Define the hex pattern to search for (passcode verification and Keybag routines)

VERIFY_PASSCODE_PATTERN = b'\x4C\xF1' # Hypothetical passcode check function location (update with actual signature) KEYBAG_UNLOCK_PATTERN = b'\xAA\xBB' # Hypothetical keybag unlock function (update with actual signature) 

Define the "bypass" patterns
