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 |vpcd| opens slots for communication with multiple |vpicc|'s on
localhost from port 35963 to port 35972. 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_.

.. versionadded:: 0.7
We implemented |vpcd| as user mode device driver for Windows so that
|vpicc| can directly be used in Windows' smart card applications that use
PC/SC.
.. versionadded:: 0.7
The Virtual Smart Card optionally brings its own standalone implementation of
PC/SC. This allows accessing |vpicc| without PCSC-Lite. Our PC/SC
implementation acts as replacement for ``libpcsclite`` which can lead to
problems when used in parallel with PCSC-Lite.

Depending on your usage of the |vpicc| you might or might not need
the following:
- Python_
- pyscard_
- PyCrypto_
- PBKDF2_
- PIP_
- OpenPACE_ (nPA emulation)
================================================================================
Building and installing |vpcd| on Windows
================================================================================
For the Windows integration we extended `Fabio Ottavi's UMDF Driver for a
Virtual Smart Card Reader`_ with a |vpcd| interface. To build the |vpcd| we use
`Windows Driver Kit 8.1 and Visual Studio 2013`_:
1. In Visual Studio select :menuselection:`File --> Open --> Convert
Sources/Dirs...` and choose the vpcd's :file:`sources` either in the
:file:`WinXP` or :file:`Win7` folder.
2. If you can successfully :guilabel:`Build the solution`, you can find the
install package in :file:`BixVReader-package`. It contains `BixVReader.inf`
and the required libraries, especially `BixVReader.dll`.
3. Copy :file:`win32\\BixVReader\\BixVReader.ini` into the :envvar:`%SystemRoot%`
directory.
4. In a console with administrator rights go to :file:`BixVReader-package` and
execute::
"C:\Program Files\Windows Kits\8.1\Tools\x86\devcon.exe" install BixVReader.inf root\BixVirtualReader
You can adjust the path to ``devcon.exe`` with your version of the WDK and
your target architecture.
For debugging |vpcd| and building the driver with an older version of Visual
Studio or WDK please see `Fabio Ottavi's UMDF Driver for a Virtual Smart Card
Reader`_ for details.
********************************************************************************
Using the Virtual Smart Card
********************************************************************************
The protocol between |vpcd| and |vpicc| as well as details on extending |vpicc|
with a different card emulator are covered in :ref:`virtualsmartcard-api`. Here
we will focus on configuring and running the provided modules.
================================================================================
Configuring |vpcd| on Unix
================================================================================
The configuration file from |vpcd| is usually placed into
:file:`/etc/reader.conf.d/`. The PC/SC daemon should read it and load the
|vpcd| on startup. In debug mode :command:`pcscd -f -d` should say something
like "Attempting startup of Virtual PCD". For older versions of PCSC-Lite you
need to run :command:`update-reader.conf` to update :command:`pcscd`'s main
configuration file.
By default, |vpcd| opens a socket for |vpicc| and waits for incoming
connections. The port to open should be specified in ``CHANNELID`` and
``DEVICENAME``:
.. literalinclude:: vpcd_example.conf
:emphasize-lines: 2,4
If the first part of the ``DEVICENAME`` is different from ``/dev/null``, |vpcd|
will use this string as a hostname for connecting to a waiting |vpicc|. |vpicc|
needs to be started with :option:`--reversed` in this case.
================================================================================
Configuring |vpcd| on Windows
================================================================================
The configuration file from |vpcd| is usually placed into
:file:`C:\\Windows`. The PC/SC daemon should read it and load the
|vpcd| on startup. The Windows Device Manager should list the :guilabel:`Bix
Virtual Smart Card Reader`.
|vpcd| opens a socket for |vpicc| and waits for incoming
connections. The port to open should be specified in ``TCP_PORT``:
.. literalinclude:: BixVReader.ini
:emphasize-lines: 8
Currently it is not possible to configure the Windows driver to connect to an
|vpicc| running with :option:`--reversed`.
================================================================================
Running |vpicc|
================================================================================
The command :command:`vicc --help` gives an overview about the command line
options of |vpicc|.
.. program-output:: vicc --help
When |vpcd| and |vpicc| are connected you should be able to access the card
through the PC/SC API via :command:`pcscd`. You can use the
:command:`opensc-explorer` or :command:`pcsc_scan` for testing. In
Virtual Smart Card's root directory we also provide scripts for testing with
:ref:`libnpa` and PCSC-Lite's smart card reader driver tester.
