OpenSAML user discussion

[Deena Gurajala <>]

Hi,

Can anybody give me some direction on how to achieve Digital Signatures with XML encryption using openSAML? I am doing  in the following way.

Response response=getResponse();
Assertion assertion=getAssertion();

Signature signature=getSignature();
assertion.setSignature(signature);

EncryptedAssertion encAssertion=getEncryptedAssertion(assertion);
response.getEncryptedAssertion.add(encAssertion);

MarshallerFactory marshalFact = Configuration .getMarshallerFactory();
Marshaller marshaller = marshalFact.getMarshaller(response);
 Element responseElement = marshaller.marshall(response);

 Signer.signObject(signature);

This is Successful. I am able to generate the encrypted assertion as above. On the other end I am able decrypt the assertion.

After decrypting the assertion, I am trying to validate the signature. But it is not going through. I am always getting "Signature did not validate against the credential's key" Exception. 

What I am doing wrong? Can some body direct me to the correct path?
