Your use of the ebXML protocol assumes you are also using its cryptographic features (encryption, decryption, signatures, and verifications). Additional steps are required in setting up the eXchange service to use these features.
You must associate encryption information with each XDC eXchange service. For complete information on setting up an eXchange service with cryptographic features for Protocol Managers, see the eXchange Integrator User’s Guide. For specific examples, see the encryption setup used in the sample Project explained in Run-time Steps.
