Hi,
The UEFI specification (version 2.5) describes EFI_SMART_CARD_EDGE_PROTOCOL's 'GetData' function as follows - "The function is generic for any kind of data, but driver and application must share an EFI_GUID that identify the data." One of the input parameters of this function is 'DataId', which is of type 'EFI_GUID', and is used to define type of data to be retrieved. The question is - how to share the EFI_GUID based information between the driver and the application? The other functions of this protocol does not provide any way to share such information. Is there any standard mapping / information available for such EFI_GUIDs? [ Note: There are couple of functions in this protocol (i.e. 'SignData' and 'DecryptData'), which also accepts EFI_GUID parameters. However, the expected EFI_GUID values of these parameters have been defined in the UEFI specification along with the function description. ] I believe, the GetData function can expect Object IDs of the objects present on the SmartCard to retrieve related data. Hence, it might be helpful to have a mapping between these OIDs and EFI_GUIDs. However,these Object IDs could be different for different type of cards (i.e. PIV, openPGP etc), which makes it difficult to pre-define them in Spec. But how this information can be shared between driver and the app? Is it expected to have EFI_GUIDs defined per SMART_CARD_EDGE _PROTOCOL implementation and shared using common header file? I am a newbie in EDK and Smart Card development. All comments and suggestions are very much appreciated.
