<p>thanks :)</p>
<p>But can you explain how i got the <span>concrete data like QCStatement? Because there is no defined structure in OpenSSL like for example CRLDistributionPoints. So which structure and functions i have to use, to get the matching data?</p>
<pre style="font-size: 16px; word-wrap: break-word; white-space: pre-wrap;">QCStatement ::= SEQUENCE {<br></pre>
</span>
<p></p>
<p><span></p>
<pre style="word-wrap: break-word; white-space: pre-wrap;"> statementId QC-STATEMENT.&Id({SupportedStatements}),
statementInfo QC-STATEMENT.&Type
({SupportedStatements}{@statementId}) OPTIONAL }</pre>
thanks again!</span>

To my knowledge, there is direct support for the qcStatements, you must parse it yourself.<br>
I asked for some help on the list more or less a month ago, I was trying to develop the required structures but apparently I got lost in the OpenSSL macro jungle, finally I had to quit working on it.<br>
What you can do is search for specific statements of interest to you (there are quite a bit) by parsing the attribute.<br>
Get the attribute NID of the object in the extension and see if it matches the NID of qcStatements:<br>
<br>
oneObj = X509_EXTENSION_get_object(oneExt);<br>
objnid = OBJ_obj2nid(theObj);<br>
if (objnid == NID_qcStatements)<br>
{ printf("DEBUG:ext:GOTCHA!:this is qcStatements!\n"); }<br>
<br>
you then extract the data from the object and parse it.<br>
For the moment I have this ugly quick way of doing it, for instance for a simple one:<br>
<br>
#define UC_id_etsi_qcs_QcCompliance "0.4.0.1862.1.1"<br>
<br>
if (strstr(extdump, UC_id_etsi_qcs_QcCompliance) == NULL)<br>
{ printf("INFO:QcCompliance:no:\n"); }<br>
else<br>
{ printf("INFO:QcCompliance:yes:\n"); }<br>
<br>
<br>
