NAME

pcsc−spy − A PC/SC spy command

SYNOPSIS

pcsc−spy [−n|−−nocolor] [−d|−−diffable] [−h|−−help] [−v|−−version] [−t|−−thread] [fifo_filename]

DESCRIPTION

pcsc−spy displays PC/SC calls of an application. It must be used with the libpcscspy.so.0 library.

To be able to spy the PC/SC layer, the application flow must be modified using "LIBPCSCLITE_DELEGATE" so that all PC/SC calls are redirected.

OPTIONS

−d, −−diffable

Remove the variable parts (like handler values) from the output so that two execution can be more easily compared.

−h, −−help

Display a short help text.

−n, −−nocolor

Disable the output colorization (if you want redirect the output in a file for example).

−v, −−version

Print the version of the pcsc−spy program plus a copyright, a list of authors.

−t, −−thread

Add a thread number before each line of log to identify the calls from the same threads.

EXAMPLES

We will use the "LIBPCSCLITE_DELEGATE" environment variable to load our spying library.

Example:

sh /usr/share/doc/libpcsclite−dev/setup_spy.sh
export LIBPCSCLITE_DELEGATE=/lib/x86_64−linux−gnu/libpcscspy.so.0
LIBPCSCLITE_DELEGATE=/lib/x86_64−linux−gnu/libpcscspy.so.0 my_application

Starting the spy tool

pcsc−spy

If a command argument is passed we use it instead of the default ˜/pcsc−spy FIFO file. It is then possible to record an execution log and use pcsc−spy multiple times on the same log.

To create the log file just do:

mkfifo ˜/pcsc−spy
cat ˜/pcsc−spy > logfile

and run your PC/SC application.

FILES

˜/pcsc−spy FIFO file is used by libpcscspy.so.0 to send the raw log lines
