THE CRACKPROOF CIPHER

8/10/2019

 
THE 340 CIPHER WAS CRACKED ON DECEMBER 3RD 2020 BY DAVE ORANCHAK, SAM BLAKE AND JARL VAN EYCKE, SO THIS EARLIER ARTICLE SHOULD BE VIEWED IN RESPECT TO RECENT DEVELOPMENTS.

Unable to solve the 340 cipher and crack the message (in which I'm not alone), my only recourse is to try and prove that the 50-year-old cryptogram is unsolvable. I cannot do this on my own, so I need the Zodiac Killer to give me a hand and show me that it's not a valid cipher in his own words. The Zodiac Killer only gave us two visible 'crucifixes or crosses' (without the circle) in the cards and letters, throughout his entire correspondence with the newspapers. We can assume he did this for absolutely no reason whatsoever, or these two 'crucifixes or crosses' had a purpose. The two crosses were present in two consecutive cards - the '13 Hole' Postcard on October 5th 1970 and the Halloween Card on October 27th 1970. Both these cards also contained a hint that something was unsolvable. The '13 Hole' Postcard contained the phrase "Fk I'm crackproof", while the Zodiac Killer fashioned "sorry no cipher" in a cross formation on the envelope inner of the Halloween Card. If these statements are relevant to his ciphers, then we need to marry up the design of each card to his codes. Before we start, it must be noted that PARADICE and SLAVES in the cross formation is made up of 13 letters (the A pivotal to both words), but individually both words contain 14 letters - the total highlighted on each card. 

In the image below with respect to the '13 Hole' Postcard, you will notice that the Zodiac Killer has carefully positioned the cross beneath the number 13 - and we know Paradice and Slaves contains 13 letters in the cross formation. This is placed approximately in the center of the postcard with text either side. The 13 characters identified on the 340 cipher as Paradice and Slaves exactly mirroring this formation. Below the number 13 and cross on the postcard is the pseudonym Zodiac, accompanied by his crosshairs, almost mirroring the 340 cipher formation. The most notable feature on the 340 cipher is the corrected sixth line involving the letters F and K. Highlighted with a blue rectangle on the '13 Hole' Postcard we have "Fk I'm crackproof" written upside down. All we have to do now, is rotate the '13 Hole' Postcard 180 degrees clockwise to correct this text, so it can be read in the standard way. The corrected "Fk I'm crackproof" would now be present in the top right quadrant, just like the correctred FK in the 340 cipher.        
Picture
The Halloween Card also has the cross formation of Paradice and Slaves. This not only mirrors the "sorry no cipher" formation he provided on the envelope inner, but mirrors the 340 cipher formation also. In essence, the Zodiac Killer is telling us by extension that the 340 cryptogram is no cipher. Two consecutive communications, probably close to the anniversary he created the 340 cipher, and both designed to reveal the hidden crucifix or cross within the 340 cipher. Throw in the four By's in each quadrant and the pseudonym Zodiac from the '13 Hole' Postcard, along with "Fk I'm crackproof" and "sorry no cipher", and we have the Zodiac in his own words admitting the 340 character cryptogram has no solution. On the other hand, the Zodiac Killer is widely believed to be a liar - so maybe there's a message after all.

But just in case, let us stick "Fk I'm crackproof" into his third cipher and see if that's unsolvable as well.        
Picture
The Zodiac Killer again uses 13 characters/letters in his design, with the feature of three circled 8's. The circle and number 8 can be used to represent infinity or something of a cyclic nature. The cipher came with the handily placed K and M in the center of the code. All we have to do is place "Fk I'm crackproof" into place using these two letters (shown in blue), and in an unusual stroke of luck, the phrase is cyclic in nature. In addition, the three 8's (shown in green) just happen to begin each element of the phrase "Fk I'm crackproof" (Fk, I'm and crackproof). The Zodiac Killer may have twice told us his ciphers were unsolvable in the '13 Hole' Postcard and Halloween Card, but here he simply wouldn't shut up.

