Ok, this makes imo more sense, too, because i think,otherwise the legitimate 'receiver' wouldn't be able to reconstruct the original plaintext by only owning k and x...

no of course this challenge is no 'kotze' ;) no better word came to my mind...

Didactic Feedback Cipher Long 2

Hi everybody,

My question concerns the expression

Code: Select all

c = (txt[i] -> txt[i + 3]) ^ k
Imagining plaintext 'kotz' :
Does it mean instead of encrypting 'kotz', 'kotk' is XORed with the key???
