crack mifare key used proxmark3


1. use hf mf chk to find default key.







2. use hf mf nested commands to crack all the keys, to use hf mf nested, we just need to know one sector' key, as found in the hf mf chk command.







3. use hf mf dump to dump the card.



now all is done, you can find dumpkeys.bin and dumpdata.bin two files in the proxmark3.exe directory, they are binary file. .
dumpdata.bin is the content of the mifare card
dumpkeys.bin is the keys of the mifare card, KeyA(0-15) KeyB(0-15)
