# How To Make a Cryptex

In this Instructable I'll show how I made my cryptex.

There is already an Instructable on making a cryptex published lately, but I wasn't satisfied by that one. That cryptex was held together on the outside, like this. I prefer my cryptex held together from the inside, like this. That is by the way the 'real' cryptex, like it is used in the film. Those are harder to make.

A cryptex is a kind of lock with a password, that holds a roll of paper. Author Dan Brown said in his "Da Vinci Code", a book from some years ago, that Leonardo da Vinci invented it, to let messengers carry secret papyrus rolls that the messengers themselves may not read; only the sender and the recipient know the password. If the messenger would smash the cryptex to read the message, a vial containing vinegar which was rolled inside of the papyrus roll would also break even earlier than the cryptex itself, the vinegar would spread over the message, disolve the ink, making it unreadable.
The term 'cryptex' is actually made up by Dan Brown. I don't even know for sure that it's true that Da Vinci invented it, he never actually made one, he would have made a blueprint in his diary, but I never found that page of his diary(so I made my own blueprint, see the next step). What I do know, is that the vinegar thing doesn't work. It doesn't disolve the ink so much that it gets unreadable, it becomes only a little more vague. I tested it with Black Indian ink, several kinds of pen inks, marker pens, ecoline, pencils, and some more; it never worked, just like Wikipedia says.
In the Da Vinci Code, the cryptexes were used different than how they were meant by Da Vinci, in the story they use it as a part of a big puzzle, the answer to a riddle is the password of a cryptex, which contains another riddle that leads to another cryptex, etc. To my opinion the use of cryptexes in such a way is a bit ridiculous, the characters in the book could've just put the cryptex in the freezer so that the vinegar gets frozen, then they could saw it open without danger. But they didn't think of that easy solution in the book.

edit:
In the comments below, 'cavingboy92' came up with this genious way to make use of the vinegar vial: on the paper around the vial, don't write with ink, but also with vinegar. If you want to read the message, pour a PH indicator on it(like red cabbage juice), and you can see the text. Or you can just hold it under a low heat source like a light bulb, then you can see it too, because the acid will oxidate.
If the vial breaks, the piece of paper gets all drenched in vinegar, so it's absolutely sure that it's unreadable!
Here is the proof that it works, tested by cavingboy92.
You could also just put the same inkin the vial as the ink where you wrote with on the paper, that would also destroy the message.
If you want more ways on how you could use a vial-break-delfdestroy mechanism, read throught the comments below, there are a lot of people giving suggestions for it, and also on improving the cryptex.
Finally, if you disolve a lot of salt in the vinegar, I think you can lower the freezing point of it so much that it can't get frozen in a normal kitchen freezer, then the freeze method also won't work so easily, you would have to find a special freezer in a lab or something.

Yes the original cryptex had papyrus . Which was paper of long ago and the vinegar would dissolve the paper . Paper used to be held together . It was tree pulp held together so the vinegar would break the bond . New paper is different but papyrus was a different paper. You can try making your own paper and using a solvent that would be undone by vinegar

Interesting...
But, really with trial and error, you could crack the code...

But, i still want one

trial and error won't work. This one has over 308,915,776 combinations and only one is correct. There are 26 letters on all 6 dials. It's highly unlikely that trial and error would ever work

OMG! This is totally awesome! Oh, why did Instructables digest came so late?! This cryptex idea would fit my puzzle-present for my friend's birthday tomorrow :( guess i'll make it anyway and present him the whole puzzle a bit later :/ I still wonder where to find tubes.. though, i guess i'll try in local store for such things.. Thanks for instructable :)
merijnvw (author)  Kraplax5 years ago
Thanks. I was just lucky, three of the tubes were in my dad's shed, and one tube came from an old damaged tent. But if you are going to make it just for a puzzle, I assume your friend keeps sportive and won't try to lock-pick or break your cryptex or something, you could also make it from cradboard tubes that go around posters. Or just paper... I could think of those tubes made from paper, with 10 or more layers of paper in thickness. It wouldn't hold against a thief, but for a puzzle present it would be good!

Better late than never ;) Three (or four?) years ago i finally made it from composite water pipes (PVC+Al+PVC ones) and it turned out really great. In case anyone looks for a material that is easy to handle and work with - PVC tubes are great for cryptex!

5 years ago
Well, i looked around for other instructables about Cryptexes, but they don't look that cool. I doubt i'll follow your idea to the letter, but i guess most of your instructable would be done. I guess i wouldn't work that hard on side caps. Maybe some strong glue, but no nails, i guess.

I think in the book it said the Cryptex used a special kind of paper so the PAPER itself dissolved. And is there a way to have the inside be hallowed out so you can store bigger objects in it?

