Since publication of the Da Vinci Code interest in Kryptos has soared. The Kryptos-related coordinates hidden in the book's jacket, plus Doubleday's online challenge to Uncover the Code, and the hint that Kryptos will somehow feature in Dan Brown's next novel, have made Kryptos into a growth industry. Last Spring I received a series of emails seeking information on my progress with Kryptos from a party who had acquired a copy of an article on Kryptos that I had written in May 1999 titled "A Courtyard Interlude" which was featured in the Fall 2002 issue of CIRA (see below). The article recounted my progress in the spring of 1997 cracking into and partially solving two of Kryptos three cryptographic systems. The article disclosed my original notations regarding possible solutions to the unbroken Kryptos cipher system, and revealed irregularities I had discovered in Kryptos inscriptions which may be clues for this final unsolved cryptogram.

A Courtyard Interlude as it appeared in CIRA, the newsletter of the CIA Retirees Association.

Reference to my1997 Kryptos breakthrough first appeared as a footnote in the Spring 1998 PHOENICIAN the newsletter of the PHOENIX SOCIETY the NSA equivalent of CIRA. As indicated in a letter published in the Fall 1999 PHOENICIAN, I was unable for lack of time to break out a complete plaintext decryption to the first (polyalphabetic) and the second (transposition) systems, but with pencil and graph paper, I was the first known to break into these two systems, and my April 1997 success jump-started a revival of interest at the Agency. It has been reported that two NSA's had broken Kryptos as early as 1992, but if this is the case it was never reported to CIA nor to the NSA Phoenix Society of which I am a member. 

The original "A Courtyard Interlude" article, was written back in May 1999 and first appeared in the March 2000 issue of PERISCOPE the newsletter of AFIO the Association of Former Intelligence Officers. It has most recently appeared in the Fall 2005 issue of CRYPTOLOG, the newsletter of the U.S. Navy Cryptologic Veterans Association (NCVA), and is updated in the Winter 2005-6 issue of CIRA, and the Winter 2005-6 issue of the PHOENICIAN. The article was not classified, but these newsletters are not distributed to the general public and my 1997 breakthrough on Kryptos has remained in the shadows. However, a recent Maine newspaper article was picked up by the AP wire, and I was interviewed by phone and e-mail for an article in the Sunday London Times of January 01, 2006, titled "Codebreakers Crack the DaVinci Sequel Mystery." In response to the interview and the article, I submitted a letter to the editor on January 01, 2006.

As a contributor to M.E.Sharpe's new 2-volume Encyclopedia of Intelligence and Counterintelligence, I was interviewed by a May 2005 Maine periodical and a July 2005 Maine newspaper. One of the encyclopedia pieces I contributed was on a legendary CIA operative named Tony Po, aka Anthony Poshepny. I had first written about Tony for the Summer 2003 CIRA magazine, which led one interviewer to the Fall 2002 article on Kryptos.

This News Article was reprinted in the Phoenician (Spring 2006).

July 2004 News Interview on Operation ELSTER (Magpie). The "old spook" uncovered Nazi agents WWII mission, hidden for 6 decades, to sabotage Manhattan Project. See: www.captaind.com/spies.html

Pursuant the above-mentioned email inquiry last Spring, I reviewed news media articles on Kryptos over the past half-dozen years and discovered that entrepreneurs have made Kryptos an online enterprise. Browsing a virtual explosion of Kryptos related websites I recognized language identical to my observations and notations made on Kryptos Part IV in "A Courtyard Interlude," and in an "Update on Kryptos" published in the Summer 2000 PHOENICIAN, but nowhere did I find any attribution to these original sources or any reference to my 1997 breaks on Kryptos. I hope to visit the CIA campus this fall to test two spatial setups, one of which I feel may unearth Kryptos final secrets. Meanwhile, with the urging of CIA and NSA retirees I am posting the following Kryptos analysis timeline from files boxed away in my attic.

March 21, 1997 - I examined Kryptos cipher and Vigen're panels, and the clues in the courtyard and outside the NHB west entrance. Copying by hand the top half of the cipher panel, I discovered two conspicuous levels of repeating sequences in the upper section, and pointed this out to the CIA PA staffer with me. It seemed a good guess that this section of the cipher panel was intended for application to the attached Vigenre panel.

