The book begins with a chapter that introduces the subject of cryptography to the reader. The second chapter discusses how to implement large integer arithmetic as required by RSA and ECC public key algorithms The subsequent chapters discuss the implementation of symmetric ciphers, one-way hashes, message authentication codes, combined authentication and encryption modes, public key cryptography and finally portable coding practices. Each chapter includes in-depth discussion on memory/size/speed performance trade-offs as well as what cryptographic problems are solved with the specific topics at hand.

Free Cryptography for Developers
A lot of people who have read "Applied Cryptography" by BRuce Schneier are themselves not cryptographers or developing cryptographic software. In fact, very few people actually develop cryptographic software because it's tough to get right and most crypto libraries provide everything you need. However, for those that wish to enter the field, it can be daunting to learn. If you'd like to be one of those few, Tom St Denis' "Cryptography for Developers" may be for you.
The book's writing is clear and focused, not surprising given that the author has written before. St Denis makes a good choice to focus on new material for this book, specifically pointing you at other books for a background in cryptography and "bignum" math (very, very large numbers, which require atypical methods to manipulate).
If you're a C code developer, you'll get the material very well. If you're C isn't very strong, or you need the code for another language, you'll probably have some difficulty in making use of it (depending on how skilled you are with C). However, the code is clear and well annotated, so you can make pretty good sense of it pretty quickly.
Chapter 2 starts off with a bang and covers ASN.1 encoding. This is not a very common topic, so this is one of the only places you may find this sort of thing covered well. Right away you can see what you're in for: very clear background info, good use of illustrations, well written code with lots of annotations, and very sharp focus.
Chapter 3 covers random numbers (specifically RNGs and PRNGs). While you'll want to complement this with something like the CRC Applied Crypto chapters on random numbers, you'll get a pretty good idea of how to gather and make use of random numbers.
I picked up this book with the hopes of being able to understand the algorithms behind commonly used cryptography. Sadly this book alone is *not* enough, you will need other sources if you plan to understand the details.
WHAT THIS BOOK DOES CORRECTLY
- Gives very decent explanations of the concepts at a high level (and semi low level)
- Uses lots of "why would you want/need to do this" type of examples
WHAT THIS BOOK FAILS AT
- You will *see* source code snippets throughout the text. But alas they are just that. Why not provide complete code!?!?! Luckily you can download other peoples source code but it won't *sync up* with the snippets of the authors or align with his explanations.
- At first glance it *seems* like all the info is given, but it is not. Example, for the RSA key generation in Ch.9, he explains how to generate the public modulus, private exponent and so on, but *not* how to generate the public exponent. How completely USELESS IS THAT? It's like giving somebody a car without wheels. Again,you can find this by searching the web (but you shouldn't have to)
So it is a strange book to read in that *it seems* like it's leading you down the correct hallway, only to find the door locked at the end. For a book on cryptography (secrets/encryption) it's ironic that some important and basic information is left out.
So this book is a pretty good start, but it's not the final book you will buy (but it could have been).
What this book needs to do to be better is simple
** List complete source code at the end of the book (or online) that syncs up with the chapters explanations, in the manner that there should be a single file called "md5.c" or "md5.pl" (i.e.