Another way you could make the vinegar vial work is is you wrote on something like tissue paper so the vinegar would dissolve it completely. I also like the idea of adding salt to prevent the freeze method. I was wondering if somebody could figure out a way to make a timed cryptex so that if it wasn't opened in time, the message would be destroyed. That would take some work, but would eventually be worth it for secret spy stuff.

thats actually exactly the point, had merijvnw read a little deeper into Dan Browns book, paper is not the material the note is written on but rather papyrus, which dissolves in vinegar, im not sure if someone else has already commented on this, but if so i just wanted to bring it to greater attention

Old post, I know.. I would look in to something electronic. Small timer (chip might work best), maybe a motor to crack the vial? Not sure how small it could be though. Sounds like a weekend project for me =)
3 years ago
In the book, pulling to hard on the ends of the cryptex actually moves a lever that has a point attached to it that presses down on the vinegar vile. When enough force is used (less force than required to break the cryptex) it cracks the glass vial containing the vinegar. this acion releases the vinegar which dissolves the papyrus.

okay cool, now how do you change the password?

I have given this thought with several designs, the best way to describe it is to make the lettered part have a piece under neath it that is an internal gear (http://www.rushgears.com/images/internalIMG.gif), with this you can adjust where the keys letters are on each letter ring. While I cannot describe this in great detail I suggest looking up how to change the code of your cryptex (the small ones Google distributed as part of their give away), the descriptions will show you all the internal workings and give the information you need.

Hello next week's project.
lkearbey5 years ago
You mention engraving on the PVC with a heated paperclip and that the fumes are harmless. It appears that the vapors from heating PVC can cause some forms of cancer (what doesn't these days though!) so it might be a good idea to do that in a well ventilated area.
merijnvw (author)  lkearbey5 years ago
Thanks for the information, I'll add it in to the text. I had my doubts about it too, but I read on another website that it's harmless. However there are researches about PVC that contradict the other. Also PVC in contact with food, some say it's unhealthy, some say it isn't.(I know that because of my other 'cat feeder' project) I'll tell them to do it in a well ventilated area like you said.
3 years ago
PVC is Poly-vinyl-chloride. Burning or melting it can give off small amounts of chlorine gas. It doesn't take a lot of chemistry knowledge to figure out the reaction of breaking down PVC molecules with heat. There may be some that say it doesn't happen. Though, I would not take the chance that they are wrong.

Hello,

Just reading through your instructable, I cant find any reference for your tube lengths? I am assuming they are about 10cm long. Can you confirm this?

Thanks
merijnvw (author)  liam_mcquellin3 years ago
I would estimate them as 13.5 cm or so, not super sure though, can't measure them now as I am on vacation. But this length is dependent of the length of your password of course, that's why I didn't include it I think. Moreover my measures are just an example, take the measures how you like, good luck!

Antitheus3 years ago
I am now making this cryptex completely out of brass, and I would like to change the password sometimes.
in the video (step 1) you mentioned you've changed the code.
I'm really curious about how you did that, since the scales are glued on the 'locking rings'
merijnvw (author)  Antitheus3 years ago
Haha, at first I just glued the alhpabet on it with pritt glue and then added lacquer over it, but because of that I could easily make a cut and then remove the whole strip.

In your case I would do it like this, maybe you already thought of this but I will tell anyway, see image:
make the alphabet strip like an extra ring with some pins on the inside that fit into 26 optionably chooseable notches on the real ring underneath. So when the cryptex is locked these rings interlock and form 1 ring, if you unlock the cryptex you could take the rings off the inner tube and then you can get the 2 parts of each ring apart and then rearrange.
This would also need the border of the inner tube holding the rings together to be removed, but ONLY if the code is inserted. I do have an idea for it, but I think that's very hard to make, especially in brass. the inner tube would have at least one cut at the beginning of the tube (I drew two), the ring holder tube needs a hole with a skew cut on one side, and the holder ring needs pressable buttons in the shape I drew. Then when the buttons are in the cut, the holder ring isn't movable, but if it's pressed in by the part of the inner tube where there is no cut (so the tube has moved and the code is broken) then the button gets pressed in far enough to be able to when given side pressure, slide through also the hole in the 2nd tube, and then get out.

nice project btw, in brass! good luck!
csim853 years ago
I Just had an idea for a multi-cryptex. It would use less pins spaced closer together and the notch that the pins slide though would not be a straight line. The rings used to input the code would be staggered every other ring depending on how many codes were implemented. Sort of like a renaissance nuclear missile launch. It would take multiple people with different parts of the code to unlock. I'll try to draw it out on paper first to see if it's plausible.
merijnvw (author)  csim853 years ago
wow that's really interesting1 I don't completely understand it, but if you have drawn it on paper please show it to me!

about using vinegar in the glass vial you have to use papyrus so that the vinegar can corode it it sys that in the da vinci code page (273) lines (17-18-19) that's why when you tried to use normal paper it did not work

