pyDESFire

Desfire card library for Python

WARNING

Project still ongoing, use it with caution!

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

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)
