Hey Google!: "Serious Cryptography - A Practical Introduction to Modern Encryption" by Jean-Philippe Aumasson

Google does not really need to crack encryption!

If you are using a Google search engine or a Chrome Browser, the information may not be tagged to you individually, but the global use is factored in for you within some narrow range of locales and your averaged usage of sites and buying patterns are known sufficient to the purpose

Philosopher Alfred North Whitehead noted that modern philosophy is simply a series of footnotes to Plato. When it comes to cryptography, much of it is simply footnotes to Bruce Schneier’s classic work Applied Cryptography: Protocols, Algorithms and Source Code in C.

In Serious Cryptography: A Practical Introduction to Modern Encryption, Jean-Philippe Aumasson has written not just some good footnotes to Schneier, but a valuable work on modern encryption and cryptography. A lot has changed since Ap

As a cloud services software engineer this book gave me a good overview of all the common encryption and authentication protocols I interact with day to day. I now feel like I know enough to talk somewhat intelligently with the the security engineers at my company and hopefully notice the warning signs when some out-dated or insecure protocol is being used. Sometimes I got bogged down in the math and details of the protocols but I just skimmed when I was overwhelmed to get the gist. At least I k ...more
Interesting book but exhausting. This has been a work book group discussion book. And frankly it really didn't lend itself to discussion - though it did inspire some discussion. Basically this is a fairly hard subject not made especially easier by this book. But some chapters were better than others. And if I were doing cryptography as a more primary part of my job it would have been more useful. The quantum chapter did a pretty good job of explaining the problem and work arounds, and problems w ...more

For an ordinary software developer, I think this was a great overview to get you situated on the cryptography landscape. The order that he built up the topics was great, and practical advice such as the "how things can go wrong" sections gave very useful perspectives.

However, cryptography is a subject with a lot of detail, and at times, I think a bit too much was packed into too short of a book. For example, the introductory chapter covered subjects like malleability and attack models too briskl

I think should have actually been called Coincise Cryptography. It is difficult to understand without prior knowledge, and of the topic I did not know something beforehand, I can not say I know more now. It's just too quick. Also, technical explanations are many, which is good, but again too short and with no examples for most part. ...more
Every chapter has the same structure : the subject is introduced, explained. Then the author concludes by the proper ways of implementing the theoretical algorithms, the possible attacks and two sections titled "how things can go wrong" and "further reading".

Chapter 1 introduces vocabulary and illustrates with two historical basis encryption schemes : Ceasar's cipher and Vigenère's cipher. I disagree with the way the cryptanalysis of Vigenère's cipher is presented, because it omits the fact that

Great introduction to the most important ideas in contemporary cryptography. The author has a deep knowledge of the subject matter and clearly communicates the crux of the most critical issues.
The book is written for programmers, there are some basic mathematics and algorithms used to illustrate the main ideas. But, descriptions do not directly depend on the experience or knowledge of the reader. It is not a textbook.
Topics have been well chosen, keeping the book a reasonable size but covering t

For what was supposed to be a "practical" introduction, the book turned out to be pretty tedious, not that much in terms of mathematical concepts but in the way of writing. It IS an overview - an extensive look on a number of areas crucial to the topic, but also quite a detailed one. In fact, while (of course) I considered it much easier to read than most academic books on cryptography, I felt like it was too in-depth at times (where details could have been omitted by a simple ref). On the other ...more

I really enjoyed this book : I believe "Serious Cryptography" is the introductory cryptography book for the 2020s - with its clear, logical organization, insightful examples, and coverage of the latest trends and standards; Aumasson's book does a great job of conveying basic and intermediate concepts of its challenging subject.