Using your dimensions (because I'm lazy and bad at calculating) if you were to put a small vile in it, about how big would the vile be and how much liquid could it contain?
merijnvw (author)  Iridium73 years ago
the inside of the most inner tube has a diameter of 2cm. So what is the max diameter of the vial? 2 cm obviously. To be able to wrap some paper around it make it a little smaller. The length of the vial depends on the number of letters in your code word. To calculate the volume of a vial (cilinder) use the formula:

volume =
ground surface × length of cilinder =
PI × radius squared × length of cilinder =

The radius is the same as the half diameter, so the distance from the edge to the center of a circle.

oh ps about the changable code i just made an extremmely crude image and it simply shows how the face with the characters is enlarged and is detached from the normal ring with a peg and slot locking mechinism to were a slot is lined up with each character a matcing ring with pegs so that going on rotational symetry it should fit either way it is turned. there would need to be an equal pair of slots and pegs as there were characters a stabderd of 26 if the aplhabet was used or 36 if the alphabet and the digits 0-9 were used.also by using this method multiple rings could be made with different combonations of symbols/letters and numberscreating an endless possibitities for combonations.and finally if anyone actually makes this would they mind posting pictures or even going as to create an instructable?
merijnvw (author)  shabaki5 years ago
Yes they were also talking about this in step one, search for 'Jefferson wheel' I don't know much about that wheel, but they said that if you make something between the Jefferson wheel and the Cryptex, it would be cool. I think they meant something like you made up, so cool concept! however I would make it like the image below, only then with the inner ring having 26 teeth instead of 20, then you can put it on every letter. On yours there are only four possibilitiet per ring, of course you can swap them, but still it woul be a great puzzle to form another word and the chance would be small you could form a word you want. Maybe I'm going to make a Cryptex 2.0 Instructable later on. I have found some other metal tubes, that fit in eachother aswell, and those are a lot smaller than the ones I used in this cryptex(the biggest tube is 2.5 cm. in diameter!) So I could put that cryptex in my other cryptex like Saunière did, that would be a really precise job and if I would implement the Jefferson thing aswell, I would blow away Saunière and they would call me the master builder!

Here are some pictures of one of the "Nested" Cryptex(R) Security Boxes or a smaller box inside a larger box. These are custom made by hand out of Cararra White Marble, solid handpolished brass and black marble... The display box is Bolivian Rosewood with a pop-out inlay. There is also the vial of vinegar and papyrus document. Having a little trouble posting images due to file size restrictions... so there are only three pictures. Still too big! Ah, I see, I'm trying to upload very high res pictures. Let me try again with low res pictures. Hopefully there will be enough detail.

As you know by now, vinegar does not disolve papyrus so the vial and papyrus is purely cosmetic on this box (for safety purposes and to avoid lawsuits I won't make boxes for clients with anything that could be considered hazardous, I've done it with the self destruct mechanism, but it's too dangerous, will burn your hands and is pretty much a one shot deal as it destroys the box at the same time). But everything else on these boxes is fully functional and they are secure (barring smashing it into a million pieces or as one person said "Going Dr. Freeman on it with a crowbar") with anti lock picking features, etc.

OK, I'll see about getting some pictures of that at the same time. People are always asking about that stuff anyway so I might as well get those pictures for my website anyway. I was going to take some shots today outside with natural sunlight, but I woke up and it is overcast and pouring down rain (not uncommon for Seattle). So as soon as the weather gets nice, I'll take some pictures.
5 years ago
OK, here are a couple of shots with the changeable code feature. I'm not sure if you can see it all that well, but the first black ring is an insert that goes inside the second brass ring. You can rotate it to set the "true" notch to any of the letters on the code ring. This also shows the "added security feature" or the "false notches" which make it extrememely difficult to "pick" the lock if the box was tuned poorly enough to allow a person to "feel" where the notches line up on the key by pulling on the end caps and rotating the code rings slowly until you found one that "clicked".

Actually, the ink would disolve on the papyrus roll, yes. And so would the papyrus itself. The end result would be a messy, gross looking goo that used to be the message.

I'm a very picky when it comes to what I like and what I dont like. And this I really like! Good job. Their is two small falts in it. The first about easily being able to decode it. I agree with 'ch5' on what they sayed. The second is I would have like a bit more explanation in how to make it. But thats okay. Im sorry if I seem a bit rude. I hope I hope im not but the only reason Im saying this is because like me some people may not be the smartest crayon in the box sometimes. But other then that Im talking to my dad about letting me make this. I hope to get back to you soon with pictures and any tweaks i may add on the way. ^.^ thanks much!

Okay cool, thanks! Yes I had some questions about it, but when I made this instructable I thought I couldn't explain it better, which is of course hard because in the beginning it can be hard to understand which tube is for what. I would indeed encourage you make faux notches, it was stupid I forgot them! Several people told me about it. I added a line about it in the step too, I believe. But on the other hand, I tried that trick with my cryptex and it wasn't so easy as it seems. With one ring it was easy but the other rings were tight together so I could hardly feel the click. good luck!