"This is the Zodiac speaking. By the way have you cracked the last cipher I sent you. My name is FK, I'm crackproof".

Hey you, it's been a while so thought I would drop by mate to let you know that a Zodiac Case Legacy documentary is being put together by An oscar winning Exec Producer. The company are based in London and the director is coming up with an Audio sound Recordist to interview me about suspect Kane and my voice will then be used to Narrate the segment on Kane.

I know, Richard, I know! Your thinking:

"What a terrific example of Brilliance You are Welsh!"

Well it's is nice of you to say so Rich, far too humble to suggest it myself obviously. 😉

Now, before you ask me for my autograph, do you want me to PM you the details I know and have so far?

And in all seriousness Rich, how you been keeping? Everything Ok?

Richard
8/11/2019 12:11:27 am

Hi your Royal Welshness, I am fine and it's nice to hear from you again, particularly because you are moving in the higher echelons of TV and rubbing shoulders with the red carpet brigade. Absolutely, send me the information anytime and fill me in. I hope things go well, but don't forget to visit my humble site from time to time. Cheers, Richard.

Alex Lewis

Red Carpet brigade Rich, or Red Phantom Carpet Brigade? Anyway, hers is the Initial email. . .

"Hi Alex,

My name's Charlie Lyne and I'm a documentary filmmaker based in London. I'm currently working on a film about the legacy of the Zodiac case, and I was hoping you might be willing to speak with me about Larry Kane, and your work seeking out and gathering together the evidence against him.

The film is funded by Field of Vision and exec produced by Oscar winner Laura Poitras.

I've spent most of this year reading everything I can get my hands on in relation to the various prime suspects in the case, and your very thorough post on Kane is by far the most concise, clear account of the evidence against him I've seen. I'd love to interview you about it all if you'd be willing?

All the film's interviews are being recorded audio only (they will later be illustrated with archive footage, reconstruction, etc) so it would only involve me and a sound recordist travelling out to you at a time of your convenience.

(You'd also be our first UK-based interviewee, which would certainly make for a nice easy journey for us!)

Let me know if you have any questions about the project, or want to hop on the phone to discuss it further.

Thanks,
Charlie Lyne

----

New: Lasting Marks — winner of Best Short, London Film Festival 2018." Email end.

Now obvious im hoping 'Sound Recordist' isnt Cockney Slang for 'Zodiac Killer' cause I will invite him in and I'm afraid you see Rich th0en... Then it won't matter how many times you request I stop by, one will not be able. Too busy i shall be with being preoccupied with being dead.

I'll be in afterlife having been oneno the Collected.

Richard
8/11/2019 01:56:48 am

Maybe it's Lawrence Kane's son in disguise, armed with a Beretta and seeking retribution for your slanderous blog post on his father. The red carpet treatment may mean something else entirely. The sound recordist may be code for Boom. If so, it was nice knowing you Alex. Anyway, wishing you well and don't forget to drop in from time to time - and always remember your roots and where your humble beginnings began. I don't want to have to make an appointment to see you in the future. Your humble squire, Richard.

Dear His Royal Majesty...

I have a day / date me and Charlie agreed & locked in as the day he and the soundman are coming to do the interview. I thought when he asked me how Friday, Sept. 27th sounds that he knew the significance.

I replied "sounds good to me, let go for it and I'll assume you know already that Sept 27 is the anniversary of the Zodiac's Lake Berryessa stabbing of Bryan & Cecelia?"

He wrote back that no, He didnt saying it was a coincidence and, He added, he is getting used to this kind of thing happening with Zodiac case as he said things like this seem to be happening a abnormally high number of times in his travels & research for this Z project. 🙄

Richard, I am presently trying to work out how many combinations of possible column and row transpositions there could be for the 340. Then of course you would have to turn it 90 degrees and do the same, turn it 90 degrees again, and then again. And if you consider looking at backwards transpositions, or maybe transpositions based on halves or quadrants, the likelihood of finding the correct combination could end up being billions to one. And that is only if we consider it a homophonic cipher and presume it may have been transposed. It could in fact be another kind of cipher altogether, including something really difficult like a cardan grille or a one-time pad, and even then it might be based on different rotations, for example.

