usage: cipherctl.py [-h] [--debug]
                    {atbash,caesar,rot5,rot13,rot18,rot47,vigenere} ...

The cipherctl utility allows you to encode or decode in various ciphers

positional arguments:
  {atbash,caesar,rot5,rot13,rot18,rot47,vigenere}
                        ciphers
    atbash              Atbash cipher actions
    caesar              Caesar cipher actions
    rot5                ROT-5 cipher actions
    rot13               ROT-13 cipher actions
    rot18               ROT-18 cipher actions
    rot47               ROT-47 cipher actions
    vigenere            Vigenere cipher actions

optional arguments:
  -h, --help            show this help message and exit
  --debug               Enables verbose logging for cipherctl commands
