[Opensc-devel] GIDS cards => need to add a new file type

[Vincent Le T. <vin...@my...>]

Hi,

I'm working on adding GIDS cards. This card is defined in a Microsoft
specification.
https://msdn.microsoft.com/en-us/library/windows/hardware/dn642100%28v=vs.85%29.aspx

The main advantage of this card is that it is the only card (except PIV
cards) coming with a native minidriver (it do not need anything to be used
immediately) and it is read/write with the minidriver.
What is unusual is that it is not a PKCS#15 card and it uses BER TLV files
defined in the iso 7816-4:2013.

The BER TLV file is not known / defined in OpenSC.
This is a new value of the file descriptor byte (added in iso 7816-4:2013
7.4.5) whose value is: 0x39 (111001). (the second file type added is SIMPLE
TLV structure)
Then each data is stored in a DO of this BER TLV file and is accessed with
a GET DATA / PUT DATA ADPU.

I would like to modify the sc_path_t structure to add a new type named
SC_PATH_TYPE_FILE_ID_DO and modify the sc_pkcs15_read_file like functions
to use getdata instead of read binary / read record when accessing data.
=> is it ok for you or do you have any comment ?

Thanks in advance for your attention

regards,
