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 |EAC| including |PACE|
- German electronic passport (ePass) with basic access control
- 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
================================================================================
First 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.
