Kryptos - The Cipher (Part 4) - Correctly positioned decryption of the word BERLIN

EASTNORTHEAST - This is not exactly the hint Jim Sanborn (JS) gave for K4 on the 29th of January this year. He only gave NORTHEAST - which refers to the positions 26-34 of K4's plaintext.  Beside BERLIN and CLOCK it is the third revealed plaintext word of K4. However, also this hint does not seem to help much.  However, it just so happened, that a member in the yahoo kryptos group had a conversation with Jim Sanborn due to a submitted solution. Sandborn's answer to the question contained again the last clue which surprisingly was EASTNORTHEAST at position 22-34. Jim Sanborns compass rose at CIA There is disagreement if Jim revealed this on purpose or he did it accidentially, but the new extended clue seem to be serious and valid.Interestingly, EASTNORTHEAST is exactly the direction which is illustrated on the compass rose on one of the stones around kryptos, also created by Jim Sanborn. Actually, i dont really kn...

Kryptos - The Cipher (Part 1) - Introduction

Introduction. Since I think that KRYPTOS does not need any introduction, I will only give you a brief description of one of the most famous and only partially solved ciphers known today: KRYPTOS - Von Jim Sanborn - Jim Sanborn, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=8253447 KRYPTOS was constructed in Nov. 1990 on the ground of the CIA Headquarter in Langley, Virginia by Jim Sanborn It contains 4 ciphers (K1,K2,K3,K4) on its left side and some kind of Vigenère-Table on its right side K1, K2 and K3 were solved by James Gillogly in 1999. Afterwards, the CIA and later the NSA claimed that they had a solution to the first three ciphers at an earlier point in time Ed Scheidt, a cryptoanalyst and former director of the CIA, gave Sanborn the input of possible cryptographic techniques to use K1 is a variant of the Vigenère-Cipher (Quagmire 3) with the codewords KRYPTOS and PALIMPSES...

Kryptos - The Cipher (Part 2) - K4 abnormalities and solution attempts

This is Part 2 about Kryptos and the first post can be found here . In this post i will focus more on abnormalities and solutions attempts. Kryptos' Abnormalities Drawn by author. One noticeable fact is, that the letters KRYPTOS somehow are involved in the decryption process of all previous ciphers. In K1 and K2 they were directly used as one of the keywords in the Vigenère-Variant Quagmire3. For K3 there are several ways to transpose the ciphertext in order to reveal the plaintext, but one of them has to do with ordering/reordering the letters of KRYPTOS alphabetically. So, it seems plausible, that also in K4 these letters play a role in one or the other way. A further hint towards this is, that the letters of KRYPTOS all appear on the right side or in direct neighborhood on the left side, as marked below: 25| OB KR 26| UOXOGHULBSOLIFBBWFLRVQQPRNGKS SO 27| T WTQSJQSSEKZZWATJKLUDIAWINFBN YP 28| VTTMZF...
