In OpenSC the pkcs15-init part is used mostly by cards that can natively support the on-card PKCS#15 file system. The only exception is the Oberthur's card, that has producer specific on-card file system and data encoding. In the OpenSC this card uses the emulator in its 'pkcs15-libopensc' part (like the openpgp card), and uses extended pkcs15init API to implement the emulator of 'pkcs15-init' part . The 'emulator' extension of the pkcs15init API consists in the 'emu_*' sc_pkcs15init_operations handlers (src/libopensc/pkcs15-init.h). You can look into oberthur.profile and src/pkcs15init/pkcs15-oberthur.c with the card's pkcs15init handlers. No look too close into the src/pkcs15init/pkcs15-oberthur-awp.c. This file contains the implementing of the producer specific data encoding/decoding. Unfortunately there is no more or less full documentation on the profiles, other then the comments in profile files itself or in the sources. Kind regards, Viktor. _______________________________________________ opensc-devel mailing list opensc-devel@lists.opensc-project.org http://www.opensc-project.org/mailman/listinfo/opensc-devel
