Negative Positive
Title: Absolutely fascinating read
Review: I work in the network security field, and this book has renewed my interest in what I do. Simon Singh has written a great narrative on the history of cryptography, and it was able to captivate my interest from start to end. I feel like I have a better understanding and appreciation for the security mechanisms we use day to day. I imagine this would also be a very good read for anyone doing a security certification (Security+, CCNA Security, CISSP) because it transforms a bunch of charts on a set of notes into a story that better explains the evolution of security.
Is the review positive or negative?
