能够在Java中验证SAML2.0令牌的数字签名。使用下面的代码段。
DOMValidateContext valContext = new DOMValidateContext(new X509KeySelector(), nl.item(0));
//Unmarshaling the XML Signature
XMLSignatureFactory factory = XMLSignatureFactory.getInstance("DOM");
XMLSignature signature = factory.unmarshalXMLSignature(valContext);
//Validating the XML Signature
boolean coreValidity = signature.validate(valContext);
if (coreValidity == false) {
System.err.println("Signature failed");
} else {
System.out.println("Signature passed");
}
if(!coreValidity){
boolean sv = signature.getSignatureValue().validate(valContext);
Iterator i = signature.getSignedInfo().getReferences().iterator();
for (int j=0; i.hasNext(); j++) {
boolean refValid = ((Reference)i.next()).validate(valContext);
}
}
然而无法在Java中验证SAML1.1令牌的数字签名。 •参考验证（签名中每个参考文摘的验证）失败 •签名验证（签名的加密验证）失败
需要帮助才能解决此问题。
使用下面的代码段
解决了这个问题NodeList assertnode = doc.getElementsByTagNameNS("urn:oasis:names:tc:SAML:1.0:assertion", "Assertion");
NamedNodeMap attrStore = assertnode.item(0).getAttributes();
System.out.println("ID - " + attrStore.getNamedItem("AssertionID").getNodeValue());
IdResolver.registerElementById(doc.getDocumentElement(), attrStore.getNamedItem("AssertionID").getNodeValue());
以下抛出异常
