Hi Colm,
Thank you for the reply.
As per decryptUsingStAX method in EncryptionUtils class I tried to code
something similar but it returns a document object rather void:
public static Document decryptUsingStAX(InputStream inputStream,
List<QName> namesToEncrypt, Key privateKey) throws
Exception {
// Set up the Configuration
XMLSecurityProperties properties = new XMLSecurityProperties();
List<XMLSecurityConstants.Action> actions = new
ArrayList<XMLSecurityConstants.Action>();
actions.add(XMLSecurityConstants.ENCRYPT);
properties.setActions(actions);
properties.setDecryptionKey(privateKey);
InboundXMLSec inboundXMLSec =
XMLSec.getInboundWSSec(properties);
XMLInputFactory xmlInputFactory = XMLInputFactory.newInstance();
final XMLStreamReader xmlStreamReader = xmlInputFactory
.createXMLStreamReader(inputStream);
TestSecurityEventListener eventListener = new
TestSecurityEventListener();
XMLStreamReader securityStreamReader =
inboundXMLSec.processInMessage(
xmlStreamReader, null, eventListener);
while (securityStreamReader.hasNext()) {
securityStreamReader.next();
}
xmlStreamReader.close();
inputStream.close();
// Check that what we were expecting to be encrypted was
actually
// encrypted
List<EncryptedElementSecurityEvent> encryptedElementEvents =
eventListener
.getSecurityEvents(SecurityEventConstants.EncryptedElement);
for (int i = 0; i < encryptedElementEvents.size(); i++) {
System.out.println(i + ": " +
encryptedElementEvents.get(i));
}
for (QName nameToEncrypt : namesToEncrypt) {
boolean found = false;
for (EncryptedElementSecurityEvent encryptedElement :
encryptedElementEvents) {
if (encryptedElement.isEncrypted()
&& nameToEncrypt
.equals(getEncryptedQName(encryptedElement
.getElementPath()))) {
found = true;
System.out.println("nameToEncrypt " +
nameToEncrypt);
break;
}
if (!found) {
throw new Exception("Element not
found");
}
}
}
Document document = StAX2DOM.readDoc(
XMLUtils.createDocumentBuilder(false),
securityStreamReader);
return document;
}
Now, in my main method I have instructions like:
// Decrypt
Key privateKey = keyStore
.getKey("myservicekey", "skpass".toCharArray());
ByteArrayInputStream bais = new
ByteArrayInputStream(baos.toByteArray());
Document result = EncryptionUtils.decryptUsingStAX(bais,
namesToEncrypt, privateKey);
// check decrypt done successfully
String resultString = getStringFromDocument(result);
System.out.println("result:\n" + resultString.toString());
The method getStringFromDocument is a helper method
public String getStringFromDocument(Document doc) {
try {
DOMSource domSource = new DOMSource(doc);
StringWriter writer = new StringWriter();
StreamResult result = new StreamResult(writer);
TransformerFactory tf =
TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.transform(domSource, result);
return writer.toString();
} catch (TransformerException ex) {
ex.printStackTrace();
return null;
}
}
The output is:
result:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
Apologies if the question looks stupid but I am really struggling to figure
out the way to achieve the task, I would appreciate your assistance.
Thanks very much in advance,
Regards
Mujahed
