To make their encryption harder to crack, a spy decides to use a sequence of 3 Caesar Shifts: first a \(+11\) Caesar Shift, then a \(+24\) Caesar Shift, then finally a \(+17\) Caesar Shift. How will the spy encode the letter X?
DRKYVDRKZTJ ZJ KYV HLVVE FW KYV JTZVETVJ, REU ELDSVI KYVFIP ZJ KYV HLVVE FW DRKYVDRKZTJ.
The message above was encoded using a Caesar Shift. The letter pair "KY" appears frequently in the encoded message. Which of these common letter pairs could the encoded letter pair "KY" represent?
Which of these Caesar Shifts encodes the letter A differently than the others?
