pyDESFire

Desfire card library for Python

WARNING

Project still ongoing, use it with caution!

Features

• Compatible with all readers supported by pySCARD

• Pure python implementation

• One of the few DESFire libraries that supports ALL (DES,2DES,3DES,AES) authentication types

• Enumeration of the card gives an overlook on how the card is structured

Issues

• CMAC calculation fails (this causes the IV for the session key to lose sync with the IV on the card)

• Encrypted communication is not implemented (need to fix CMAC first)

• Can’t read data from certain file types

• Some commands are missing (since there is no full documentation available)