Veeery nice :) I like it, and it makes me want to go back to my thrown away blueprints and finally make the one i never had time to finish. Might I suggest a small security improvement tho ? Right now your design seems vulnerable to the basic decoding technique for such locks: If one pulled gently on the opening end while turning the rings one by one, beginning with the most 'binding' one, he'd probably be able to feel it when the corresponding nail falls into the gap , meaning proper alignment. The easy way to defend against such attacks would be to make 26 small notches on the inner rings ( the white ones from step 4 ). One in front of each letter. That way, every step on the rings would provide a small gap for the nail to fall into but without unlocking, which would effectively fool such a decoding :). Excellent work btw.

You can write in other stuff than regular ink, so the "ink" used could be something else than ink, from an alcohol mixed with plant-matter (unlikely) to kohl might be dissolved in vinegar on a papyrus. If Da Vinci indeed invented the cryptex and used vinegar as the dissolvent (wrong term, probably), he probably wouldn't have used any normal ink.
Armchair Pyro4 years ago
It isn't supposed to disolve the ink. The papyrus scroll is supposedly vinegar soluble and is thin enough to do so quickly.

merijnvw (author)  randomness72.54 years ago
See the next step to see the requirements for the sizes. You can choose any sizes just if it is complaint to what I say there. You can of course make your cryptex as big or as small as you want... It's no point for me to write all possible size combinations because those are more than a trillion
where would you find the alphebet strips?

Thanks for the instructable, this is a picture of mine.  The smaller one actually holds more, because the big one's "pegs" stick down into the holding area.

A note to anyone who decides to make one : Take your time and be patient.  When I made my second smaller one I spent much more time on it and liked it much more.

No, I don't study AI, but I am interested in it.  I want to get better at programming so eventually I will be able to make some of my robots have AI (I made a butlerbot with the nxt, that what remote controlled, and I want to "revamp" it with arduino and have and autonomous mode).   Mainly I choose AI for my username, because I liked the way it sounded.

Thanks for posting, it looks good! Only next to the middle ring there is a little gap I can look through.. Did you make faux notches? So someone can't twist and push to the side at the same time, so feeling a little tick when it's on the right place? Then it works even with the small gaps.
Did you think about studying AI?
I program since I was 10 or so, so I am autodidact skilled at normal programming right now, I also do it as a job. But it is different from AI programming, you'll have to re-learn programming for AI. Because you mostly use a language called Prolog, which is totally different from all other programming languages.
I'm also very interested in non-robot AI parts like the semantic web or chat bots.

is it possible that instead of vinegar they could of used hydrocloric acid? they had it back then
4 years ago
This thought occurred to me as well, but I discarded it in favor of more ink. A strong acid would dissolve the message, but if the outer casing should leak, the would be thief could be severely injured, leading to a lawsuit. The law frowns on the creation of objects that can burn people, even if the person being burned is a criminal. There was a thief who was injured falling through a skylight who sued his would be victim and won.

Like... How to make a giant depiction of the Last supper, or How to set up a cryptic expedition? I can't think of anything else. But There are some other ideas from Da Vinci that he never built, I could make one of those. Here are some pages from his diary, not all, and also some other old books you can see in. Page 22 and 23 seem interesting to me, only I don't understand them... Here they summed up some inventions, with screenshots from his diary, and here you can see some aswell. Between those results you can also see something that maybe looks a bit like a cryptex, but it isn't.

Hi,
Going through some old emails and ran across one from you.  So how was the Louvre?  And the hinges?

My daughter went to France, etc. for her French class trip in high school, but that seems like a hundred years ago since she is 30 now.  Maybe I'll get the chance someday, but not too far in the future since I'm 62 already.

Have you posted anymore I*.

Hi Mathman, thanks for the reply.
The trip to Paris had been cancelled because my teacher had a high blood pressure and she was feeling 'a little ill'... yes I know, what a stupid reason to cancel the trip for everyone. And we had to do exams in French there, so now they have to come with a solution.
But visiting the Louvre in one day may not give you a right impression. My teacher has lived in Paris for the greater part of her life and she hasn't seen everything in the Louvre yet, while she has been there over 1000 times(literally, I think because she's an artist aswell)
No, I haven't posted any Instructables yet, that's because I'm in my exam year so I'm very busy with school, posting Instructables is for me something to do during holidays. But you will receive a notification when that will happen, as you are subscribed to me!

A real cryptex also has a mechanism in it the crushes the glass vial of vinegar in case of forced entry. and the vinegar did not make the ink on the papyrus illegible, it destroyed the papyrus, dissolving it.
merijnvw (author)  YellowZealot4 years ago
Then a 'real' cryptex doesn't exist because vinegar doesn't destroy papyrus.

There are a few reasons for that. we get 5% vinegar, because 100% would cost a lot more. and they havent made papyrus for more than 200 years.

i've always wanted to make a cryptex but dont have the skill to make my own.
i can follow instructions but in all of these instructables here the can all be crack by pulling on the end and twisting the wheel. I was thinking and if u made the rings like a car tyre it wouldn't happen... OR does this instructable have a way to stop that above meathod??
merijnvw (author)  fletchy5 years ago
No it hasnt, there were already a lot of comments about this, that suggested to add fake notches that don't go all the way through. That is indeed better but I forgot it. But my cryptex is quite tight, it's hard to feel the notches.

