DESFire

Desfire card library for Python

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

• Functions implement:

  • authenticate
  • getApplicationIDs
  • getKeySetting
  • getCardVersion
  • formatCard
  • selectApplication
  • createApplication
  • deleteApplication
  • getFileIDs
  • getFileSettings
  • readFileData
  • writeFileData
  • deleteFile
  • createStdDataFile
  • getKeyVersion
  • changeKeySettings
  • changeKey

Issues

• Can’t read data from certain file types

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