Matthieu,

   I am working on the following issue you reported.

        110080418016869
        [MS-BKRP]  3.1.4.1.3 -- version field and a GUID field no documented

        Also I've got questions of what is explained in the document.

        First  in paragraph 3.1.4.1.3, it is stated

        "The server MUST ignore the cbDataIn and pDataIn parameters. It MUST
        return the RSA public key
        from the ClientWrap key pair, in the format specified in section 2.2.1.
        If no such key can be found or
        created, the server MUST return an error."

        The client is supposed to send a 2.2.2 Client-Side-Wrapped Secret struct
        in the pDataIn variable, this struct contains also a version field and a
        guid field.
        Nothing is said about this fields, how should they be populated, can you
        explain this ?


     I think that there may be something mixed up here.  The paragraph 
3.1.4.1.3 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.

    Please confirm.
Ah yeah It seems that I get confused.
Thanks!