You could also use something like water paint or food coloring to write your message, and use the same fluid in the vial, this would also destroy the message. Also, I have a question for you: How is the vial broken when force is put upon the cryptex?
merijnvw (author)  nieks5 years ago
good idea! Well glass breaks if you bend it only a little bit or if collides fast, so if you take the cryptex and smash it on something or throw it from a building, the glass breaks... And the metal tubes don't. So the cryptex is not yet opened then but the paper gets all drenched in the fluid and make it undreable. That can be done with many fluids like your idea of paint, I will implement that in the introduction if you don't mind, thanks.
5 years ago
No, I don't mind, but I think that there should be a better way to make the glass vial break, maybe something with the point of a nail driven into the glass when it is forced, I'll post a design if I find one that would be sufficient for the job.
Rotten1945 years ago
But the (Dutch) wikipedia also says, that it WILL work if you first drench the paper in saturated bicarbonate. That would make it a fragile kind of paper that would react with the vinegar, making carbondioxide bubbles that will tear apart the paper fibres.
Nope, sorry. Tried it.
The pics are before and after, it was allowed to dry between. It was literally coated with baking soda when I pulled it out, I scrapped it off, dried it, and dunked the paper. It faded the 'n' a bit, but that's all. Pencil and normal pen were no different.

have you ever thought of making on the is spring loaded so that it just pops open? that would be cool
merijnvw (author)  ParaPhrasedProductions5 years ago
Yes I did, but I thought that it would wear out faster because there would be a constant tension on the nails. However if you make the cryptex really smooth so that you need almost no strength to pull it open, you can use a weak spring for it because that wouldn't give much stress on the nails and still pop open the cryptex.
myckro5 years ago
Hi, I started mine today...

merijnvw (author)  Xm3buX5 years ago
Hey cool I got you insterested. I think the Dremel is ok because I believe all Dremels are about the same, yours looks newer than mine so I think it works even better. I don't know if you already have those two things or you are planning to buy them, but the soldering part in this instructable can also be done with an oven, it probably works even better so I recommend trying that. Just look at the instructions at step 3.9. If you are still planning on buying a soldering iron, the one you linked to is good, because it has thin points, so you can well use it for electronics. Mine has a thick plump point which is unhandy.

merijnvw (author)  Einsteins Bro5 years ago
Maybe taking a look at the blueprint could help you understand it. the dials exist of two rings that are glued together, the inner ring is a bit thinner than the outer one, so that there is a space on the inside over the whole ring, where a nail fits in. The outer part of the dial covers the nail so that it isn't visible. in the inner part there is also a notch where the nails go through when all nojtches are lined up correctly. This notch on the inner part isn't visible, because of the outer part.

Actually in the book " Da Vinci Code" it has nothing to do with erasing or muddling the ink. You had to have used papyrus for this any ink would do. The vinigar was used because it would dissolv the " Papyrus" not the ink. Also they were pressed for time and could not freeze the vinigar. for a few reasons. A murdurus albino was after them, a crazy Grail inthusiast was aiming a gun at them and they were wanted by the police. i dont think they had time to freeze vinigar.

actually, in the book it stated that they sued vinegar to turn the papyrus into pulp., so basically you would need the thinnest paper (cigarette paper or tissue paper) and get the vinegar to turn it into pulp. i don't remember where it said it was to mess up the words, but it may be different in the movie. sadly though, the papyrus plant is now extinct, so i have no idea how the author made it possible (it is fiction i guess)

Very nice and well documented Instructable. I have actually been handcrafting Cryptex(R) Security Boxes for over 5 years including ones made with real marble, granite, exotic woods, various polished metals, inlay with precious stones, gold plated, what have you and as far as I have been able to determine, I was the first to actually build such a device (not Leonardo Da Vinci) I have made "Nested" Boxes or a smaller box inside a larger box, boxes with changeable codes and boxes with vials of liquid and papyrus. Here are a few of my creations below.

Those are sum pretty sexy cylinders...

so if one was to purchase one with the cheapest materials (ie mainly wood and such) then how much would one of these cost ?
5 years ago
It would really depend on what specifications, features and design elements you would want. Each of the handcrafted pieces I make are custom commissioned art and the focus is more on the artistic qualities than functionality and they can take several weeks or even months to make so they are not cheap.

But if you are more interested in a very high quality yet loweer cost "replica" version of my boxes which is more geared toward the functionality as opposed to the artistic aspect I have those as well (see attached picture)

But I'd rather not discuss pricing or sales on this forum as it's not really the place for that. If you are interested though you can contact me via my websitehttp://www.cryptex.org and I'll be happy to answer any questions you might have.

