“And having thus chosen our course, without guile, and with pure purpose, let us renew our trust in God, and go forward without fear, and with manly hearts.”

Abraham Lincoln — Address to congress (July 4th, 1861)

Kryptos is a sculpture by the American artist Jim Sanborn located on the grounds of the Central Intelligence Agency (CIA) in Langley, Virginia. Of the four parts of the message, the first three have been solved. The last part of the message remains as one of the most famous unsolved code in the world.

The ciphertext on the left-hand side of the sculpture (as seen from the courtyard) of the main sculpture contains 869 characters in total (865 letters and 4 question marks). The right-hand side of the sculpture comprises a keyed Vigenère encryption tableau, consisting of 867 letters. In our last post about KRYPTOS, we learned how to break a Vigenère code. In this post, we finish the job regarding the entire section II. Follow us on Twitter: @INTEL_TODAY Continue reading →

“I genuinely enjoyed working on the Kryptos ciphers. Professional cryptographers almost certainly could have broken these codes much faster, and would have used superior methods. But I doubt that they would have derived as much satisfaction as I have. I didn’t use any computers to decrypt the Kryptos codes–just pencil and paper, some common sense, and a lot of perseverance. Using a computer would have cheated me out of the feeling of accomplishment that I obtained, because I have found that often in life the journey itself can be more gratifying than arriving at the final destination. Mountains are not climbed nor marathons run merely to reach a geographical location–there are much easier ways to accomplish these feats–but as personal and spiritual challenges to the participants.

When confronted with a puzzle or problem, we sometimes can lose sight of the fact that we have issued a challenge to ourselves–not to our tools. And before we automatically reach for our computers, we sometimes need to remember that we already possess the most essential and powerful problem solving tool within our own minds.”
