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
