Cracking the Code

Humans have been keeping secrets for generations and using cryptology to make sure those secrets don’t fall into the wrong hands.

From the development of ancient Greek ciphers, to the creation of the Enigma and today's CRISPR technology, codes and codebreakers have changed the course of history. Today cryptology addresses cybersecurity and the ethics of hacking our own genetic code.

Cracking the Code reveals the history of codes, explores why humans keep secrets and introduces us to coding heroes like the Navajo Code Talkers from World War II. Codes have defined human history and will map our digital future. Will you be the next codebreaker to unlock the mysteries behind the codes that shape our world?