Those are really impressive! I have a question, how do you make those rings from marble, brass and granite? With a lathe? I was planning to make a better version of my cryptex, also with changeable codes. And I would like to make it out of a mineral of which you can get big chunks for a not so big prize, like quartz. That's why I wanted to know how you make those rings. thanks!
5 years ago
Yes, I do use lathes for some of the work on my boxes, but the actual techniques I developed for working the stone is proprietary information (sort of "I could tell you, but then I'd have to kill you" kind of things). I know this is an "instructables" website and I'm happy to discuss non-proprietary information or design elements, but I make these boxes for a living and Patent, Copyright and Trademark protections will only get you so far. I've found that the easiest way to protect the techniques and processes I’ve developed over the years is to simply not share the really secret stuff with people (such as how I work the stone). Plus I had to design and create my own tools and techniques for working the stone as this is not something you can simply pick up at the hardware store, so even if I was to tell you how I do it, you’d need to make the necessary tools as well (this would probably cost you a couple thousand dollars). So for most hobbyists this process would be out of reach anyway (but not a corporation, or someone who was willing to invest the necessary capital to do this in the hopes of getting a return on investment by producing and selling these boxes as I do) I have no problem with people like yourself figuring out how to make boxes like the one you did and sharing this with other hobbyists (I actually applaud the accomplishment) but I have to keep certain techniques and processes I use secret to protect my investment in developing these techniques (it took me years and many thousands of dollars to perfect these processes). I don’t mean to sound rude (I’m trying to word this response so you understand where I’m coming from), but I’ve had problems with people in the past taking intellectual property and using it for their own personal gain so I’m a little careful on the subject. I’m sure that you and all of the people on this website are simply hobbyists and would only use this information for personal use or for intellectual curiosity, but there are others out there who would not and the only way to keep this information out of their hands is not to share it with anyone. Sorry, I hope you understand.

frollard5 years ago
Great instructable, This can be easily 'picked' like any rotating lock. To make it more secure, add 4 or 5 false notches on each cylinder, at random locations that do NOT go all the way through. That way someone applying force to open while rotating the dials will get locked up instead of being able to search for the correct letter one at a time. **step 4 picture 1 shows the slots, just create false notches as well**
5 years ago
oop - I see RIAA posted that already... great stuff still!
merijnvw (author)  frollard5 years ago
that's right, still a good idea! But I have tried that method it with mine, I can't really feel the movements when it's on a notch. I have made the outer rings real closely fitting, so that would be hard. And that's also why I rounded the edges at step 4 pic 1, then you won't feel a sudden snap but maybe a slight movement. Do locks from the factory have those false notches?
5 years ago
cheap ones do not, expensive ones have 'all' false notches and 1 real.
5 years ago
My Cryptex(R) Security Boxes all have the "Added Security Feature" with the false/ true notches as you describe. Usually there are 7 "false" notches on each code ring which results in over 35,000 false combinations you would have to manually go through and check IF you could feel where the true notches are... however I tune my boxes really well (single stroke with a fingernail file) so it is next to impossible to feel the notches anyway. I'll post some pictures of this after my next photo shoot.
5 years ago
anyway i explained this mabye in another instructable but if the inised rod with the pegs is on piece then even if one is lined up then the other rings block it preventing movement
5 years ago
I think what frollard was saying was that unless the pegs and rings are tuned absolutely perfectly (something very difficult to do by hand), you can "pick" the lock by pulling on the ends and slowly turning the rings to "feel" when the pin is lined up with the notch on the code ring. You will be able to feel this on the least tuned code ring. Once you find that one, you can repeat the process for the next least tuned code ring and so on until you have found them all. BUT if you put in a series of "false" notches, or notches that go halfway through the code ring, if someone is able to fell when one of these notches (either "true" or "false" notches), once they have been found for all the code rings, you would only be able to pull out the box the depth of the false notch and you would not be able to tell when it is aligned to the true notch. I emply this technique on my boxes and I'll post a picture of this after my next photo shoot.

Hmm, you took a locksmithing course too? Theres a russian lock based on this principal, works the opposite. I cant think of the name, but a German immigrant living in Rus under Catherine the Great developed it from a failed Rus locksmith. Thats the first thing I thought of when you said that...

I aspired to be a locksmith, but extended schooling always turns me away from trades - I'm a jack of all trades...So I just learned how to replace locks, and pick them based on their function. The internet has so much more knowledge than all those courses you can take :) My only problem then is that nobody will hire a non-certified ...

well in medieval times they didnt know about the three states of matter , much less freezers. - Rogue king says " well how can we this meesage out?" knight says " well there was that big white thing with mega freeze written on it ....... we could try that" king says " no no i had it burned for which craft ...it stayed cold inside...it had to have some sort of black magic spell on it ........."

Yes that's why I did research on that but papyrus actually is stronger than our modern office paper! And I read on several pages that it doesn't work with papyrus either, so... I think that's right. However I didn't do a test myself with papyrus, so I can't check it for sure. There don't grow any papyrus plants here in my area.

