Awesome read, interesting history behind some historical events. No prior knowledge of cryptography is needed to understand the material. Would recommend to buy.

Very readable by pretty much anybody. You either like puzzles or you don't. If you do, you will enjoy the insights into methodology presented here. After the first chapter it's possible to read it non-sequentially.

Read this book years ago, but lent it to a friend... time to read it again.

This book is well written, and given the subject, very entertaining with 'real-world' explanations of applied cryptography.

A good primer on the principles of encryption.

This book explains the history of cryptography clearly. It also explains how ciphers work and the difference between codes and ciphers. I have developed an interest in cryptography after the surveillance scandal,last year. This book made me even more interested in cryptography and now I have been looking for different books on cryptography. This book really opened my eyes about this subject and I hope I can contribute to the field. The only thing I didn't like about the book was the last chapter on quantum computers and quantum cryptography. Those fields are very interesting but my current capabilities limit my understanding making the reading of the chapter for me tedious. I liked appendices that delve deeper into certain forms of cryptography. I also like the further readings section and the cryptography puzzles, they are very helpful. I would recommend this book to anyone who want to know about cryptography and its impact on today's society(even though the book was written 15 years ago).

What I expected to be a dry book on science and mathematics turned into a gripping story of creative successes and dismal failures.

They say "truth is weirder than fiction", but in this case, it's also more entertaining.

This book gives a good history lesson in Codes, and how they were developed. It is written in such a way that its easy to follow and to understand. I would recommend it for anyone with a interest in codes and cryptology.

This was a great read as it simply laid out the history of code making and breaking. If you have any interest in the subject, this is a great place to start.

Ever wondered how information is kept secret through encryption? Start simple, wrap a cloth around a pole and write on the cloth! That was one of the early examples of encryption provided in the book. It takes you from there through increasingly sophisticated processes for encrypting information including what is used on computers.
