You have correctly identified the required data. Feed it into tools/mfkey/mfkey64
The ! Indicate parity errors.. These are expected for encrypted data.

Thank you for your answer, I'm just starting.
Can you explain me in detail, how to find and use mfkey64 ?
I saw a command "decrypt" in iceman library, can you use that to decrypt the key ?
What is the syntax ?

You have mfkey64 already. It is part of the proxmark repository. It is in directory tools/mfkey.