March 23, 1997- Letter to CIA official who had invited me to be on a Woman's History Month panel. The name blocked-out in first line is CIA PA officer with me in the courtyard March 21st. "Mardi" is my wife, Marjorie Hayes Byers.

March 27, 1997- Email from CIA staffer with me in courtyard March 21st. The "27 March item" was an email attachment with information for the CIA official organizing the program for Women's History Month. The "back lot" is the NHB courtyard. The "second level" is the lower sequence of polyalphabetic repeats in the top cipher panel.

April 2, 1997 - Package from CIA official, in response to my request for a copy of the Kryptos cipher inscription, only the top half of which I had copied. The package included a CIA bulletin titled "The Art of Cryptography" containing the Kryptos Inscription and Vigen're Table and CIA observations on Kryptos. The package also contained a news clipping from Apr.1991 INSIGHT magazine, plus an original CIA 8-10 color photo of Kryptos.

April 4, 1997 - Letter from NSA Phoenix Society with a copy of CIA bulletin "The Art of Cryptography," in response to my phone call requesting a copy of the Kryptos cipher inscription.

April 1997 - Letter from James Sanborn with copy of the cover Dec.1991 CRYPTOGRAM journal of American Cryptogram Association, and a 1990 News Clipping of the Kryptos inscriptions. This was in response to my phone call March 30th requesting a copy of the Kryptos cipher inscription.

April 1997 - Letter from ACA, American Cryptogram Association, with CRYPTOGRAM issues Dec.1991 and Apr.1992.

April 10, 1997 - Email to CIA PA staffer who was with me in the courtyard. Names and information unrelated to Kryptos are blocked-out.

April 11, 1997 - Letter to CIA official requesting photos of clue structures. Names and non-Kryptos information blocked-out.

April 12, 1997 - Email to CIA staffer re photos of clue structures and CIA's 7x10 Kryptos Color Print.

October 1998 - John VIII-32 inscription in CIA lobby I hastily copied on CIA/OS notepad to confirm 49-letter count, pursuing my early 1999 theory that Kryptos unbroken K4 cipher could be digraphic (bilateral substitution), borrowing the final "Q" from K3 to make 98 letters (49 digraphs), encrypted with a double "Playfair" or a "Checkerboard" cipher with a 5x5 matrix (I/J in one cell), using keyword Kryptos mixed-alphabets, and an "additive" key. Without a super-encryption additive a cryptanalyst with "machine support" (computers) could easily have broken K4. Given this lack of success, I turned my attention towards an out-of-the-box "spatial" procedure, primitive by modern elliptical encryption standards, yet able to withstand computer attacks. Hopefully you will see more about this as soon as I am able to travel to Virginia following hip surgery.

December, 1999-The Kryptos plaintext message contained in Part I (ciphers K1 & K2) and Part II (cipher K3) as it appeared in December 1999 in CIA's inhouse edition of Studies in Intelligence.

January 1, 2006-London Sunday Times article from December 31 phone and e-mail interview with Richard Gay.

January 2, 2006-Letter to the Editor London Sunday Times

Subject: RE: A Fellow Crypie
Dear Ed,
Nice to hear from you.
Yup, I knew you were the brains behind Sanborn's ciphers. I had this to say
in my May 1999 Kryptos article:  "The cryptographer who designed these
cipher systems is to be complimented on the historic craft and artistic
touch he brought to the statuary, without which it is several tons of
copper of equal interest to a scrap metal dealer."
The article "A Courtyard Interlude" was the cover story in CIRA (Fall 2002)
and is featured in the current issue of Cryptolog (NCVA, Fall 2005).  It
appeared in Periscope (AFIO, Spring 1999), the Phoenician (NSA, Fall 2000 &
update Winter 2005-6), and in the Forum (FAROG, Winter 2005-6).
Did you read my article "Under Cover as a Franco" in CIRA? ... [CIA shop-talk not related to Kryptos] ...
When I come down to scope out K4 perhaps we can meet for coffee somewhere.
Come to the coast of Maine as my guest for a weekend at
www.inn-guide.com/tenneyhill.
Best regards,
Dick
PS:  RUMINT has it Sanborn applied his personal touch to K4.
[Note: RUMINT is a term, that I invented years ago, for Rumor Intelligence, or just plain rumor. By the way, Ed did not respond to my PS.]

