About this video

🎬 Before end-to-end encryption and crypto wallets, there was… the Caesar Cipher! 👉 Over 2,000 years ago, Julius Caesar used this simple algorithm to hide messages by shifting letters in the alphabet. For example, “HELLO” becomes “KHOOR” if you shift each letter by 3. It may seem basic today, but it was revolutionary—and it laid the foundation for the encryption we now use to protect everything from WhatsApp chats to online banking. 💻🔒 #techhistory #encryption #CaesarCipher #cybersecurity #shorts
