In last couple months while learning to develop Java Card applets I managed to develop ISO 7816 compatible file system applet. I successfully implemented most of the standardized APDU commands from 7816-4, -8, -9 standards (I used other available functional descriptions and standards like OpenPGP applet, IAS ECC, MUSCLE, CoolKey etc. to help me understand former standards).
Now I am trying to develop PKCS#11 implementation for this my own applet. I am familiar with using OpenSC tools for already supported cards (opensc-tool, opensc-explorer, pkcs15-init, pkcs15-tool etc.). But I would like to develop driver for this applet for OpenSC.
I browsed information available on their project site on github and found some documentation on implementing custom driver for OpenSC (entersafe card example, and general suggestions for card driver implementation). Also I found that on gooze.eu there were available some tutorials on OpenSC, but this site is no longer available.
So my questions are:
- Where can I find some more information on OpenSC API in order to understand available driver code and to manage to develop my own?
- Any general overview of API, about OpenSC architecture, description of available functions (description on intended usage of structures and functions such as sc_format_apdu, sc_transpit_apdu, sc_card_operatins as an example etc.) to give me a jumpstart for understanding OpenSC source code and implementing a card driver.
- Are there any man pages for OpenSC API (googling I was able to find some, but very incomplete and sporadic).
Any information would be very helpful.
