really liked it

A history of cryptography ought to have spy stories and treasure hunts and daring wartime conspiracies, which Simon Singh provides, but he grounds it all in strikingly clear mathematical and logical explanations of cryptographic methods. He tells the history as a back and forth between cryptographers and cryptanalysts, with one group having the upper hand at different points in history. With the very early ciphers, I already had a background intuition about how they might be deciphered, but by the third chapter I was experiencing amazement along with cryptographers of various centuries as different ciphers were unraveled. One of the best nonfiction I've read lately.
