Description
It would be nice to have a script that allow to bruteforce master password of
https://github.com/JeNeSuisPasDave/authenticator
it uses the AES 256-bit symmetric key:

to encrypt the second 16-byte data and compare it with the first 16-byte block (header):

Research direction
Start with the linked authenticator/src/authenticator/data.py sections at lines 597-606 and 802-807 to understand the key and block comparison, then inspect John the Ripper's existing format and extractor entry points. Done means adding support for the authenticator data and the described master-password comparison.
