  • サマリー

  • Have you ever used Morse Code, written a hidden message in a note to a friend, or even spoken pig latin to keep a secret from some young kids? No matter the method, we all have information that we’d like to keep private. Today banking, tech security, and even text messaging all involve encryption. Oftentimes computers are needed to “hack” into or break through these extra measures. But how was this done before computers? Join us as we take a breath of dead air with William and Elizebeth Friedman, who broke codes in the service of their country long before the digital age.
