  <default-description>People love secrets. Ever since the first word was written, humans have sent coded messages to each other. In &lt;I&gt;The Code Book&lt;/I&gt;, Simon Singh, author of the bestselling &lt;I&gt;Fermat's Enigma&lt;/I&gt;, offers a peek into the world of cryptography and codes, from ancient texts through computer encryption. Singh's compelling history is woven through with stories of how codes and ciphers have played a vital role in warfare, politics, and royal intrigue. The major theme of &lt;I&gt;The Code Book&lt;/I&gt; is what Singh calls &quot;the ongoing evolutionary battle between codemakers and codebreakers,&quot; never more clear than in the chapters devoted to World War II. Cryptography came of age during that conflict, as secret communications became critical to both sides' success.&lt;p&gt;  &lt;blockquote&gt;Confronted with the prospect of defeat, the Allied cryptanalysts had worked night and day to penetrate German ciphers. It would appear that fear was the main driving force, and that adversity is one of the foundations of successful codebreaking.&lt;/blockquote&gt;&lt;p&gt;  In the information age, the fear that drives cryptographic improvements is both capitalistic and libertarian--corporations need encryption to ensure that their secrets don't fall into the hands of competitors and regulators, and ordinary people need encryption to keep their everyday communications private in a free society. Similarly, the battles for greater decryption power come from said competitors and governments wary of insurrection.&lt;p&gt;  &lt;I&gt;The Code Book&lt;/I&gt; is an excellent primer for those wishing to understand how the human need for privacy has manifested itself through cryptography.  Singh's accessible style and clear explanations of complex algorithms cut through the arcane mathematical details without oversimplifying.  &lt;I&gt;--Therese Littleton&lt;/I&gt; </default-description>

    <body><![CDATA[This book was fascinating, and the author did an incredible job of simplifying technical details so that they made sense. There were all sorts of cool stories from history. I would have actually enjoyed European history if they had told us stories like the one in this book about Mary, Queen of Scots...<a href="http://www.goodreads.com/review/show/53840692">more...</a>]]></body>

    <body><![CDATA[A history of cryptography from ancient Egypt through quantum computing.  My favorite parts were about WWII, with Turing and the Navajo Codetalkers.  Some parts were a touch slow - cryptography isn't nearly as thrilling as the activities associated with it - but by and large it was an informative rea...<a href="http://www.goodreads.com/review/show/70698943">more...</a>]]></body>

    <body><![CDATA[A review from someone who is not a mathematician, physicist, computer analyst nor an engineer. In fact, some of this material was visually familiar from the most agonizing and boring Cub scout field trip of my den-mom career, when we visited the National Cryptological Museum in MD.

    <body><![CDATA[A very informative book on history and how codes have been used, created, and broken time and time again. I would not have wanted to be royalty. Wow, what treachery and deceit. I found the part about Mary, Queen of Scots very unsettling]]></body>

    <body><![CDATA[The first book I've read by Simon Singh, I was interested in it because of my geeky computer science background. It's hard to get a degree in that without running into a few characters from this history of encryption, code breaking, and spies. It is fun to see how we've gone from replacing letters i...<a href="http://www.goodreads.com/review/show/2716037">more...</a>]]></body>
