Review of Simon Singh's The Code Book

Simon Singh’s The Code Book is a really good read. In it he goes through some really pivotal points in the history of Cryptography. He traces the evolution of codes from primitive Cesar cipher and substitution ciphers to quantum cryptography. There is a lot of good stuff in here, and there are times when you have to really pay attention, but it is certainly rewarding. If you ever wondered what PGP was, or RSA encryption, or you just wanted to know what that little lock that appears on your web browser when you are checking you bank statement is, or even Alan Turing’s role in WWII, you should read the book.
