[Opensc-devel] IAS/ECC, iasecc_select_mf and AID

[Kaspars D. <ka...@da...>]

Hello!

I'm trying to understand why this legacy version of OpenSC [1] is able to
recognize my Latvia eID card (IAS/ECC) while my efforts of porting the
support for the card to the latest version of OpenSC [2] is currently
failing.

Here is the relevant debug log from both versions:
https://gist.github.com/kasparsd/66cf8b145b7e3ae8d120

It appears that iasecc_select_mf is using the wrong file path after having
received the same APDU response. The working version selects the following:

> card-iasecc.c:603:iasecc_select_file:
iasecc_select_file(card:0x1018005e0) path.len 16; path.type 1; aid_len 0
> card-iasecc.c:604:iasecc_select_file: iasecc_select_file()
path:a000000077010800070000fe00000100::

while the non-working version does this:

> card-iasecc.c:943:iasecc_select_file:
iasecc_select_file(card:0x7ffd94801000) path.len 10; path.type 1; aid_len 0
> card-iasecc.c:944:iasecc_select_file: iasecc_select_file()
path:4c41545649412d654944::

I would appreciate any tips or suggestion on where to put debug pointers to
be able to resolve this. Here are the complete logs [3] if that would help.

Thanks!
Kaspars

p.s. please note that I've spent only a few month looking into smart cards
and have a very basic understanding of C.
