Examines cryptography, discussing the history of the science, different cipher types, and how codes and codebreaking have changed with computers.
This work examines the logic and science behind various ciphers, their real world uses, how codes can be broken, and the use of technology in this oft-overlooked field.
While cracking a code might seem like something few of us would encounter in our daily lives, it is actually far more prevalent than we may realize. Anyone who has had personal information taken because of a hacked email account can understand the need for cryptography and the i…

"Double agents, code-cracking, and covert operations are not just the stuff of action movies or thrillers. Intelligence communities--comprised of spies as well as cryptographers and experts in a variety of other fields--have played significant roles in both past and present wars…
