ancient codes

Ancient codes are early systems of writing used to send secret messages or organize laws. Examples include ciphers that substitute letters to hide meaning, like the Caesar cipher shifting alphabet letters, and legal codes such as the Code of Hammurabi, which listed rules and punishments. These codes helped authorities communicate securely, record laws, and protect sensitive information. They laid the groundwork for modern encryption and legal systems, demonstrating early efforts to ensure confidentiality and order across civilizations.