Think of it this way, if you can see the end of a tangled ball of yarn from the outside, it is often possible to untangle the ball because you have a clear starting point and reference point. Basically you can see how to go about untangling it, because you can "reverse engineer" each tangle. But when it comes to the 340 we are really as if we are positioned inside the tangled ball, trying to unravel it from the inside out. We really have no reference point, no starting point, so no idea where to begin. All we know is it fails as a basic homophonic and attempts at polyphonics have so far proven just as fruitless. Also, once we get into the domain of polyphonics, the variability means it is impossible to know for sure if that was what the Zodiac intended.

Norman McCann
8/11/2019 05:41:03 pm

It's fairly easy to calculate, just multiply the factorials, in other words each row or column by each of the other ones in the sequence. So for 20 rows, the sum is 20x19x18x17x16x15x14x13x12x11x10x10x9x8x7x6x5x4x3x2x1=

This from Dave Oranchak ---

The number of ways to arrange the 20 rows is 2,432,902,008,176,640,000 (about 2 quintillion, or 2 billion billion).

Number of ways to rearrange the 17 columns is 355,687,428,096,000 (about 355 trillion).

But if you allow rearranging both rows and columns, the number of possibilities is 865,352,658,097,942,644,066,877,440,000,000 (about 865 nonillion or 865 thousand billion billion billion).

Number of ways to randomize 340 characters = far too many to comprehend.

So to quote that guy from Mythbusters: "Well, there's ya problem!" :-)

Sigmund
8/10/2019 10:38:20 pm

PART 2:

All I know is that if I combine the two ciphers together and treat them as a single cipher, run this in software as a homophonic substitution, I do get random "words" in the 340. The problem then of course is that the 340 has a lot more symbols than the 408, so the software has to assign letters for these symbols. Then we are faced once again with the problem of variability.

I do wonder if perhaps LE or Harden did try some basic substitutions using the existing code. If they did they may have even obtained a similar result, in which case they may have wondered if their prime suspect was trying to communicate obscure words relating to his identity or surroundings. So you find random words among the gibberish like:

eagnSENTionssRONa

and

alotint IN erbiette
adearl SANE nedhmao
gdoe TTENNESEE laht
eehan RED inatokahe

Of course such words could point to Toschi's prime suspect, who lived off Tennessee Street in Vallejo and who had a brother named Ron.

But of course we have absolutely no way of proving this because of the vast problems of variability. We do know that other serial killers like BTK designed similar ciphers that were designed to provide clues based on random words. A dead giveaway in BTK's cipher was his inclusion of the words "LOST PET" for instance. BTK was at the time the city's dog catcher.

The thing I find interesting is that the final line of the 408 is random gibberish, and if the 340 may be nothing but random gibberish, perhaps the two ciphers were originally just one large cipher. Why he would encode one page sensibly and the other page as gibberish is difficult to say, except perhaps he thought it would make the cipher a lot more difficult to crack. But of course that goes nowhere to explain why he then chopped the cipher in two and then chopped the top section into three before mailing them out. But it could provide a reason why he added a lot of extra symbols to the 340, even though it is smaller. I think the 340 may share a geometric and mathematical similarity to the 408, and contain pivot points, but this is possibly just a ruse. It is designed to look like a real cipher without actually being one.

