Jochen Wiedmann closed XMLRPC-88:
---------------------------------
Resolution: Invalid
I cannot see, why this would be an issue for Apache XML-RPC. I suggest using a
forum on java.sun.com, or a mailing list related to encryption.

> Hello,
> I am trying to encrypt a XML file using XMLCipher class. The size of the file
> is almost 35 MB, while encrypting the XML file it throws this error after
> around 3 minutes.
> The program works perfectly fine for file size of less than 5 MB. This is
> very critical for our project and has to work as soon as possible.
> Eventually we are going to port the application on AIX5.3
> The piece of code I am using is:
> public void encryptData() throws EncryptionException
> {
> final String methodName = "encryptData";
>
> XMLCipher keyCipher,xmlCipher = null;
> Document document = null;
> String encryptedFileName = null;
> Key symmetricKey = null;
> Key keyEncryptKey = null;
> boolean exceptionOccured = false;
>
> try
> {
> System.out.println("now parsing document");
> document=parseFile( fileToBeEncrypted );
> // generate symmetric key
> symmetricKey = GenerateSymmetricKey();
>
> // Get a key to be used for encrypting the symmetric key
> keyEncryptKey = GenerateKeyEncryptionKey();
>
> // Write the key to a file
> //and pass the key and the name of file in which it has
> to store the Key
>
> storeKeyFile(keyEncryptKey,getKeyFileName(fileToBeEncrypted.toString()));
>
>
>
> // initialize cipher and operation mode is to wrap a key
> keyCipher
> =XMLCipher.getInstance(XMLCipher.TRIPLEDES_KeyWrap);
> keyCipher.init(XMLCipher.WRAP_MODE, keyEncryptKey);
>
> // encrypt symmetric key
> EncryptedKey encryptedKey =
> keyCipher.encryptKey(document, symmetricKey);
> // specify the element to encrypt, ideally it will be
> root element
> Element rootElement = document.getDocumentElement();

> Element elementToEncrypt = rootElement;

> if (elementToEncrypt == null)

> throw new EncryptionException("Element to Encrypt is
> null since the filename may not be correct" +
