desfire-tools-for-android

A collection of tools for interaction with MIFARE DESFire EV1 NFC tags using Android, mostly adapted from libfreefare and nfcjlib.

Notes from MichaelsPlayground & AndroidCrypto

Note: This repository was forked from the original source available at:

https://github.com/skjolber/desfire-tools-for-android by Thomas Skjølberg (skjolber)

I changed as less as necessary to get the app run on modern Android SDK's - this app is running on SDK 33 and Gradle version 7.4.2. I know that there are a lot of "deprecated" notices in the source code but that could be the task for further enhancements. All credits are going to Thomas Skjølberg who created this fine piece of app in helping us to work with Mifare DESFIRE EV1 cards (b.t.w. the app is working on DESFire EV2 and EV3 as well :-).

One note regarding the file "MifareDesfireKey1.java" located in com.github.skjolber.desfire.libfreefare. The file equals to "MifareDesfireKey.java" in the original repository but as there is another file named "MifareDESFireKey.java" (see the capitol letters "DES" compared to "Des") only one file can exist in a MacOS file system (I don't know about Windows, sorry). I renamed the file from "MifareDesfireKey.java" to "MifareDesfireKey1.java" and changed all references in the code to the new file name.

Second note: I included the "libfreefare" and "model" libraries direct into my package so they are no included within the build.gradle (app) file.

The original description follows...

The original app in Google PlayStore: https://play.google.com/store/apps/details?id=com.skjolberg.mifare.desfiretool&hl=no

Features:

MIFARE DESFire EV1 tag model
Encryption support

Mifare Desfire Tool demo application

As NXP now has a freely available TapLinx SDK for supporting these cards, so this project is mostly for educational and/or debugging purposes.
