 ```shell
 $ python3 get_encryption_key.py MAC USERNAME
-Key ID: xx
-Encryption key: xxxxxxxxxxxxxxxx
+Key ID: XX
+Encryption key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
 ```
 
 Where `MAC` is MAC address of the lock and `USERNAME` is your SwitchBot account username, after that script will ask for your password.
 If authentication succeeds then script should output your key id and encryption key.
