XML encryption with key encryption

[Jobbagy Peter <jo...@mail.datanet.hu>]

Hi people,

I used your package for xmldsig and it worked fine!
Now I using this for xml encryption (xmlenc).
I can encrypt/decrypt xml messages with the following methods:

Document cryptEN(Document doc,Key key)
  { try
    { EncryptedData enc=
        new EncryptedData(doc,
          EncryptionConstants.ALGO_ID_BLOCKCIPHER_TRIPLEDES,
          null,null,null,null);
      enc.encryptElementAndReplace(doc.getDocumentElement(),key);
    } catch (Exception e) { }
    return (doc);
  };

  Document cryptDE(Document doc,Key key)
  { try
    { EncryptedData enc=
        new EncryptedData(doc.getDocumentElement(),"");
      enc.decryptAndReplace(key);
    } catch (Exception e) { }
    return (doc);
  };

Now I want to extend the methods above to embed the encryption key (perhaps
with EncryptedKey class?)
with the method of "EncryptionConstants.ALGO_ID_KEYTRANSPORT_RSA1_5".
I tried it already but I couldn't find the exact way how to make it.
Can anybody help me? How is the EncryptionKey is related with the
EncryptionDocumet?

Thanks for all,
Peter

Jobbagy and others,

Am not clear where this EncryptedData comes from?  Is there something in 
the library over and above Axl's code?

Cheers,