Richard
8/11/2019 12:30:59 am

As you know, I totally agree with this possibility, but I will leave cracking the cipher to code experts, hoping a solution will be found. My expertise is certainly not as a cryptographer, which is why I'm taking the nuts and bolts route of a Zodiac Killer who was duping us all. As you have pointed out, a small change to the layout can vastly change the outcome in the decoding. I will let others chip in on something I am less than experienced in. I am taking the alternative route of Zodiac responding directly to the American Cryptographic Association and creating "something, however complicated". They quoted Edgar Allan Poe "that any cipher created by man can be solved by man". So, possibly Zodiac decided to create something other than a cipher - the proverbial poke in the eye if you will. Hopefully somebody more in tune with cipher decoding can chip in, because my knowledge is sadly lacking in this field. Maybe I shall brush up on this subject as my next project. Did you watch the Zodiac Killer Facts video on the 408.
https://www.youtube.com/watch?v=BAAgDSQoNDI

Sigmund
8/11/2019 01:04:27 am

Thanks Richard. The Paradice/Slaves motif is interesting, but I am sure this kind of "window dressing" could easily be added later, even to a genuine cipher, simply by re-assigning different symbols for different locations.

The John Rose partials continue to intrigue me. I remember suggesting to a friend the possibility that the 340 may be merely intended to reflect the symbolism in the Halloween card. My friend basically said "What would be the point?". I can only agree. Why would he simply re-hash something he had already done elsewhere, or are there other "clews" floating about in there that we have missed? Or did he just consider this a cool idea and he had it stuck in his mind at the time?

Richard
8/11/2019 01:41:17 am

Yes, I certainly accept the contention that the cipher can contain a coherent and legible message, while also containing the features such as paradice, slaves and Zodiac as "window dressing". It isn't that difficult to create the style and add the message afterwards. The only thing I'm wrangling with, is the wording "Fk I'm crackproof" and "sorry no cipher". He could of course be stating to police he is crackproof and they will never catch him, but why the FK. That is why it's unusual the only corrected portion of the cipher involves F and K in close proximity, and the K is reversed (and smaller) just like the reversed Fk in the '13 Hole' postcard. Was this yet another coincidence? But we both know it could be. I just don't like too many coincidences - a word always conveniently around to explain away everything. Then we have "sorry no cipher". The obviousness of telling us there is no cipher in the Halloween Card equally doesn't sit well - it could be the simple answer - but why write it in a cross formation twice. I wish somebody would supply a reasonable answer to this, because I will be only too happy to ditch the premise of a fake cipher. The Zodiac Killer could easily have written "sorry no cipher" just once, and that would have sufficed. I cannot reconcile this crossed design just done for absolutely no reason. While I fully accept the Zodiac Killer can create a 340 cipher with "window dressing" and message running in tandem, the Fk element of "Fk I'm crackproof" and cross design of "sorry no cipher" need a rational explanation, otherwise you'll never hear the last of my incessant ramblings and musings. These are in essence the crux of my argument, coupled with an egotistical killer who I contend would have found it extremely difficult to sit on a solution to the 340 cipher for 50 years and counting (if alive). I know I couldn't have resisted the temptation and I don't consider myself in the same bracket as Zodiac. The itch to reveal the cipher to the world, in essence, torment in itself. I have long thought October 27th 1970 may have been the anniversary of the cipher's creation and Halloween was the perfect time to reveal his trick to the world, rather than the treat we hope for on Halloween. My suspicions may be unfounded and I don't rule out a complete and coherent message in the 340 cipher, but equally I wouldn't put it past Zodiac telling us it wasn't a cipher after all, but disguising this message also.

Sigmund
8/11/2019 04:54:08 pm

Hmm, I can't really buy that Fk thing. Far too obscure. Also you are putting a lot of faith in the 13-hole postcard, which was an unconfirmed correspondence.

JD
8/12/2019 09:58:18 pm

Hi Richard. Certainly FK is in the cipher, but I tend to agree with Sigmund that it is window dressing; perhaps even a bit of misdirection. Sorry that I can't get away from the cattle brands, but, if as proposed by others he did indeed use cattle brands, I find it interesting that FK is a Rogers & Comstock Cattle Brand, and the little doo-dad at the end of the "Bates letter" is a G.W. & R.A. Phillips cattle brand. The cipher might have merely provided another opportunity to highlight a clue, or the answer, to be found elsewhere.

