I am trying to update the access keys and access bits in Mifare Classic 1K card. My goal is to get the below behavior on sector 1 :
- Put a custom KEY-A. should be able to read / modify it later (after authenticating with KEY-A)
- The data in blocks 0..3 of sector 1 is RW using KEY-A only
- No read or write access using KEY - B
Based on this, I am using the mifare classic calculator on page at http://calc.gmss.ru/Mifare1k/ to come up with the following.
Can someone confirm if I got it right? Pretty new to RFID
