Where do I learn about cryptography?

View on HN

(if this isn't a joke?) you might enjoy doing these http://www.matasano.com/articles/crypto-challenges/

Here is a free Udacity course on cryptography: https://www.udacity.com/course/cs387

The Matasano challenges are a good practical starting point to jump right in.

Coursera also has three cryptography classes: Cryptography I, Cryptography II, and Intro to Cryptography (all taught by Dan Boneh).

And, of course, Bruce Schneier's Cryptography Engineering (Applied Engineering is somewhat deprecated).

I can recommend "Applied Cryptography" by Bruce Schneier

Not even Bruce Schneier recommends Applied Cryptography. http://www.schneier.com/blog/archives/2009/09/the_cult_of_sc...

TLDR; Get "Cryptography Engineering"[0] instead.

"Practical Cryptography", by Bruce Schneier and Niels Ferguson, is meant to atone for the unfortunate real-world consequences of Applied Cryptography. It is comprehensive and good for people with basic discrete mathematics understanding.

Short story: Applied Cryptography is an old book and doesn't focus on end-user practicality. (I'd still recommend it for anyone looking to get deeply into cryptography, but it's not a good starting point.)

For the record, Cryptography Engineering is his latest book on the topic, and it is a good one. But like all technical books, it's also a little out of date.