Most people interested in cryptography had started their journeys by reading Bruce Schneier's "Applied Cryptography". While still a great book, it has been a while since i

This is a fairly complete introduction to modern cryptography, and to the most commonly encountered cryptographic functions in today’s computer networking systems. The organization is primarily topical and loosely sequential. The presentation is supported in the form of logical operations and operational block diagrams, and with occasional code blocks; however, there are no expository examples. This style of presentation makes it a suitable textbook to support a set of lectures, but for fast sel ...more

Read as part of a book club at work. It didn't spark much in the way of discussion, but I feel like I'd have liked it less if I wasn't reading it as a group. I found the parts of the book focussing on how encryption can be attacked to be the most compelling, other parts felt like they either dove straight into deep math or lacked depth (and somehow, occasionally, both at the same time). Since we read it as a group it gave us some opportunities to seek out different explanations on the same topic ...more

As the title says, this book tries to explain modern encryption at an introductory level with a practical point of view. The catch, in my opinion, is that modern encryption is based on somewhat complicated math. This mean that you will see a lot "this is beyond the scope of this book". I ended up finding too swallow the chapters about things I already knew and too confusing the chapters about things new to me. The author sure knows about what he is talking about and the "what can go wrong" secti ...more

JP Aumasson's book is definitely the most modern and comprehensive survey of cryptography topics that I have read. While this book will by no means make you a cryptographer, it does provide a good starting point for understanding the most important topics in the subject as well as resources for diving deeper into each of the topics. Aumasson strikes a decent-ish balance between superficial descriptions of nuanced topics and letting the reader get mired in the technical details of the math. This ...more

This book is a great overview of cryptography. I was mostly glad for "how things can go wrong" sections at the end of each chapter. The only problem I had with this book is it tried to cover a lot of math details on a few pages. One page was "kindergarten" math, and on the other already mathematical constructs I didn't understand. I can recommend it for understanding key concepts of cryptography, but due to only few examples and not all complex problems explained in depth, don't expect you will ...more

The content was well chosen and most of the time, easy to read. But some topics were overcomplicated (like CRT) and the book contains a *huge* amount of typos.

Some of them are crucial for understanding the ciphers, so you need at least to consult the wiki, like I did. The mathematical formulas use occasionally inconsistent notation, often mistaking superscript with subscript, or n with N. If you haven't already read some cryptography textbook, I consider it too confusing to begin with. But othe

I have been unusually busy the last few months which means that I have not gotten my normal reading done, and that also means my reading of this book was very fractured. I ended up settling for more of an overview read. As the subtitle of the book reads, this is a practical book. It is heavy on the mechanics of Cryptography. I look at this as more of a reference book that I will go to when ever I have a question in the future. Although it is practical, it is written accessibly for must dedicated ...more

This book covers everything one should know about cryptography, both beginners and advanced practicioners. All concepts are properly explained, although for someone who hasn't practiced it even one day - a bit challenging. I have built concepts maps in order to memorize how it works and then practiced by using basic examples. After reading it (and using many other online sources) I must say I came to understand all the basics of cryptography and can successfuly judge myself whether an encryption ...more

This book really covers practical and modern cryptography in a short and readable manner.
Of course it could have included much more content or examples etc, but I think it's a unique book in cryptography field and I think it would be better if the reader has some high level knowledge about cryptography before reading this book, as it's not a beginner's book. I also like the fact that author skips advanced theoretical math to appear to non-academics and engineers

I really enjoyed this book. I already knew much of the foundations and everyday details but not much of the real maths or the attacker centric parts. The maths was a little heavy at times, even though it was mostly kept simple enough for any reader to grasp. This book is an excellent introduction into practical cryptography and I highly recommend it. Already bought myself the paperback edition to use as a reference.

Best Encryption/Crypto book ever. Simple, Easy to understand and with interesting facts.

Probably one of the crypto books on my shelf that has aged best.
The last chapter deals with quantum and goes well with Aaronson's book - or, as it turned out in my case, as light intro to it.

This book is the best introductory book for aspiring crypto-nerds. It answered all the questions I was too afraid to ask, like what is HMAC, what does CBC vs. CTR mean, how does TLS really work, and much more. It also has a concise easy to understand writing style that anyone without a cryptographic background can follow.

Definitely recommended for security folks who want to dip their toes a little deeper into the how these cryptographic primitives actually work.

This book is just an overview of modern cryptography. Doesn't go into too many details, but contains lots of information with enough details to give you a basic understanding of all the concepts of cryptography.
I would recommend reading "Understanding cryptography" by Christof Paar before reading this book.
