Use the Caesar cipher with shift of 5 to encrypt the message: "See You Soon". Make blocks of size 3. A. XJJ DTZ XTTS B. XJJ DTZ XTT AAA C. XJJ DTZ XTT SEE D. XJJ DTZ XTT

To encrypt the message "See You Soon" using a Caesar cipher with a shift of 5, each letter is shifted five places down the alphabet. The encrypted characters become: - S → X - e → j - e → j - (space remains space) - Y → D - o → t - u → z - (space remains space) - S → X - o → t - o → t - n → s Putting it all together, we get "XJJ DTZ XTT". Now, let's form blocks of size 3: "XJJ DTZ XTT". So, the correct answer is D: XJJ DTZ XTT. Now for some extra fun! Historical Background: The Caesar cipher was named after Julius Caesar, who is said to have used it to protect his military messages. Imagine a time when communication was more secretive, and the most advanced technology was just a clever letter shift! It’s like the early version of texting in code! Real-World Application: To this day, Caesar ciphers are often used in puzzles and games as an introduction to cryptography. They might even pop up in escape room challenges where decoding messages can lead to the next clue. It’s a fun way to exercise both logic and creativity!
