Hi everybody,

My question concerns the expression Imagining plaintext 'kotz' :
Does it mean instead of encrypting 'kotz', 'kotk' is XORed with the key???

I haven't solved this one yet, but I think it means that the bytes i to i+3 should be xored with k (which is also 4 bytes long).

PS: Do you really think that this challenge is kotze?

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...
