Virtual Smart Card emulates a smart card and makes it accessible through PC/SC.
|
|
Currently the Virtual Smart Card supports the following types of smart cards:
|
|
|
|
- Generic ISO-7816 smart card including secure messaging
|
|
- German electronic identity card (nPA) with complete support for |EAC| (|PACE|, |TA|, |CA|)
|
|
- German electronic passport (ePass) with complete support for |BAC|
|
|
- Cryptoflex smart card (incomplete)
|
|
|
|
The |vpcd| is a smart card driver for PCSC-Lite_. It allows
|
|
smart card applications to access the |vpicc| through the PC/SC API. By
|
|
default |vpicc| communicates with |vpcd| through a socket on localhost port
|
|
35963. But the |vpicc| does not need to run on the same machine as the |vpcd|,
|
|
they can connect over the internet for example.
|
|
|
|
Although the Virtual Smart Card is a software emulator, you can use
|
|
:ref:`pcsc-relay` to make it accessible to an external contact-less smart card
|
|
reader.
|
|
|
|
The file :file:`utils.py` was taken from Henryk Plötz's cyberflex-shell_.

|
Depending on your usage of the |vpicc| you might or might not need
|
|
the following:
|
|
|
|
- Python_
|
|
- pyscard_
|
|
- PyCrypto_
|
|
- PBKDF2_
|
|
- PIP_
|
|
|
|
The |vpcd| depends on PCSC-Lite_.

Running the Virtual Smart Card
|
|
******************************
|
|
|
|
Fitxt you need to make sure that :command:`pcscd` loads the |vpcd|. You might
|
|
need to run :command:`update-reader.conf` to update its configuration file.
|
|
Then :command:`pcscd -f -d` should say something like "Attempting startup of
|
|
Virtual PCD"
|
|
|
|
Now you can run :command:`vicc` which connects to the |vpcd|. The command
|
|
:command:`vicc --help` gives an overview about the command line options.
|
|
|
|
.. program-output:: vicc --help
|
|
|
|
You should now be able to access the |vpicc| through the PC/SC API via
|
|
|vpcd|/:command:`pcscd`. You can use the :command:`opensc-explorer` or
|
|
:command:`pcsc_scan` for testing.

==========================================================
|
|
Accessing the Virtual Smart Card from Windows applications
|
|
==========================================================
|
|
|
|
Running |vpcd| under Windows is currently not supported, because it implements
|
|
a smart card driver specific for PCSC-Lite (:command:`pcscd`). This means, that
|
|
although you can run |vpicc| under Windows (for example in relay mode), it
|
|
can't be accessed by Windows' smart card applications.
|
|
|
|
However, there are several more or less complicated paths you can go:
|
|
|
|
- Run |vpcd|/:command:`pcscd` in Linux and use :ref:`pcsc-relay` to forward the
|
|
|vpicc| via NFC to a contactless reader which is attached to the Windows
|
|
machine. This has been tested tested with a ACR122U (touchatag).
|
|
- Run your windows machine as virtual machine in a Linux host. Then run
|
|
|vpcd|/:command:`pcscd` in the Linux host and grab the |vpicc| with the
|
|
:ref:`ccid-emulator`. Now forward the emulated USB device to the Windows VM.
|
|
This is easy, but the :ref:`ccid-emulator` is not tested very well under
|
|
Windows.
|
|
- Use the combination above (|vpcd|/:ref:`ccid-emulator` under Linux) on a
|
|
device, that you can put in USB client mode. Then use a USB connector to
|
|
physically connect the Linux machine in client mode to the Windows machine.
|
|
- Port the |vpcd| from PCSC-Lite to Windows' PC/SC service. Then, |vpcd| runs
|
|
natively under Windows. Although |vpcd| is relatively simple and should be
|
|
POSIX compliant, this could be a lot of work.
|
|
- Run |vpcd|/:command:`pcscd` under Cygwin on the Windows machine. This has
|
|
been reported to work, but it is unclear whether you can use PCSC-Lite as
|
|
PC/SC provider for a native Windows application.