April 2006. James Sanborn reveals that he omitted a letter from the Kryptos Part I cipher panel, which interrupted the decryption sequence and yielded plaintext "ID by rows." Sanborn now confirms that the correct plaintext should be "xLayer two." Thus the ending of the Part I message reads: … "38 degrees 57 minutes 6.5 seconds North, 77 degrees 8 minutes 44 seconds West. Layer two." My guess is the words "Layer two" were included simply to fill out the top cipher panel and label the second polyalphabetic layer, the one I reported to CIA in 1997 (see Timeline March 21, 1997 & March 27, 1997).

On the other hand "Layer two" could be taken as another clue to solving Kryptos Part III (K4). Reluctant to give away more secrets in responding to inquiries from journalists, bloggers, and entrepreneurs, I hinted that the copper scroll folds back upon itself, and the final "Q" from K3 moves to K4 producing 49 digraphs (Periscope, March 2000); and that sun and shadow play a decrypting role (see Timeline Nov. 5, 2005 & Jan. 2, 2006).

From the first I have not believed that K4 employs an unbreakable OTP. A one-time key maybe, but not a one-time pad. Six years ago I reported in the Phoenician (Summer 2000) and elsewhere, that keyword "Palimpsest" may suggest a spatial system for K4. I believe the elusive key to K4 is a computer-resistant mix of cryptography and steganography. Soon I hope to be able to test a stegotext-covertext formula on-site at CIA.

Hi Jim,
I know how you are hounded, but I have one question:
Does one really need to be onsite to solve K4?
Ed S says one thing and you seem to say another.
I've always assumed it can be done with a copy of the cipher transcription,
same as the other parts K1,K2, & K3.
Cheers,
Dick Gay

Subject: Greetings from Maine
Hi Ed,
...
In your and Jim Sanborn's interviews, you referred to K4 as containing "98 letters" and JS calls it 97.  Another difference is that JS said the K4 requires an onsite solution, and your answers indicate otherwise.
As an old crypie, like yourself, I would hope the merrits of K4 can stand on their own, without the need to feed the public misinformation. My guess is that K4 is a good enough system that disinformation need not be part of the puzzle.
...
In spite of JS's possible compass-clock, I have started to abandon the idea that the suns shadow plays a role... seasons and DC weather being what it is :-)  An angle projected from some other of JS's gimmiks perhaps, but not 'ol sol.
Anyway, I wish you and/or JS would set the worldwide public straight on the mixed JS/ES message:  1) 97 or 98 letters, and 2) Onsite requirement, or not.
Cheers,
Dick Gay

Subject: A Fellow Crypie
... [Responding to my CIRA Winter 2005 article updsating Kryptos] ... I guess I haven't had the opportunity to meet with you, but I encourage you to try for K4.  I will not be able to work with you as you had suggested in the article for a two-person on site procedure.
I am the cryptographer that created Kryptos.  It has been fun to observe on
the side lines.
Have a Happy New Year.
Ed Scheidt
Retired 1989
[Note: Could this be a clue, albeit unintended, from "A Fellow Crypie" that the "two-person on site procedure" is not going to work on Kryptos. In the past I suspected that Jim Sanborn messed with Ed's finished product on K4 with a bit of re-sculpturing. In my article "An October Update on Kryptos" in CIRA Winter 2005 on page 34 I had written: "The solution to K4, I believe, may require a two-person on site procedure, which I hope to test as soon as I recover from recent hip surgery. Anyone wishing to team up with me for a sortie into the NHb courtyard, I can be found at: www.inn-guide.com/tenneyhill."
Ed is mum on the subject, but I now have reason to believe that Ed's K4 cryptogram embedded in K4 is tricky enuf to stand on its own, with or without a touch of Jim Sanborn's artistic steganography.]










Stay tuned: Richard Gay's extensive personal file and timeline on Kryptos will be scanned and added to this website.
