Each sector of a MIFARE Classic card has two authentication keys: key A and key B. These two keys together with access conditions are stored in the last block of each sector (the so-called sector trailer).
I am using a Mifare classic 1k reader, and it comes with the default key A and B which is: FFFFFFFFFFFF. Using the Key A to read and write works. but I want to change the keys. Is there anyway to get the correct access bits for the sector and what is the format? What I have done now is, + access bits + Each sector of a MIFARE Classic card has two authentication keys: key A and key B. These two keys together with access conditions are stored in the last block of each sector (the so-called sector trailer). The sector trailer looks like this: if key B is used as an authentication key at all.
I have an empty Mifare Classic card and want to encrypt memory in just one sector by changing the key for that sector. However since this is an empty card all sectors have the default key FF FF FF FF FF FF.With MIFARE 1K and 4K cards, access to a sector’s data may require one or two authentication keys. These keys (KeyA and KeyB) can be configured for each card type. The keys can be expressed as either an ASCII character string or as binary value hex pairs indicated by the KeyType setting:
The Mifare Classic 1k RFID tag is a small, low-energy, passive, RFID tag. It gets it's power inductively from the reader/writer while it is inside the effective range (usually a few centimeters). It contains a small on-board IC which handles the anti-collision, authentication handshake, and encryption on the tag side of the interaction. I'm new to reading MIFARE Classic cards and wondering how to access each sector with Key A (A0A1A2A3A4A5) and a given Key B (which remains secret).

Re: How to change Key A and Key B in Mifare Classic 1k Yes you can add your known keys to the "default_keys.dic" file and then use the "Hf mf chk *1 ? default_keys.dic" command.
