I tried something like this (with apache xml signature):
public static boolean verify(Document doc) {
try {
// Initialize the library - this is now done inside servlet WSSInit
org.apache.xml.security.Init.init();
// must match baseURI
String baseURI = "PARes52524142080316501023";
CachedXPathAPI xpathAPI = new CachedXPathAPI();
Element nsctx = doc.createElement("nsctx");
nsctx.setAttribute("xmlns:ds", Constants.SignatureSpecNS);
Element signatureElem = (Element) xpathAPI.selectSingleNode(doc,
"//ds:Signature", nsctx);
// Check to make sure that the document claims to have been signed
if (null == signatureElem) {
throw new IllegalStateException(
"SOAP Document not digitally signed - missing element: //
ds:Signature");
}
XMLSignature sig = new XMLSignature(signatureElem, baseURI);
X509Certificate cert=sig.getKeyInfo().getX509Certificate();
System.out.println(cert.getSubjectDN().getName());
boolean verify =
sig.checkSignatureValue(sig.getKeyInfo().getX509Certificate());
if (true == verify) {
System.out.println("verify ok");
return true;
}
} catch (Exception e) {
e.printStackTrace();
return false;
}
// signature verification failed -
// do not forward request to SOAP Service.
return false;
}
but I always get "- Verification failed for URI
"#PARes52524142080316501023"
I tried with java xmldigsig:
public static boolean verify(Document doc) throws Exception{
NodeList nl =
doc.getElementsByTagNameNS(XMLSignature.XMLNS, "Signature");
if (nl.getLength() == 0) {
throw new Exception("Cannot find Signature element");
}
// Create a DOM XMLSignatureFactory that will be used to unmarshal
the
// document containing the XMLSignature
String providerName = System.getProperty
("jsr105Provider",
"org.jcp.xml.dsig.internal.dom.XMLDSigRI");
XMLSignatureFactory fac = XMLSignatureFactory.getInstance("DOM",
(Provider) Class.forName(providerName).newInstance());
// Create a DOMValidateContext and specify a KeyValue KeySelector
// and document context
DOMValidateContext valContext = new DOMValidateContext
(new X509KeySelector(), nl.item(0));
// unmarshal the XMLSignature
XMLSignature signature = fac.unmarshalXMLSignature(valContext);
// Validate the XMLSignature (generated above)
boolean coreValidity = signature.validate(valContext);
// Check core validation status
if (coreValidity == false) {
System.err.println("Signature failed core validation");
boolean sv = signature.getSignatureValue().validate(valContext);
System.out.println("signature validation status: " + sv);
// check the validation status of each Reference
Iterator i =
signature.getSignedInfo().getReferences().iterator();
for (int j=0; i.hasNext(); j++) {
boolean refValid =
((Reference) i.next()).validate(valContext);
System.out.println("ref["+j+"] validity status: " + refValid);
}
return false;
} else {
System.out.println("Signature passed core validation");
return true;
}
}
but I always get "- Couldn't validate the References
Signature failed core validation"
In Java xmldigsig Javadoc I found an interface "URIDereferencer" that
can be implemented and set to DOMValidateContext:
valContext.setURIDereferencer(),
but I was not able to implement this interface.
I would prefer to use java xmldig sig rather than apache, but any
solution wold be nice.
Can anyone help?
Thanks,
Alan
