Thoroughly enjoyed this book. Absolutely fascinating. I recommend this to any of my friends on the geeky end as it has lots of juicy technical bits. That said, don't be scared off by that as one could skim those bits and still really enjoy the historical aspects.

I was fascinated with codes and ciphers when I was a kid. I even had a "junior spy code kit" with a bunch of cool stuff and I could send little notes to friends with secret messages like "Mr. Nutzenjammer is a dork" and "Cindy eats her boogers" and we would all congratulate ourselves with our clever...

I first bought this book as a hardback, and now have an ebook. version too.It is a great read with easy to understand explanations of complicated issues such as Diffi-Helman key exchange without you having to be a maths genious.I find I dip into it frequently.

He also explains some interesting facts from contemporary history, e.g. concerning Ge...

I remember being very much at awe, reading about Fermat's Last Theorem (same author), but this book really didn't tell me anything new, except for some historical gossip on important figures in the history of cryptography. Probably, having a degree in mathematics and computer science doesn't help in...
