// When I look at the complicated XML above, there are specific things I look at to get a handle
// on the situation.
//
// 1) Does the signature already embed the public keys required for verification?
// Within each <ds:Signature>, look for the <ds:KeyInfo>. In this case, I can see that
// each signature contains the full X.509 certificate needed to verify (<ds:KeyInfo><ds:X509Data><ds:X509Certificate>).
// This means that Chilkat will automatically use the public keys contained within the base64 certificates
// already present in the signature.
//
// 2) Look at each <ds:Reference> within each <ds:Signature>. Do the URI attribute values begin with "#"?
// If so, then these are same-document references, and there's no need to explicitly fetch external data for reference verification.
// Chilkat can automatically validate each same-document Reference.
//
// So it turns out that this seemingly formidable XML document is easy to verify...
// Here we go...
i = 0;
while (i < CkXmlDSig_getNumSignatures(verifier)) {
// The Selector property is used to set our context to the Nth signature.
// For example, if VerifySignature is called when Selector = 0, then the 1st signature is verified.
// If VerifySignature is called when Selector = 1, then the 2nd signature is verified, and so on.
CkXmlDSig_putSelector(verifier,i);
verifyReferenceDigests = TRUE;
// The quick way to validate all references and the signature over the SignedInfo
// is to call VerifySignature with verifyReferenceDigests equal to TRUE.
verified = CkXmlDSig_VerifySignature(verifier,verifyReferenceDigests);
printf("Signature %d and all reference digests verified = %d\n",i + 1,verified);
// We can also get information about each signature.
// For example, we could get information about each Reference...
// The NumReferences property returns the number of references for the Signature indicated by the Selector property.
numReferences = CkXmlDSig_getNumReferences(verifier);
printf(" number of references: %d\n",numReferences);
j = 0;
while (j < numReferences) {
// Get information about the Jth reference in the Ith signature.
printf(" reference %d:\n",j);
// Is this a same-document or external reference?
printf(" is external: %d\n",CkXmlDSig_IsReferenceExternal(verifier,j));
// For external references, the URI could be used by an application to fetch the referenced data...
printf(" uri: %s\n",CkXmlDSig_referenceUri(verifier,j));
j = j + 1;
