The Caesar-Cracker is a program we developed in a computer science lesson at school. It is able to crack any message that was decrypted with the Caesar-cypher.
The Caesar-Cracker will generate 26 versions of the encrypted message (each version is decrypted by shifting the letters by n positions in one direction).
After that, it compares each word of each version with an English dictionary. If any decrypted word is a valid English word, the whole version is considered to possibly be the correct decryption and is outputted to the console.
It also allows you to encrypt a message to get an example.
