This course is a friendly introduction to cryptology—the science of making and breaking secret messages. You’ll discover how classic ciphers (like Caesar shifts) evolved into modern encryption, learn the difference between cryptography (hiding information) and cryptanalysis (trying to uncover it), and see how codes and ciphers protect things like passwords, messages, and online payments. Through simple examples, short challenges, and “code-breaking” activities, you’ll build an intuitive understanding of how cryptology works and why it’s so important in today’s digital world.
