Originally this repository was for an assignment to impliment RC5 in my Computer Security course at the Univeristy of Guelph.
In the interest of public good since I occasionally notice people stumbling across this repo, I've since refactored it so it's a least not quite so bad as it was when originally implimented, however the code is still pretty terrible.
Poetry is a pretty great dependency management and packaging tool, I use it. If you want to use this for some reason, I suggest checking it out. Once you have it up just run poetry dev and it'll be setup and ready.
The package has an incredibly basic CLI, that will be accessable once you've installed the package. It is called crypto.
Run crypto --help for usage instructions.
