Thanks, the file made it clear: you have a mistake in your file.<br>

The reference URI in RetrievalMethod should point to the <br>

KeyValue, not the KeyInfo. It is not clear rom the spec but take<br>

a look at the XML DSig archive:<br>

<br>

The correct file in your case should look like this one:<br>

<br>

&nbsp;&nbsp;&nbsp; &lt;KeyInfo xmlns=<a class="moz-txt-link-rfc2396E" href="http://www.w3.org/2000/09/xmldsig#">"http://www.w3.org/2000/09/xmldsig#"</a>&gt; <br>

&nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&lt;KeyValue Id="foo"&gt; <br>

&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; ...<br>

&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;/DSAKeyValue&gt;<br>

&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &lt;/KeyValue&gt;<br>

Sorry about that, I'm using the xmlsec application.&nbsp; That's what I meant

 by "xmlsec tool". <br>

 <br>

I'll attach the actual xml.&nbsp; To verify, I run: <br>

&nbsp;&nbsp;&nbsp; xmlsec verify &lt;file&gt; <br>