Tom1
8/11/2019 06:31:51 am

I am certainly no expert on ciphers and related matters, but does not the above analysis of the 340 indicate it is not a true cipher per se, but a word puzzle instead? Is that explanation just to simple for most?

Richard
8/11/2019 06:44:01 am

A disguised word puzzle would sum it up Tom. Certain words, particularly "paradice" and "slaves" placed within the 340 cipher, with clues to their presence one year later. My guess is the majority of the 340 cryptogram has "no cipher", as Zodiac alluded, but just a few words embedded within it. It could be a word puzzle and genuine cipher, as the two are not mutually exclusive.

Sigmund
8/11/2019 04:49:53 pm

Or, alternatively, he just wanted people to believe that. Having a superficial layer of meaning that is easily interpreted can provide a superficial ruse. The real cipher remains hidden much deeper within. This was something spies did regularly to fool their opponents. Not that I am suggesting Z was a spy of course. But when people say "Wow, I've solved it, it was SO simple, it was Paradice & Slaves!", the Zodiac could just sit back and laugh at their all too feeble attempt. Could be you are merely falling for a superficial smoke and mirrors illusion, i.e. you are only seeing the window dressing and not what is inside the house.

it is unfortunate some of these Zodiac Documentaries have not reached out to you (to my knowledge), Given your vast knowledge of the entire case. You are probably the most knowledgeable Zodiac researcher on the internet.

Maybe it is because you are in England and the distance is a problem.

Shawn

Richard
8/11/2019 03:12:05 pm

Well thanks Shawn, that is very much appreciated. The English thing could be an issue when appearing in documentaries, but truth be told, if the documentary or podcast was primarily focused on a routine retelling of the case, I'm not sure I'd be interested. There are enough documentaries and podcasts on the internet to thoroughly inform Zodiac newcomers to the case - and Michael Morford's and the Monster podcast did a thoroughly good job. I did enjoy Michael Butterfield's video about the 408 with David Oranchak. But the harsh reality, is that when Michael Butterfield is invited onto podcasts, the interviewer always asks that routine questions and obviously you get the routine answer. I would like to be the interviewer and ask the main Zodiac researchers questions that have never been asked them before. That would be interesting - challenging them or taking them out of their comfort zone. I personally would like to see documentaries exploring new angles on the canonical and fringe crimes, along with the ciphers and cards, and featuring an array of the outlier letters. I certainly think a certain amount of Zodiac documentaries and podcasts are very useful when well done, but I feel the routine retelling of the case has reached its watershed now.

Richard

Oh. and no, nobody has ever contacted me for either a podcast or documentary Shawn.

Alex Lewis
8/17/2019 05:13:47 pm

Ah well it's funny you should say that I Rich, this Documentary is not retelking the case again as I did ask the director Charlie, fairly obviously, what he wanted from Me for the Docu itself and he stated his crew have not researched anything for this case and he himself had solely for the need to ask follow up questions etc.

He said this docu is one where he wants The case and top suspects to beyond by, in Kanes case, Me and the same will be for the other suspects their segments will be told by the people who have researched them and made cases for their being Z.

This won't be a bias for a certain suspect or other. The Director has no agenda, no Bias not a reason to promote suspect A or B. He said he wants the Zodiac case to be told by us in the online Amateur Community.

They are massive. And have plants and offices all over the world.
Fluor Kuwait, Korea, Kitimat are just some of of the possible Fk's

They are all powerful - so they at Fluor should expose what they know on Cheney's time line. If Don is the Zodiac they will know.

Kinematicians study the trajectories of points, lines and other geometric objects. The study of kinematics can be abstracted into purely mathematical expressions. Kinematic equations can be used to calculate various aspects of motion such as velocity, acceleration, displacement, and time.

Could this be what the k stands for in Fk?

