Hello again. I'm going to start a project in wich I need to have interoperability between smart cards. Since not all cards are supported by OpenSC I would like some advice on the ideas I already have:
1) I've been studying PKCS#11 interface and it's interation with LIBP11 and I find out a good starting point there. Since I need more functions that are implemented by LIBP11 and opensc-pkcs11.so (like destruction of objects, keys and certificates) my idea is to extend LIBP11 with new functions and use private implementations of PKCS#11, since LIBP11 already provide an easy way to load PKCS#11 modules. By doing so, after a card is inserted, I could load and try a set of modules and find the correct one for the card inserted and use it. I've tested the LIBP11 examples with libaetpkss.so (the PKCS#11 module of starcos cards) and worked well. If I do that I might contribute with LIBP11 project by adding new functions to it. 2) My second approach, and maybe harder, is to work directly with winscard interface, using pcsc-lite implementations. I think I will stuck in this approach because, as far as I know, there are some default APDU's that work with every card, but there's a lot that differ from card to card. My main question is: if I initialize a PKCS#15 structure using pkcs15-init --create-pkcs15 will I have a default set of APDU's? Regards
