A good read

This is an interesting and surprisingly easy read, giving the reader a history of cryptography and predicting the next steps. It also includes tidbits on some of the interesting characters that played pivotal roles in the field.

Great Book, Great Read

Singh is entertaining and VERY knowledgeable on Crypto. He reviews all of the major cryptographic techniques, and gives a history of the subject that is pretty in depth. All in all, a terrific and educational read.

Rich history and nice technology review

Singh has done a wonderful job of making a dry subject fascinating. The history is amazing and well written. The technology of code making and code braking is quite complete, and could not be made more interesting of read. The end of the book may get too technical for the non-technical reader, but even they will be more than pleased with the first 3/4 of the book. The nature of the subject forces recent history to be left uncovered, but you will be amazed at what has recently become known from fifty years ago.
