thanks :) But can you explain how i got the 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?
QCStatement ::= SEQUENCE { statementId QC-STATEMENT.&Id({SupportedStatements}), statementInfo QC-STATEMENT.&Type ({SupportedStatements}{@statementId}) OPTIONAL } thanks again! ________________________________ Von: openssl-users <openssl-users-boun...@openssl.org> im Auftrag von lists <li...@rustichelli.net> Gesendet: Mittwoch, 26.

To my knowledge, there is direct support for the qcStatements, you must parse it yourself. 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. What you can do is search for specific statements of interest to you (there are quite a bit) by parsing the attribute. Get the attribute NID of the object in the extension and see if it matches the NID of qcStatements: oneObj = X509_EXTENSION_get_object(oneExt); objnid = OBJ_obj2nid(theObj); if (objnid == NID_qcStatements) { printf("DEBUG:ext:GOTCHA!:this is qcStatements!\n"); } you then extract the data from the object and parse it. For the moment I have this ugly quick way of doing it, for instance for a simple one: #define UC_id_etsi_qcs_QcCompliance "0.4.0.1862.1.1" if (strstr(extdump, UC_id_etsi_qcs_QcCompliance) == NULL) { printf("INFO:QcCompliance:no:\n"); } else { printf("INFO:QcCompliance:yes:\n"); } Thanks Matthias
