Converts a list of MIFARE classic 4K B keys to mfd format.
Usage:
./mfd-converter.py b_keys.txt b_keys.mfd
The input file needs to be in this format:
000000000000
000000000000
000000000000
This is a very basic script that requires you to give all the B keys as input. It is based on the memory layout of the MIFARE Classic 4K, therefore it will not work with other types of card.
