Title: Interesting book!
Review: Singh relates a plenty of interesting facts of the history of cryptography that were kept secret for a long time. Besides, a good introduction to the idea of some simple cryptographic schemes gives the reader a little bit of the thrill that involve the study of codes. Although I liked the book very much, in my opinion, the title does not reflect what's inside: actually, you don't lear how to make, break, hack or crack anything.