I've always thought that these were amazing, but I think the vinegar thing wasn't that effective. I would lace it with thermite on the inside and some form of ignitor, so when someone tries to force it open the thermite ignites and causing it to get really hot making the person drop it while anything on the inside burns.
5 years ago
good idea but magniusium or sodium with water capsules would be more effective considering thermites fairly unstable

Thermite is extremely stable, the most reliable fuse is made of magnesium, and it has to bbe ignited with a propane torch.

No you musta heard that about something else. Thermite is very stable, seeing how it's just aluminium dust and iron oxide.

pps well im a bit out of beath hypothetically but u mite want to add a sort of "window" as in a frame around were the selected letters would go instead o the arrows or triangles, this was done n the movie if im not mistaken
merijnvw (author)  shabaki5 years ago
No, that wasn't done in the movie, this is the cryptex that was used in the movie(and that was given to I thought 5.000 people from all over the world who solved a big puzzle by Google, some years ago)
So that one also uses arrows on both sides. I think that looks better because when you would put a frame on the outside, it looks a bit as if that frame holds the cryptex together from the outside, and I don't like those kind of cryptexes. However you can build it if you like that more.

What a fascinating instructable. I think I would have broken the procedures into smaller steps so that there were fewer "sub-steps", but, you make your points very effectively and there's plenty of pictures to help get the message across. And I LIKE your Oyster riddle too, very clever. Thank you very much for sharing your project. It's important to remember that Dan Brown is an author of FICTION, and the cryptex is a plot device. The book is great fun, but it is just a story. There are many reasons that the Cryptex wouldn't work in the way it is used in the book. There is no evidence to suggest that Leonardo devised anything like it, and even if he did, he knew surely knew enough about chemistry to know that the vinegar and papyrus thing is a red herring. If however, you write the message on very fine paper like Cigarette paper, using water soluble ink, and then wrap it around a vial containing water, (or more ink) you would have a device that would serve a similar purpose to the device in the book, and stands a better chance of actually working. Though the cryptex, and the paper wrapped around it would tend to prevent the vial from breaking, you could probably add some kind of "hard point" inside the device to achieve the apropriate breaking force. Or you could use an acidic "invisible ink", vinegar, lemon juice, or any "WATER CLEAR" acid should work, (the less colour obviously, the more successfully invisible your ink will be). Write your message and allow the ink to dry. Roll the paper and place inside the cryptex. When it's time to read the message, remove the paper from the cryptex and simply warm the paper over a light bulb or other very low heat source. This works by causing the acid in the ink to oxidize revealing your message. There are loads of very cool ways to encrypt or disguise a message to go into the cryptex, go forth, investigate, experiment, take care, and have fun.
merijnvw (author)  Dream Dragon5 years ago
Thanks for your reply! So you can also reveal an acidic message with heat? Ok, above I told that you should use a PH indicator for it, but it would be much easier with a light bulb. So I'll add that way. I think I'll use that aswell, if I can find a vial that fits in the cryptex. Maybe I can just use an empty pen exterior, sealed with glue on both sides.
But I'm not sure if L. da Vinci would know that the vinegar thing wouldn't work. The knowledge of chemistry in his time was very low, unlike the other sciences. With chemistry they were still busy trying to turn iron into gold etc.
And for the encrypting thing in the cryptex, I just found a writing system I really like. Here is it. There are also other invented writing systems there, but I like the look of this one, so I'm using it in my cryptex now. And I'm going to use that, my cryptex, and some other things in a puzzle-gift I'm making. It would be doable to reveal what a text in 'graph script' says, if the text is just long enough. Because it's just one letter stands for another, you can use letterfrequence. Each language has an average percentage of frequency for each letter, and you can compare it with those characters, to reveal it. There are some combination characters, like 'sh' etc. But it's still doable I think. Only, then they still have to discover that the text is written from bottom-right to top-left, with vertical sentences.

