Kryptos – The Coded Sculpture No One Has Been Able to Decipher for 30 Years

The CIA headquarters in Langley is home to lost of mysteries, but one in particular has captured the attention of professional code breakers and puzzle enthusiasts for the last three decades.

Kryptos, a coded sculpture created by American artist Jim Sanborn has remained unsolved ever since it was originally installed at the CIA headquarters in November of 1990. The agency’s code breakers as well as other professional puzzle solvers around the world have been struggling to unravel the secrets of the 1,800 characters carved into the 12-foot block of copper, and although they’ve succeeded in cracking three of the coded messages created by Sanborn, the fourth and final one remains unsolved. Experts have tried every technique in the book, transposition, binary, polyalphabetic substitution, even Morse code, but so far no one has been able to decipher the 97-character-long fourth part of the Kryptos Sculpture.

11-Year-Old Entrepreneur Sells Secure Account Passwords for $2 Each

11-year-old Mira Modi is cashing in on her knowledge of strong, easy-to-memorize passwords. She started her own online business earlier this month, selling hand-generated cryptographic passwords for $2 each!

“I’m a sixth-grade student in New York City,” Mira writes on her website. “This is my first business (other than occasional lemonade stands!). But I’m very excited about it and will be very responsible.” She also explains how Diceware, a decades-old password generating system, works: “You roll a die 5 times and write down each number. Then you look up the resulting five-digit number in the Diceware dictionary, which contains a numbered list of short words.”

The result, apparently, is a combination of five to eight words in a non-sensical string that is so random that it’s extremely difficult to crack. While a five-word string is breakable with “a thousand or so PCs equipped with high-end graphics processors,” an eight-word string “should be completely secure through 2050.”
