SIGABA

SIGABA was a highly secure encryption machine used by the U.S. during World War II to protect military communications. It employed complex electronic and mechanical systems to encode and decode messages, making it extremely difficult for enemies to intercept or decipher the information. Unlike simpler ciphers, SIGABA used multiple rotating cipher wheels and secret settings, creating a vast number of possible codes. This made it one of the most secure cipher machines of its time, ensuring the confidentiality of important military operations. Its reliability and security helped the Allies maintain strategic advantages during the war.
