Hello,
> Actually - who makes this software: > pcsc_create_dir_crycs() > > that does those commands ? that command creates a file ( DF or MF ) with cryptographic checksum. On the GPK-cards "secure messaging" can be used for communication. That means that you can create a temporary session key (DES) with that there is a checksum calculated over the command bytes. So one can be shure that the answer "really" comes from the card and is not corrupted in any way. I have copied the code from an example out of the SCEZ library and ported it to PC/SC in order to test the card and get used to smartcard programming. If you are interested I can send you the GPK Reference Manual where "secure messaging" is descibed in detail?
