Examine the Contents of a .p7m by Converting to XML

Examines the contents of a .p7m signature by converting it to XML. C++

#include <CkAsn.h>
#include <CkXml.h>

void ChilkatSample(void)
    {
    bool success = false;

    //  This example requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    CkAsn asn;

    success = asn.LoadBinaryFile("qa_data/p7m/a.p7m");
    if (success != true) {
        std::cout << asn.lastErrorText() << "\r\n";
        return;
    }

    //  Convert to XML.
    const char *strXml = asn.asnToXml();

    //  The XML returned by AsnToXml will be compact.
    //  To get the XML indented in human-readable form, load
    //  into the Chilkat XML object and emit..
    CkXml xml;
    xml.LoadXml(strXml);

    std::cout << xml.getXml() << "\r\n";
    xml.SaveXml("qa_output/a.xml");
