Hello everyone!

So i made a coding and decoding machine 'cause i like to make things like this. So i tought ill' share it here maybe someone is interested in these kind of things.
Also if you have a code idea just tell me maybe i can make a "machine" out of it. so i don't know maybe you could use this somewhere to cheat or something. Actually i have a code which is based on the periodic table so you could easily use it on a chemistry exam or something.
The download link is here. (It's macro free)
If you want to know how it works just ask me and ill' try to explain it.
