This is a pure python version of the javacard operating system as found on javacard smartcards.

It does not provides much on his own beside the functionnalities of the Operating System, as such, it is often used in combinason with others projects like CAPRunner (linked with CAP files) or WebSCard (through CAPRunner or python versions of Applets)

Documentation on this project is better found as original JavaCard documentation (ask Google). The goal is to replication the exact same functionnalities. If your experience is other, please fill in a bug report. Same for missing functionnalities.

To use it, when writing your Applet, just replace the following Java construction:

import javacard.framework.Applet;

with:

from pythoncard.framework import Applet

As, so far I know, the javacard version are backward compatible, the goal is to provide a classic 3.0.1 version, while maintaining compatiblity with earlier version like 2.1.2.

PythonCard is dependant on pyDes and pyCrypto for crptographic operations. The rest of the functionnalities will however work without those packages installed.
