> I think that there may be something mixed up here. The paragraph 188.8.131.52.3 is for sending BACKUPKEY_RETRIEVE_BACKUP_KEY_GUID to request the public key part of the server's ClientWrap key pair. Just as mentioned in your message, there should no input to pDataIn variable as well as cbDataIn, so I am not sure that the second paragraph is related to your question , unless you are talking about sending BACKUPKEY_RESTORE_GUID which requires clients to send Client-Side-Wrapped Secret structure.
> If this is the case, version field should be populated as either 2 or 3 based on the EncryptedSecret and AccessCheck fields (2.2.2 MS-BKRP). The guidKey should be populated using the unique GUID of the public key returned from BACKUPKEY_RETRIEVE_BACKUP_KEY_GUID request.
