Eons ago a friend and I started a mock company called MicroProgz. We barely knew anything about programming, but we were under the influence of the shareware trend and put out some really useless shareware applications. In particular, I was really excited about the concept of cryptography, albeit not to any mathematical extent, just to code silly algorithms that seemed to do a really good job if you wanted to manually decode the plain text.
XXX Filez 2K was our "flagship" application, and apparently our exuberant marketing actually fooled some people into thinking it did something useful, as we received a few requests about it.
