<h2><a name="using" id="using">Using Digest Authentication</a></h2>
<p>Using MD5 Digest authentication is very simple. Simply set
up authentication normally, using <code>AuthType Digest</code> and
<code class="directive"><a href="#authdigestprovider">AuthDigestProvider</a></code>
instead of the normal <code>AuthType Basic</code> and
<code class="directive"><a href="../mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</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 />
<br />
AuthDigestProvider file<br />
AuthUserFile /web/auth/.digest_pw<br />
Require valid-user<br />
</span>
</Location>
</code></p></div>
<div class="note"><h3>Note</h3>
<p>Digest authentication is more secure than Basic authentication,
but only works with supporting browsers. As of this writing (December
2012) all major browsers support digest authentication.</p>

<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; 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
prompting the user each time. </p>

<p>The <code class="directive">AuthDigestNonceLifetime</code> directive
controls how long the server nonce is valid. When the client
contacts the server using an expired nonce the server will send
back a 401 with <code>stale=true</code>. If <var>seconds</var> is
greater than 0 then it specifies the amount of time for which the
nonce is valid; this should probably never be set to less than 10
seconds. If <var>seconds</var> is less than 0 then the nonce never
expires.

<p>The <code class="directive">AuthDigestQop</code> directive determines
the <dfn>quality-of-protection</dfn> to use. <code>auth</code> will
only do authentication (username/password); <code>auth-int</code> is
authentication plus integrity checking (an MD5 hash of the entity
is also computed and checked); <code>none</code> will cause the module
to use the old RFC-2069 digest algorithm (which does not include
integrity checking). Both <code>auth</code> and <code>auth-int</code> may
be specified, in which the case the browser will choose which of
these to use. <code>none</code> should only be used if the browser for
some reason does not like the challenge it receives otherwise.</p>

<p>The <code class="directive">AuthDigestShmemSize</code> directive defines
the amount of shared memory, that will be allocated at the server
startup for keeping track of clients. Note that the shared memory
segment cannot be set less than the space that is necessary for
tracking at least <em>one</em> client. This value is dependant on your
system. If you want to find out the exact value, you may simply
set <code class="directive">AuthDigestShmemSize</code> to the value of
<code>0</code> and read the error message after trying to start the
server.</p>
<p>The <var>size</var> is normally expressed in Bytes, but you
may let the number follow a <code>K</code> or an <code>M</code> to
express your value as KBytes or MBytes. For example, the following
directives are all equivalent:</p>
<div class="example"><p><code>
AuthDigestShmemSize 1048576<br />
AuthDigestShmemSize 1024K<br />
AuthDigestShmemSize 1M
