal "AuthType Basic" and "AuthUserFile".</p> <p>As to make sure that replay is not possible across sections of the site, or across sites (assuming a realm, userid and password are valid in that wider context) a secret nonce prefix can be configured with the core directive <a href="core.html#AuthDigestRealmSeed">AuthDigestRealmSeed</a>. </p> <p>If none if configured a sensible, but not particular secure, default is used. When used in load balancing situations the prefix should be shared across servers. </p> <p>The experimental <a href="mod_auth_digest.html">mod_auth_digest</a> module offers a number of additinal protections against replay. </p> <p>Everything else should remain the same.</p> <p>MD5 authentication provides a more secure password system, but only works with supporting browsers. As of this writing (December 2003) most major browsers, including <a href="http://www.microsoft.com/windows/ie/">MS Internet Explorer</a>, <a href="http://www.opera.com/">Opera</a>, <a href="http://www.netscape.com/">Netscape</a>, <a href="http://www.mozilla.org/">Mozilla</a>, and <a href="http://www.w3.org/Amaya/">Amaya</a>, support the Digest authentication scheme. However, of this list MS Internet Explorer is known to be incompatable with the older digest authentication format supported by this module. Therefore, we do not recommend using this module on a large Internet site. However, for personal and intra-net use, where browser users can be controlled, it is ideal.</p> <p>See also <a href="mod_auth_digest.html">mod_auth_digest</a>, which is an updated version of this module, in order to determine whether you want to use that module instead. In either case, if you are using one, you should not use the other, as they share some of the same configuration directives.</p> <hr /> <h2><a id="authdigestfile" name="authdigestfile">AuthDigestFile</a> directive</h2> <a href="directive-dict.html#Syntax" rel="Help"><strong>Syntax:</strong></a> AuthDigestFile <em>filename</em><br /> <a href="directive-dict.html#Context" rel="Help"><strong>Context:</strong></a> directory, .htaccess<br /> <a href="directive-dict.html#Override" rel="Help"><strong>Override:</strong></a> AuthConfig<br /> <a href="directive-dict.html#Status" rel="Help"><strong>Status:</strong></a> Base<br /> <a href="directive-dict.html#Module" rel="Help"><strong>Module:</strong></a> mod_digest <p>The AuthDigestFile directive sets the name of a textual file containing the list of users and encoded passwords for digest authentication. <em>Filename</em> is the absolute path to the user file.</p> <p>Example</p> <code>AuthDigestFile /usr/local/apache/passwords/passwords.digest</code> <p>The digest file uses a special format.
