Hi Dobri, <encryptionUser>useReqSigCert</encryptionUser> > > My question is is it possible to use this with Symmetric binding?
Good question. When a symmetric binding is used encrpted key is created and that encrypted key is used to sign and encrypt the messages back and forth. So we won't be able to get the certificate that used to sign the message as the message is signed using the encrypted key not the initiators signature. But it won't be a problem as in Symmetric binding case we don't need the initiators certificate to encrypt the message as the message is encrypted using the encrypted key. And one more thing. If the policy specifies an endorsing supporting token or signed endorsing supporting token, then the message signature signed using the endorsing supporting token. In that case, we use initiator certificate (if the supporting token is a X509 cert) to sign the message signature. However we don't need this certificate to encrypt the message back to the initiator as encrypted key is used for that purpose. Regards, Nandana > > > Thank you. > > Best regards, Dobri >
