Same for me here, I’d like to be able to see validators 1 and 2 to understand what I’m doing the wrong way! An Enigma machine allows for billions and billions of ways to encode a message, making it incredibly difficult for other nations to crack German codes during the war — for a time the code seemed unbreakable. During World War II, the Germans were using an encryption code called Enigma – which was basically an encryption machine that encrypted messages for transmission. Source. This is a work in progress that will turn into a final article by the end of the semester in December of 2011. It’s fixed (and I’ve answered somewhere else). The Enigma machine works by swapping letters; it therefore has no separate mechanism for decryption, nor does it need one. My test case for the decoding is the following : Same issue here, for me I always fail validators 4 and 6, it’s probably something very stupid , but i can’t find it. CodinGame-Solutions. just beware of borders (values < or > to the 26 chars when converting) What are differences between validator test and ide test ? The reverse process is called decryption. Symmetric-key encryption are algorithms which use the same cryptographic keys for both encryption of plaintext and decryption of ciphertext. It is therefore unsurprising that when mechanical encryption machines (rotor machines) were invented in the wake of World War I to protect sensitive diplomatic, strategic and commercial information the encryption machines were known as Enigma … The most powerful of our Enigma Series of Encoders.
