+<!--%plaintext &lt;?INDEX {\tt ContentDigest} directive&gt; -->
+<strong>Syntax:</strong> ContentDigest <em>on|off</em><br>
+<strong>Default:</strong> <code>ContentDigest off</code><br>
+<strong>Context:</strong> any<br>
+<strong>Override:</strong> AuthConfig<br>
+<strong>Status:</strong> experimental<p>
+<strong>Compatibility:</strong> ContentDigest is only available in Apache 1.1 and later<p>
+
+This directive enables the generation of <code>Content-MD5</code> headers
+as defined in RFC1864 respectively RFC2068.<P>
+
+MD5 is an algorithm for computing a "message digest" (sometimes called
+"fingerprint") of arbitrary-length data, with a high degree of confidence
+that any alterations in the data will be reflected in alterations in the
+message digest.<P>
+
+The <code>Content-MD5</code> header provides an end-to-end message
+integrity check (MIC) of the entity-body. A proxy or client may check this
+header for detecting accidental modification of the entity-body
+in transit.
+Example header:
+<pre>   Content-MD5: AuLb7Dp1rqtRtxz2m9kRpA==</pre><P>
+
+Note that this can cause performance problems on your server
+since the message digest is computed on every request
+(the values are not cached).
