We have all heard about the famous Enigma code and how important it was for the Allied effort during World War II when it was finally broken. It was the same thing with the Ancient Egyptians and the Rosetta stone that allowed researchers to decipher the ancient languages and codes written by mathematicians thousands of years ago. This being said, there are many other famous ciphers, codes, and writing systems that remain unsolved to this day. Over the next few minutes, we will learn what are the ten biggest uncracked codes and ciphers in history.
Designed by American artist James Sanborn, Kryptos is a sculpture located on the grounds of the Central Intelligence Agency in Langley, Virginia. Since it was erected in 1990, there have been many attempts to break the encrypted message displayed on the sculpture, all failing to figure out what the 859 characters are supposed to mean. Although the CIA and other cryptanalysts have attempted to decipher the message, neither have managed to solve the meaning of more than 768 characters out of the total 869.
