Cipher attack

WebSep 4, 2024 · The actual attack angle lies in the repetition of the key. If you correctly guess the key length you can just treat it as a Caesar cipher. There are a possibility of 26 n keys, where n is the key length. I.e. if the known key length is 4 there would be a total of 26 4 = 456976 possible keys.
