Very readable but downgraded my rating because it is now unfortunately a bit out of date
Beautiful insight into cryptography throughout history (up until 1999.). Much more interesting than I anticipated.
The most beautiful part is foreshadowing bitcoin, which today stands strong on the grounds of breakthrough concepts explained throughout the second half of the book.
About the history of encryption, with sometimes quite technical explanations offset by some memorable stories, like how the US used Navajos to communicate on the battlefield, in lieu of an unbreakable code.
