Codes & Ciphers

What is the difference between a code and a cipher? How did Caesar send secret messages? How do you beat frequency analysis? What is a side-channel attack? How does RSA end-to-end encryption actually work? 

In this fascinating little book, packed with numerous helpful illustrations and worked examples, polymath Steven Goodwin reveals the secrets of the codemakers, and the toolkits of the codebreakers. If you ever wanted to send a secret message to someone special, this book will show you how.

Steven Goodwin has been hooked on all things tech since he could barely reach a keyboard. He wrote his first lines of code at just eight years old and crafted his very first synthesizer while still a teenager. Since then, he’s worn many hats―developer, CTO, system architect―and worked with companies of all shapes and sizes, always pushing the boundaries of innovation. A true thought leader in the industry, he’s also a speaker and a mentor, helping others navigate the ever-evolving tech landscape. When he’s not geeking out over the latest tech trends, you’ll find him . . . well, still geeking out over tech. It’s kind of his thing.
