He invented it so if his messenger was robbed of that letter and the robber wouldn't be able to read it. It is probably one of the most simple codes ever. It is 3 letters back so A would be X.

Webb17 juni 2024 · 29. When trying to break an unknown cipher, one first needs to figure out what kind of cipher one it is. Generally, a good starting point would be to start with the most common and well known classical ciphers, eliminate those that obviously don't fit, and try the remaining ones to see if any of them might work.

WebbSo I have been thinking about a cipher possibility that includes a basic caesar cipher, but then the cipher text is scrambled. Eg Plain text: "This is some example text" Cipher text: "Wklv lv vrph hadpsoh whaw" Cipher text after scramble: "wl vvp apo hwkvl rhhdshwa" The same letters, and scrambled to a pattern only known to the sender/reciever. WebbI do have to admit, however, that if there's some simple shortcut to reliably determine the key length without (mostly) solving the cipher, I'm not aware of it. Edit: I did think of one shortcut: if the keylength were less than 6, the sixth letter of "earthquake", Q, would have to line up with one of the earlier letters of the same word, and thus follow it in the ciphertext.
