Kryptos- The codes that even CIA could not break

Kryptos

      Outside the headquarters of CIA in Langley, Va, there is a mysterious encrypted sculpture. It was designed by artist Jim Sanborn. The script is so mysterious that even the CIA has not been able to crack it completely. The sculpture is in total a collection of four inscriptions. Though the first three inscriptions have been cracked, fourth one isn still unknown. No one till the day knows what the fourth inscription means. In 2006, Sanborn gave a small clue that there is clues in the first inscription to the last one. But till this day, the fourth one remains unsolved. This is the reason why this inscription is one of the mysteries.
