Help!!!! SignatureValue Mismatch

[NeilReed]

Hello,

For reasons I can not control I am having to compose some code to talk to a b2b ebxml system.

There is no WSDL so Im having to code it all.

The posts are made via HTTP using SOAP with an XML payload.

Step 1:

Generate Digest Value of the SOAP document using an enclosingTransform.

Step 2:

Generate the Digest Value of the Payload document (Not enclosing)

Step 3:

Add the Digest Values to the SignedInfo Template (Inlcuding relivent references)

Step 4:

Generate the Signature value from the SignedInfo XML (This is done by using a X509 cert and the microsoft SignedXML)

Step 5: Add the SignatureValue to the SignedInfoTemplate.

Step 6: Import/ Append the XML to the SOAP

Step 7: Transmit the data via a HTTPWebRequest

The problem is that the SignatureValue seems to be a mismatch when calculated at the other end.

Any help would be welcomed.
