How are codes and ciphers used in spycraft?

Codes and ciphers have always been crucial tools in the world of spycraft. They are used to ensure the secure transmission of confidential information between spies and their handlers, as well as to protect sensitive communications from interception by adversaries. Codes involve substituting words, phrases, or even individual letters with other symbols, whereas ciphers involve rearranging or scrambling the letters in a message to make it unreadable without the proper key. By utilizing these techniques, spies can create secret, encrypted messages that are virtually impossible to decipher without the correct knowledge or algorithm. This allows them to safely relay important intelligence, coordinate covert operations, and maintain anonymity in the high-stakes world of espionage.
