  Schneier himself semi-regrets this one I believe as it teaches enough to be dangerous but not enough to understand the risks you are creating. Implementing ciphers is one thing, knitting them together into a secure protocol is something very different and very challenging.

  NO! Applied Crypto is at times a fascinating book, but it is terrible for a developer that wants to learn the fundamentals of crypto and how to avoid the most common mistakes people make. Its also really old at this point. A much better book is Schneier, Ferguson and Kohno's "Cryptography Engineering"[1]. It covers what makes for strong crypto primitives and why weaker ones are considered broken. Note that is book is starting to get a bit out dated (I don't remember it covering ECC at all, for example), but I don't know of any better book. I also endorse the Matasano Crypto challenges and the Coursera Crypto class taught by Dan Boneh as excellent learning resources.

  I'd recommend Cryptography Engineering over Applied Cryptography for programmers today. It has a lot of actionable info and is quite up to date. https://www.schneier.com/book-ce.html https://www.schneier.com/book-ce.html
