Hi guys!
I have a problem... Working with a MIFARE 523 Reader and want to perform an 3DES authentication on a Ultralight C card.
My documentation says that there are two steps needed.
The first one is to send 0x1A 00 to the card.
Then the card answers with a specific token ek(RndB)
The next step is to send 0xAF and the randomly generated ek(RndA + RndB').
My question is: how do i get the token ek(RndA + RndB') which i need to send with the AF command?
I hope u can help me
with kind regards
