Didactic Feedback Cipher Long 2
Hi everybody,
My question concerns the expression
Imagining plaintext 'kotz' :
Does it mean instead of encrypting 'kotz', 'kotk' is XORed with the key???
My question concerns the expression
Code: Select all
c = (txt[i] -> txt[i + 3]) ^ k
Does it mean instead of encrypting 'kotz', 'kotk' is XORed with the key???
