Cryptography made easy…er
Cryptography does not have to be mysterious — as author of Serious Cryptography Jean-Philippe Aumasson points out. It is meant to be fiendishly complex to break, and it remains very challenging to implement (see jokes on rolling your own crypto found all over the Net), but it is well within the grasp of most programmers to understand.
While many are intimidated by the prospect of digging into what is effectively a branch of number theory, the reality is that cryptography is squarely based in discrete mathematics—and good coders are all, without exception and often unknowingly, natural discrete math jugglers. If you are interested and you aced your data structures course, chances are that crypto will not be an unsurmountable challenge to you. Aumasson certainly seems to think so, and he walks us along his own path to the discovery of the cryptographic realm....
