How do spies Pass on codes?

Answer 1

Spies pass on codes using a variety of methods, including secure digital communication, dead drops, and coded messages. They often employ encryption techniques to transform messages into unreadable formats, which can only be deciphered by the intended recipient. Additionally, they may use physical disguises or inconspicuous methods, such as embedding messages in everyday objects or using prearranged signals in conversation. These techniques help ensure the secrecy and security of the transmitted information.
