Will one more clue unlock the last? For example, suppose that the plaintext to be encrypted is: The person sending the message chooses a passphrase and repeats it until it matches the length of the plaintext, for example, the passphrase “LEMON”: The ‘Keyed’ Vigenère Cipher uses an alternate tableau. The code remained unsolved. The Index of Coincidence [IC] measures the probability that any two randomly chosen source-language letters are the same. And indeed, with a bit of additional work, you will come to the conclusion that the 37 characters [5 + (8*4)] before the question mark. Every part of Kryptos has meaning, whether obvious or not. There is still a fourth section at the bottom consisting of 97 characters which remains uncracked.

Clearly, the passphrase characters for the first, second, and third column correspond to the letters: S, S and A. K  R  Y  P  T  O  S  A B C D E F G H I J L M N Q U V W X Z, S  A B C D E F G H I J L M N Q U V W X Z K  R  Y  P  T  O, A B C D E F G H I J L M N Q U V W X Z K  R  Y  P  T  O  S. At this point, it seems very likely that we are on the right path. In 2010, Sanborn released the first clue for solving these 97 letters.

In 2014 he revealed the word CLOCK in the next five, 70 through 74. Over the last 30 years, the fourth Kryptos code has been tackled by cryptography experts from the CIA, NSA as well as freelancers around the world. The first, which was released in … It remains unsolved. Next word is 'AUDIO' (if you would use secondary code 85122) and yes :) you need human to solve it (secondary code) - computer itself cannot do it. ( Log Out /  But after nearly three decades, one brief passage remains uncracked. I know that ALL letters in a given column have been encrypted with the same “Vigenère alphabet”. Tiny steps for tiny feet… Stay tuned!

The right-hand side of the sculpture comprises a keyed Vigenère encryption tableau, consisting of 867 letters. A graphic with an earlier version of this article showed an incorrect decryption for the end of Passage Two. The “Alphabet Key” helps decide the alphabet to use to encrypt and decrypt the message. We will decode this too in a following post. ONLY WW.” The “W.W." Code detectives worked to crack the puzzle following the Berlin revelation.
