This is the major changes made to the HITAG2 commands. Its heavly based on RFIDLers implementation and its been converted to work with Proxmark3. Special thanks to @kevsecurity for his amazing implementations of the Gone in 360 Seconds paper by Roel, Flavio & Balasch. Thanks to @adamlaurie for his RFIDler project. It wouldnt been doable without it.
