Pro tip: if you encrypt your message with ROT13 twice, the security is also doubled

Last year, one of our assignments for school was to implement a caesar cipher in Java. There is that one guy, that doesn't understand the concept of dynamic variables, so he HARDCODED every single possibility for every character. More than 1000 lines for something this simple. Yes, we are studying informatics. Yes, he passed last year

Just in case anyone wonder how Erlang looks like.... Well here's a Caesar cipher programme.

University assignment asks to create some encryption harder to break than Caesar Cypher. So I decided to go online and look for some tips on making a somewhat decent algorithm.

Universal answer: don't do it

😶

Well then, night off I guess 😎

What did Caesar say when he lost a game of battleships?
“E-2, Brute?”

That dude that doesn't really understand the concept of cariables and hardcodes a caesar encryption/decryption.

I have no words for this. 1000+ lines of code
