Why did I love this book?
Rarely can a book intertwine the inner workings, history, and applications of something--particularly when that something is a complicated topic like cryptography. But Simon Singh pulls it off with style. The Code Book delves into the history of ciphers, how they have been used, and how they have impacted history, from the 1500s through today. It also explains how these ciphers actually work, using language and illustrations that do not require a PhD in mathematics to understand. You will come away with a greater understanding and appreciation for how cryptography makes us more secure.
