This is a simple smartcard shell that has evolved from a more convenient way
|

to enter APDUs (compare: pcsc-tool scriptor) through a tool to open a secure
|
||||
to enter APDUs (compare: pcsc-tools scriptor) through a tool to open a secure
|
||||
channel to a cyberflex card (hence the name) to a more generic tool to act
|
||||
on smart-cards.
|
||||

||||
It is written in Python (you might need 2.4 or up) and needs pycsc to
|
||||
communicate with the smart card terminal (with PC/SC, e.g. pcsc-lite).
|
||||
It is written in Python (you might need 2.4 or up) and needs pycsc 0.3 (or up)
|
||||
to communicate with the smart card terminal (with PC/SC, e.g. pcsc-lite).
|
||||
You can get pycsc from http://homepage.mac.com/jlgiraud/pycsc/Pycsc.html
|
||||
|
||||
NOTE: pycsc might not compile out of the box with current pcsc-lite (e.g.
|
||||
1.3.*). You should use the included pycsc-0.0.3_new-pcsc.patch in that
|
||||
case.
|
||||
|
||||
The shell has only been tested on a Linux system but should be platform
|
||||
independent, if you have Python, PC/SC and pycsc for your target platform.
|
||||
I am however unable to give support for any platform but Linux.
|
||||
|
||||
Some of the shell functionality (history, tab-completion, etc.) is
|
||||
provided by python's readline module which is not available for all
|
||||
platforms, IIRC.
|
||||
|
||||
|
||||
INSTRUCTIONS:
|
||||
Simply start cyberflex-shell.py. You may also call it with parameter -l
|
||||
to list all detected readers or parameter -r to select one of the readers.
|
||||
Within the shell you may enter APDUs (in hex, case ignored, white space
|
||||
ignored) and press enter to send them and see the response.
|
||||
|
||||
Use the commands connect, disconnect or reconnect to open, close or open-
|
||||
and-close the connection to a smart-card. This is especially helpful when
|
||||
you want to change the card without exiting from the shell.
|
||||
|
||||
For some card types there are card drivers provided in the cards/ directory,
|
||||
and the shell will try to automatically load the right driver(s). (I made
|
||||
the story rather complicated, see cards/__init__.py.)
|
||||
You should be able to load and unload drivers using the driver_load and
|
||||
driver_unload commands at will, but that is a new and experimental feature.
|
||||
|
||||
Most card drivers provide additional commands to simplify working with
|
||||
the card in question. Use the help command to see the set of currently
|
||||
available commands.
|
||||
|
||||
Note that this is an educational tool and not for security purposes. All
|
||||
commands are written to the shell history (${HOME}/.cyberflex-shell.history)
|
||||
so be aware that your PINs and other sensitive data might end up on your
|
||||
hard-disk.
|
||||
|
||||
Have fun