The only thing of Don Cheney I found that he worked for Fluor as a Mechanical Engineer, type was as a kinematician.
Which may explain the fascination with the pen light and where the bullet goes etc.. He went to Cal Poly in the same place where Art Allen worked as a teacher for 10 years - San Luis Obispo. Maybe the room-mates Don, Sandy and Ron Allen set up Art as the Zodiac. And perhaps one or all of them were the actual deviants. Maybe ALA was their patsy.

BB

Richard - Don Cheney's pictures here at age 32 in 1960 shows a pronounced widows peak.

BB
8/15/2019 01:55:32 pm

The answer to the z13 according to Keith Massey, PhD is
Art Leigh Allen

Of course it does not say Donald x Cheney. Since Don wanted everyone to think that Arthur was the Zodiac.

Donald Cheney went to Cal Poly Pomona in 1960 when the Football team - On October 29, 1960, chartered a plane carrying the Cal Poly San Luis Obispo football team, hours after a loss to Bowling Green State University, crashed on takeoff at the Toledo Express Airport in Toledo, Ohio. Twenty-two of the 48 people on board were killed, including 16 players. The Northern Cal Poly campus did not offer a masters program until 1967 - which was the reason that Cheney went south or was he on the lamb? The Cal Poly San Luis Obispo State University was established in 1901. The two campuses they became independent from one another in 1966. I wonder if there were people killed in the Pomona area at that time.

There needs to be an extensive investigation of Cheney - at least half the size of the Allen inquiry.

Sigmund
8/15/2019 04:14:26 pm

Yes BB, the letters to form Leigh's name can be cycled in rows and columns, using "L" as an anchor symbol. It is possible to mathematically calculate a very good fit for Leigh's name. The puzzle could be seen as algebraic in design. However this is to presume it is not a regular homophonic cipher, in which case it is far too small with too many variables to reliably produce a single name.

One question: Would Cheney have been smart enough to design such a code, and would he have had any training in codes, such as through military training? It always interests me that Grant knew code breaking and his writing style was very close to Zodiac, yet as far as we know Grant and Leigh were not known to each other. Graysmith tells us (in very anecdotal terms) that Leigh may have known a man by the name of Fred Manelli, but I have never found any clarification for this connection. Fred Manelli certainly lived in the same area as Leigh at the time. A lot has been made of Fred's creative writing, which often hints at dark subjects dealing with rape and murder and he often wrote in the first person. There is certainly enough in his writings to show that he had a rather unhealthy interest in such subjects. He only became a suspect after he was killed in a head-on collision on August 24, 1976 on Highway 12. Crime scene investigators discovered sadomasochistic drawings he had created depicting a former student, Kim Wendy Allen among his belongings. Kim Wendy Allen, 19, was murdered on March 4, 1972. Witnesses last saw her at approximately 5:20 pm hitchhiking to school near the Bell Avenue entrance to Highway 101, walking northbound and carrying a large wooden soy barrel with red Chinese characters on it. Her body was found the following day down an embankment in a creek bed twenty feet off Enterprise Road in Santa Rosa. Semen samples were recovered from her body which should have helped identify her killer, but to date there have been no new leads. I have never been able to verify if Kim Wendy Allen was related to Arthur Leigh Allen. It would appear that the surnames are coincidental.

If Kim is related to Ron and Art Allen it would tie everything together.
Don Cheney was a math expert with a graduate degree from Cal Poly
He was a Mechanical Engineer and worked for Fluor (on pipelines).
With a main objective of making the pipes crack proof. In California the number one interest is water. The companies next HQ was Texas where the main concern is for oil. But they do all gases and most liquids. Each substance and each place require differently made pipes. Cheney is a far better fit for the Zodiac than ALA.

Det. Balwart believed that Cheney was more involved in the case than he let-on. Don basically said I put my prints on things related to the Zodiac case. Also I licked the stamps and the envelopes. Got rid of the boots and some other stuff. Stuff like maybe guns knives and or even bombs is what he probably meant. And, this is why after Allen died Don should have become the #1 suspect and not Allen. It was Cheney with the motive means and opportunity. And, not ALA. Allen was on parole. He was being watched. He was not the Zodiac.
