I wrote this towards the end of fall semester for one of my classes, but I figured it was decent enough to share. I'm looking through some of my other papers, and I dunno, maybe I'll release those as well, but their more opinionated or biased than I like. Anyways, this is meant to help serve as a first step into cryptographic security, and I think that being introduced to an obsolete yet easy to comprehend cipher is a good way of doing that.
It's in PDF format, just a heads up:
