Jim Sanborn, creator of the famous Kryptos sculpture, has published a third clue: the word NORTHEAST appears in the plaintext of the unsolved message part.

As most readers of this blog will know, Kryptos is a sculpture located at the entrance of the CIA headquarters in Langley, Virginia. It was created by local artist Jim Sanborn in 1990. Kryptos bears an encrypted inscription, which has become the most famous crypto puzzle of the last four decades. The sculpture is not accessible to the public.

Kryptos

As it turned out, the ciphertext on Kryptos consists of four parts encrypted in different ways. Part 1 is encrypted in a polyalphabetic cipher with the keyword PALIMPSEST, part 2 in the same way with ABSCISSA. In both cases the alphabet is used in a permuted way with the letters K, R, Y, P, T, O, and S standing at the beginning. The third part 3 of the encrypted Kryptos inscription was made with a transposition cipher.

Parts 1-3 of Kryptos were solved three times independently from each other. They were first broken in 1992 by a team of NSA cryptologists, including Ken Miller and Dennis McDaniels. Six years later, CIA employee David Stein found the three solutions, as well. As both the NSA and the CIA kept their codebreaking successes secret, the Kryptos encryption was still considered unsolved in the public, when in 1999 Jim Gillogly, a reader of this blog, found the solution of the three cryptograms and became celebrated as the first one to break them. Only later, the NSA’s and David Stein’s work were unclassified and published.

Part 4 (also known as K4) is still a mystery. Neither the cipher used nor the plaintext are known. K4 reads as follows:

                           OBKR
UOXOGHULBSOLIFBBWFLRVQQPRNGKSSO
TWTQSJQSSEKZZWATJKLUDIAWINFBNYP
VTTMZFPKWGDKZXTJCDIGKUHUAUEKCAR

Over the years, the Kryptos inscription has become one of the most famous encrypted messages in the world and the world’s most renowned crypto puzzle. And thanks to the inscription, the Kryptos sculpture has become one of the most popular works of modern art – even if this popularity is mainly due to puzzle lovers and not to art lovers.

The fourth Kryptos part is included in almost every list of famous unsolved cryptograms I am aware of, including my top 50 unsolved cryptograms list. It is There are chapters about K4 in my book Nicht zu knacken and in Craig Bauer’s Unsolved!. In addition, I wrote an article about Kryptos and K4 for the online edition of the German magazine Focus.

The community of Kryptos enthusiasts is headed by Elonka Dunin. Check here for her Kryptos web page. Although Elonka has gathered a considerable number of skilled codebreakers around her, all their efforts to break K4 have proven unseccessful to date.

Jim Sanborn has always resisted the temptation to make a few quick dollars by creating additional encrypted artworks. One of the few exceptions is the Sanborn sculpture Cyrillic Projector, whose encrypted inscription has long been solved.

 

Sanborn’s hints

In 2010 Jim Sanborn offered a hint, which was first published in the New York Times. He revealed that the 64th through 69th positions of the fourth Kryptos part decrypt to the word BERLIN.

Four years later, Sanborn stated that the word CLOCK follows BERLIN in the plaintext. Again, this information was published in the New York Times. Codebreakers in all the world tried to decipher the fourth Kryptos part with the two clues, but to no avail.

For the year 2019, Sanborn announced to publish another clue. Much to the disappointment of many crypto-mystery fans, this didn’t happen. However, yesterday an article giving another hint finally appeared in the New York Times (thanks to Lance Estes and Michael Hörenberg for informing me about it). In this article it says:

So now, Mr. Sanborn, at 74, is giving the world another shot: the word NORTHEAST, at positions 26 through 34.

This means that we now know three words that appear in the plaintext of the fourth Kryptos part. In the following diagram these expressions are displayed above their ciphertext counterparts:

                           OBKR

                     NORTHEAST
UOXOGHULBSOLIFBBWFLRVQQPRNGKSSO

                            BER

According to Sanborn, this third Kryptos clue is the last one. In addition, we can read the following in the New York Times article:

He [Sanborn] has decided that if the code is not broken when he dies, the secret will be put up for auction. He might even do it in his lifetime. “I do realize that the value of Kryptos is unknown and that perhaps this concept will bear little fruit,” he said. The buyer could reveal the secret or perpetuate the mystery and maintain the system for submissions.

So, if you want to know the solution of K4, you should either put some money aside for purchasing it, or you can try to figure it out based on the new clue. If you decide for the latter, you are welcome to share your thoughts in the comments section.

    I am living in Berlin since 1996, but there never was a Gatow airport but only an RAF airbase (until 1990, I think).

    @Ralf
    RAF station Gatow was built by the Luftwaffe and opened on April 1 1936.
    After the war the RAF took over the airbase and operated from it until the last flight June 30 1994.
    The motto of the RAF base Gatow was Pons Heri, Pons Hodi.which translates to a bridge yesterday, a bridge today.

    It was instrumenal in the Berlin Airlift.

    Airport

    They all fit.

    And its just a nice story, that is all.

    It has also has quite the significance with SIGINT, was a GCHQ main interception point for east bloc communications. Maybe also the airport of choice for spies. Maybe there is also some urgency in possible physical/geograhical components of the puzzle since Gatow is getting a makover and Tegel Airport is (maybe! finally.) shuttering down soon.

    That’s exactly why I don’t talk publicly about my work on KRYPTOS. It is all useless. Have you ever wondered why real crypto experts don’t participate in such speculations? They know that the algorithm has to be worked out first. The plaintext clues can then be used afterwards to check the result. Why has Sanborn never commented directly on the system used? Why has he never made a piece of plain text public that is at the beginning of the message? You should ask yourself such questions. Without the algorithms, Sanborn could have published 90 percent of the plaintext and it would still be impossible to decipher the rest. First work out the system used! It should be a workable (practical) system, that can be used from a spy in the field, not the Bible code. Jim Sanborn about clues to the sysem used: “They are in plain sight.” (CTV 2005). DYAHR ! Jim Sanborn: When showed the out-of-alignment letters, he said, “They’re important”. Sanborn asked Elonka if anything else had been figured out about them. (from Elonka Dunin’s 2003 roadtrip). Why am I not hearing anything about this in public speculations ??? I just always hear trash and world conspiracy theories.

    – “The other half will be encoded in a modern system for the project by an expert cryptographer…” Is it modern to throw letters back and forth?

    – Artists express themselves through their art. Jim Sanborn said that he would give a hint every 10 years. Ten Years after Kryptos, he did a series of binary art. First clue?

    – Why did he place the HYDRA Video (DYAHR) right above Kryptos on his website?

    – On the website of Jim Sanborn, the artwork Rippowam is listed as Kryptos related art. This work of art consists among other things of binary ASCII code.

    Ask such questions!

    I only looked Gatow up after Ralf mentioned that he never had heard of Gatow airbase.

    The article (in German language) did not mention any sigint only that Eisenhower met Clay on this airfield.

    To others I would like to repeat the polite words from Klaus :

    “or you can try to figure it out based on the new clue. If you decide for the latter, you are welcome to share your thoughts in the comments section.”

    OK. Let’s see how far we can get here without crap and trash. Why transposition? Mr. Sanborn stated a 1 to 1 relationship between NYPVTT and BERLIN. The index of coincidence of K4 is too low for a transposition only cipher, there must be a very good scramble on the top. AND: How did the receiver of the message got the key? Ed Scheidt said: “How do you deliver a message in such a way that it conveys not only the encrypted data, but also the key?” (from Elonka Dunin’s 2003 roadtrip). And how could Mr. Sanborn create the KRYPTOS pattern in the right part of message K4? Because he could choose OBKR arbitrarily. Afterwards! OBKR is also in “plain sight”. We have to work with what we have. Not with what we don’t have. If the actual plaintext does not begin with OBKR or even UOXO, this also makes sense: “SLOWLY DESPARATLY SLOWLY … [the] DEBRIS THAT ENCUMBERED THE LOWER PART … WAS REMOVED”. I have another very! good reason to assume that the message doesn’t start with OBKR, but I’m not going to say anything about that yet.

    Another statement from Mr. Sanborn: “It’s not necessary to have a particular book to solve K4, just “to be able to read””. (Notes from the CNN documentary meeting)

    Am I the “German Guesser”? I don’t know. By the way I don’t like this term.
    Am I German: Yes
    Did I sent a (partial) solution to Jim Sanborn in February 2018 (exactly 1 year before the CNN documentary meeting): Yes

    I suspect some of you do not know where the term “German Guesser” comes from. You have to know that if you pay your $ 50 and submit your solution, Jim Sanborn will only give you a YES or NO. Never a reaction in any way. From the famous KRYPTOS FEES PDF: “PLEASE NOTE: THAT JIM SANBORN WILL NOT INTENTIONALLY REVEAL CLUES OR A SOLUTION TO THE REMAINING UNSOLVED K4 SECTION.” So in my case: NO. The following happened during the CNN meeting in spring 2019: “When asked about the solutions that have been sent to him (Jim Sanborn), and whether any of them were close, Jim said he got one from Germany about a year ago that was “kind of scary”, that the first part had started to look right, but then the rest didn’t.”

    I’m honest, I want to breack the message as much as everyone else. So I will not be able to provide you with all the information. But because we have the year of the 30th anniversary and because it seems that the interest in KRYPTOS has decreased considerably due to a lack of progress and information, here is some new information. Maybe they are useful for someone. What is special, is certainly not the short piece of plain text, but at what position it is and why:

    2 step encryption. I number the steps from an encryption point of view.

    OBKR
    ^—– Key to encrypt/decrypt the message key for step 1 (Of course you need some additional information to make uses of it. An additional secret.)

    UOXO
    ^—– Key or Part of it for step 1 or start of the plaintext

    Among other things and shortend, this is what Mr. Sanborn saw:

    OBKRUOXOGHUL
    XXXXCIAX….
    OBKRUOXOGHUL
    XXXXCIAW….

    Depends on the 2 encryption steps. The X is just a placeholder to move the text to the fifth position.

    It is a common way to transmit the encrypted message key with the message and an information how to decrypt it. See the Germans procedures in WWII. By the way: K4 is not ENIGMA coded.

    Hope this helps

    @Marc: To decrypt the message key from UOXO (CIAX or CIAW) I didn’t need any transposition. Now I’m stuck. Depending on the method, I still get a little plain text afterwards, but then it breaks off. In my opinion, a classic transposition, in which letters were exchanged, was not used or must be undone at some point. But you are right, possibly an unusual type of transposition. DYAHR can be swapped to HYDRA. But that doesn’t necessarily mean that letters have to be swapped. Take a closer look at DYAHR and consider what this type of representation could represent… You may receive a clue from the Morse code.

    I am not a fan of the theories, that Jim Sanborn generated any keys from the ciphertext of the other messages. Nor do I believe that apart from DYAHR there are any other clues in the ciphertexts visible on the panel. It is virtually impossible to foresee or plan what the ciphertext look like after encryption. There is a newspaper clip in the FOIA documents in which Mr. Sanborn says: “Anyone who knows a coding system called the Vigenere Tableau, invented in 1586 by French diplomat Blaise de Vigenere, will be able to decipher one half of the phrase. The other half will be encoded in a modern system…” For me this is the key message why it takes so long to decrypt this 4th message. What is modern? Like in 1586 the whole world is trying to move or replace letters back and forth. Is this modern? As Jim Sanborn has shown in other works of art (reduced 7 Bit ASCII), I concentrate on “digetal” or “binary”, whatever you want to call it, eg. ASCII code. Exactly how DYHAR can be interpreted. As a reduced 5! Bit binary ASCII Code. By the way the Berlin Clock based on a system of 5 and eeeeeeeeeeeeeeee! is the 5th letter of the alphabet. DIGETAL. Mr. Sanborn just shouts out the 5 and nobody notices…

    I call this the other Kryptos alphabet.

    It is on the statue.

    I think I have found what is hidden in Kryptos.

    KRYPTOS means hidden

    What is hidden?

    WHA t is your position

    idbyrows – wjllaetg
    inbyrows – wzllaetg
    xlayertwo – swzllaetg – xljyertwo – s L j yertwo

    desparatly – desparatEly

    WHALE

    Thanks to a post in Elonka Dunin’s Kryptos group I realised how the L clue works.

    WHALE

    Whale and the number 42?

    I finally realized the above thanks to a post by jezail santhon in Elonka’s Kryptos group.

    Whale makes me wonder if the Beluga whale was meant.

    This species was used duing (and after) the Cold War to locate submarines.

    WHALE BELUGA CAVIAR,

    Mister Scheidt did say he saved the best for the last.

    Beluga caviar would fit perfectly tht description.

    If you use the standard alphabet which is present on the statue you would have 6 letters from wich letter 2 and 5 (A) are cryptograpic nulls.

    In other words the source remains the same, This could confuse a cryptanalyst trying to decode a letter which is not encoded.

    If AHAB points to WHALE.

    and What is your position points to Whale as in :

    WHA t is your position

    idbyrows – wjllaetg
    inbyrows – wzllaetg
    xlayertwo – swzllaetg – xljyertwo – s L j yertwo

    desparatly – desparatEly

    and Mister Sanborn is talking about the rising of the Oceans and that he wants to start a fundraiser for climate science then you could convince yourself that you have found a clue.

    But what about the other missing letters?

    Interpretatu is missing ION,

    Add the L for LION, perhaps Whale Lion per the double L?

    The NSA has an annual gathering (employees only) which has (had) a logo of a Sphynx with a satellite dish on its head.

    NSAIMXU does show up in K4.

    What about the fact that in K2 after decoding the number 42 shows up?

    A very suspicious 42 as in DB or (great) PR.if you spell it out.

    Prominent fiction author?

    Douglas Adams.

    He has the exact same species of whale in his iconic book.

    FitnezzJim made the following observation :

    Observation: What is your position 18 character string, 12 unique characters.

    TWO pointed out that this could spell AHAB.

    How does that work?

    Number the alphabet as follows :

    A = 1, B = 2 and so on,

    FitnezzJim counted 18 letters and 12 were unique (non double) in What is your position.

    1812

    1 = A
    8 = H
    1 = A
    2 = B

    In fact this is steganography.

    This is how you can hide information in text sentences.
    Usually short pieces of information,

    In this case unique and non unique letters were counted.

    Anorher example is counting even/odd letters or low/high letters.

    A = 1 odd
    B = 2 even
    C = 3 odd

    A – M = low
    N – Z = high

    Prison or Pow codes are usually based on systems like these.
    They are very, very time consuming but if you have nothing else to do than doing time itself?.

    I am taking the lead on this theory from the last morse segment on the landscape piece that is not solved either. Digetal Interpretatu is the hint I am working with, converting the text of K4 to morse.

    This is obviously something that has to do with the puzzle, and each of the previous ciphers – K1-K3 – are compounding to this point using the previous methods and carrying through into the next templates leaving a key for the next, accumulating the pieces for the final end in Layer Two and the overall theme of the puzzle to be found.

    I am guessing this is where the morse comes into play. I am assuming that the cipher is broken from the use of these previous clues of the Kryptos Pyramid and the reconfiguration of the

    Taking the Ciphertext of K4, I am assigning a dot to all the vowels and a dash to consonants.

    Then taking the counts of the letters from dot to dot….leaving me with a numerical sequence of: 4,1,2,3,4,2,18,10,5,5, 2,1,2,25,3,2,1,1,1,3,2

    This leaves me with a series of possible ROT values for each segment that is divided between the dots or stands for a key of some sort that is applied to the ciphertext and acts as a variable in it’s alphabet or it’s substitution.

    Using these Morse segments and ROT values I get a new set of ciphertext to work with. The (YYXZVOSAA) is the NORTHEAST location and (OZQWUU)(NAGQL) are the BERLIN CLOCK locations.

    Now to try to brute force a solve and work on variables like keyword applications in vigenere layouts to get the hints right and convert the rest

    Note: when laid into the worksheet beneath the original ciphertext, the layout of the old and new one combines along the left edge to spell out OKIQQEUSIF

    Michael, I find what you’re saying here pretty fascinating. I’m curious if you’ve had any further insights since your last post or if you’re willing to further expand upon how you derived #18 or what you submitted to Jim.

    I haven’t been able to recreate your results, but have an idea on your methods.

    Happy to chat offline as well if you have a contact. Cheers!
