Simple Caeser Cipher [En,De]coder

A simple implementation of a CLI tool to work with caeser ciphers. The default implementation is ROT-13, but can be adjusted for any offset. Works on files and string arguments passed via CLI.

python3 caeser.py

usage: caeser.py [-h] [-d] [-o OFFSET] (-f FILE | -s STRING)
caeser.py: error: one of the arguments -f/--file -s/--string is required

python3 caeser.py -s "have you tried turning it off and on again?"

have you tried turning it off and on again?

python3 caeser.py -s "have you tried turning it off and on again?" -o -4
