SIGABA, also known as the EC-100 machine, was a cipher machine used by the United States during World War II for secure communications. Developed in the 1930s, SIGABA is notable for its complexity and security features, making it one of the most secure cipher machines of its time. The machine used a combination of rotating gears and electrical components to encrypt and decrypt messages. Its design allowed it to produce a vast number of possible settings, significantly complicating efforts to break its codes.
