Useless Encryption

Requires Python 3.10.x or newer and implements useless encryption (aka, it's not thread-safe, it's not crypto-safe, please don't use it, I made it as a joke).

To encrypt a message:

python -m useless encrypt key message

To decrypt a message:

python -m useless decrypt key message

Note that you need to include quotes if either your key or your message contains a space. Example:

python -m useless <encrypt|decrypt> "key with spaces" "message with spaces"
