Delaying any attempt to do change key, until every basic operation has been explored and different configurations exercised.
Today, I am able to increase the utilization of every bit of the DESFire card settings according to its intended function. In summary, I am able to create a completely hidden application, containing one file of non-default access rights. So TagInfo is unable to read any information from the card:
I am also able to read back the secured content. Of note, is that previously I have been unable to achieve this desired configuration using skjolber
codebase due to a bug in its implementation it throws an exception saying No room for CMAC
message.
As I am following a systematic granular step-by-step progression to avoid accidentally bricking a card, the current configuration still uses 3DES
ciphers.
Basic security changes.
This will be both for PICC and application configuration.
