I can verify a XML Signature with Apache Santuario XML security for Java. The code is like:
ByteArrayInputStream bais = new ByteArrayInputStream(readData("signature.xml"));
DocumentBuilderFactory f = DocumentBuilderFactory.newInstance();
f.setNamespaceAware(true);
Document doc = f.newDocumentBuilder().parse(bais);
bais.close();
NodeList nodes = doc.getElementsByTagNameNS(Constants.SignatureSpecNS, Constants._TAG_SIGNATURE);
Element sigElement = (Element) nodes.item(0);
XMLSignature signature = new XMLSignature(sigElement, "");
signature.addResourceResolver(new ResolverWidget(this));
X509Certificate cert = signature.getKeyInfo().getX509Certificate();
signature.checkSignatureValue(cert);
Now, I want to implement it in C++. I've tried Apache Santuario XML security for C++, but it failed because it said that it doesn't support c14n11 (I hope I'm wrong). So, I changed to use libxmlsec1, but the problem is I don't know how to implement with libxmlsec1. It doesn't have to verify all the files of Reference element. I just want to verify SignedInfo element. I've only done the following code.
xmlDocPtr doc = xmlParseFile("signature.xml");
xmlNodePtr node = xmlSecFindNode(xmlDocGetRootElement(doc), xmlSecNodeX509Certificate, xmlSecDSigNs);
xmlNodePtr data = node->children;
mngr = xmlSecKeysMngrCreate();
xmlSecCryptoAppDefaultKeysMngrInit(mngr);
xmlSecCryptoAppKeysMngrCertLoadMemory(mngr, data->content, size, xmlSecKeyDataFormatPem, xmlSecKeyDataTypeTrusted);
It fails with the following errors:
func=xmlSecOpenSSLAppCertLoadBIO:file=app.c:line=1254:obj=unknown:subj=PEM_read_bio_X509_AUX:error=4:crypto library function failed:
func=xmlSecOpenSSLAppKeysMngrCertLoadBIO:file=app.c:line=1139:obj=unknown:subj=xmlSecOpenSSLAppCertLoadBIO:error=1:xmlsec library function failed:
func=xmlSecOpenSSLAppKeysMngrCertLoadMemory:file=app.c:line=1091:obj=unknown:subj=xmlSecOpenSSLAppKeysMngrCertLoadBIO:error=1:xmlsec library function failed:
Please does anyone know how to make xmlsec1 read all the x509Certificate elements from the signature.xml, and verify signature.xml?
The following is signature.xml.
