Hi, I'm having some encryption problems...
I'm trying to encrypt the contents of a SOAPBody of a SOAPEnvelope using
TRIPLEDES and AES_128. I tryed to follow the steps of the example in
org.apache.xml.security.samples.encryption
but I'm having problem in the some steps:
1. After the encryption how can I turn the resulting org.w3c.Document into
a SOAPEnvelope or SOAPMessage to sendo it to the web service server??? I
tryed this but it's not working...
"
org.w3c.dom.Document doc = soapEnv.getAsDocument();
Key symmetricKey = GenerateDataEncryptionKey();
Key kek = GenerateAndStoreKeyEncryptionKey();
String algorithmURI = XMLCipher.TRIPLEDES_KeyWrap;
XMLCipher keyCipher = XMLCipher.getInstance(algorithmURI);
keyCipher.init(XMLCipher.WRAP_MODE, kek);
EncryptedKey encryptedKey = keyCipher.encryptKey(doc, symmetricKey);
Element rootElement = doc.getDocumentElement();
algorithmURI = XMLCipher.AES_128;
XMLCipher xmlCipher = XMLCipher.getInstance(algorithmURI);
xmlCipher.init(XMLCipher.ENCRYPT_MODE, symmetricKey);
EncryptedData encryptedData = xmlCipher.getEncryptedData();
KeyInfo keyInfo = new KeyInfo(doc);
keyInfo.add(encryptedKey);
encryptedData.setKeyInfo(keyInfo);
//xmlCipher.doFinal(doc, rootElement, true);
xmlCipher.doFinal(doc, doc);
Canonicalizer c14n = Canonicalizer
.getInstance(Canonicalizer.ALGO_ID_C14N_WITH_COMMENTS);
byte[] canonicalMessage = c14n.canonicalizeSubtree(doc);
InputStream is = new java.io.ByteArrayInputStream(canonicalMessage);
SOAPEnvelope env = new SOAPEnvelope(is);
"
The exception is:
org.xml.sax.SAXException: Bad envelope tag: EncryptedData
Thanks in advance for the help...