Chemistry was actually pretty advanced in the medieval and renaisance periods, the time of Leonardo da Vinci. They were trying to do some odd things (like the lead into gold thing) but not because they were bad scientists, they were exploring and testing some pretty outrageous theories. (I gather it is possible to turn gold into lead with a particle accelerator.) Leonardo was no slouch when it came to inks and pigments and paper and such, he'd have known that Papyrus was less susceptible to acid than wood pulp paper, and I'd be pretty surprised if Dan Brown didn't know it too. Yes, A simple "Letter Substitution" code like the "Graph Script" is susceptible to Letter Frequency Analysis, a "Rotating Substitution" like Enigma could be useful, and of course the rings on the Cryptex could act to indicate elemnts of the decryption key. So that instead of simply scrambling the correct combination, the dials could be set to the key word or settings, the correct recipient would note the starting positions of the rings and use that information to aid in the decoding of the subsequent message. In this way, if the Cryptex is tampered with in any way, the key could be lost even if you DO manage to open the thing in the freezer. Combined with a "Word Substitution" code and perhaps a "Plattern Encryption" you could have a very robust system.
shamanwhitewolf5 years ago
For a different AND DANGEROUS method of destroying the message, use brake fluid or similar in the vial and fill the tube with Crystal Draino. I've, um, 'worked' with that combo in the past. When the brake fluid contacts the Draino, it heats up and forms a pile kind of like a carbon sponge. (If you've ever lit one of those little, black disks on the 4th of July that turns into a snake, you've seen what I'm describing.) In my tests, this reaction is sufficient for igniting chemical reactions, so it should either ignite the paper or at least cook it enough to destroy the message. If I get the time, I'll test it and include the results here. Hopefully somebody will get to it sooner (and very, very carefully). KEEP IN MIND, THIS IS FLAMMABLE AND DANGEROUS! ADULTS ONLY! KEEP A FIRE EXTINGUISHER CLOSE! ACTUALLY, YOU SHOULD NEVER DO THIS!
merijnvw (author)  shamanwhitewolf5 years ago
Haha, thanks for the good explanation. However still I don't really understand what those chemical things are, the only thing I understand is that snake disc part.. But maybe other people understand it, they will read it because now in step one I redirect people to these comments like yours, if they want more suggestions on a selfdestruct mechanism. Apparently there are a lot of ways for that selfdestruct mechanism, you all come up with good ideas.
5 years ago
Well, explaining the chemical reaction is a bit beyond me, too. I've long since forgotten my chem skills. However, take a look at the Wiki entry on Drano and how it works. (http://en.wikipedia.org/wiki/Drano) The first bit covers it. After reading that, consider how the Drano would react with flammable hydrocarbons like gasoline or brake fluid.

As a test, find a nice, wide-open place, preferably dirt or paved, not grassy. Place a SMALL pile of Crystal Drano on the ground. The gently dribble a few drops of brake fluid or gasoline onto the Crystal Drano. Done correctly, it will fizzle and swell up like those 4th-of-July carbon-snake things. Done too fast, it might flare up and start a fire. In other words, you either should never do this, or be very, very careful. As in, extremely cautious. If you're going to break the rules of common sense, wear protection (goggles, etc).

If you want to know how hot it gets without doing it (a good idea!), consider that I have used it in the distant past as an igniter for other experiments such as thermite. No matches needed. BE CAREFUL

thefluffball5 years ago
How about a bit of overkill? Hide two vials in there: One with a couple of drops of sulphuric acid, and the other some potassium chlorate. Then all you need to do is write on sugar paper, and if someone smashes it, the whole thing will go up in flames! Or, if your not hiding paper, put table sugar in with the potassium chlorate, or in another vial. It will burn through pretty much anything! WARNING: This creates a lot of flame, and a lot smoke!

merijnvw (author)  thefluffball5 years ago
Haha, cool idea! I have no idea how it works but i'll just tell people to read in the comments to get more ways for chemicals in the cryptex. First I thought it wouldn't be possible but you all come up with these great ideas.
It's been said that DaVinci may not have actually invented a "Cryptex". Though Benjamin Franklin did. He invented a rod with removable wheels (all brass) that had a jumbled alphabet on the edge and labels on their sides so that the wheels could be removed and switched around, and when the recipient received it they could replace the wheels in their proper order, spin the wheels until they spelled out a specific code and elsewhere on the cipher wheels they could read the message. It was ingenious. And I must commend you on the instructable. It's great.
5 years ago
I'm pretty sure that you're thinking of the jefferson wheel, which was invented by Thomas Jefferson, not Franklin. Of course, it differs from a cryptex in that it isn't a lock that contains a note, but rather a code machine. The two do look rather similar, though. How cool would it be to build a cryptex that contained a jefferson wheel...
5 years ago
Ok. Thank you for correcting me. Sorry. I knew it was one of the founding fathers. I simply assumed that it was Benjamin Franklin. And I agree that it would be amazing to combine the two. Or find a way to have changeable passwords. If you keep the same password for too long, it could get cracked, and then opening it would be a synch for anyone who found out. So make it in such a way as to allow you to alter the password once it has been solved. Anyway. Thank you again for the correction. I may have told someone else wrong in the future and then it could spread untill it was told to everyone and we would live in a world of lies, secrets and disbelief!... Oh, wait. We already do. J/K. Have a good day.

Ok interesting, I'll do some research on that Jefferson wheel. Yes I don't know if Da Vinci invented it, I looked through a lot of his diary pages, couldn't find anything that looked in a way like a cryptex, and on cryptex information pages, they often say Da Vinci would have written it in his diary, but nobody ever comes up with that page.

What is the use of the cryptex being four-tubes-thick? -PKT
merijnvw (author)  PKTraceur5 years ago
the dial rings consist of the outer two tubes. you could make them from on thick tube, but that's harder and less effective, because the dials need to be smaller on the inside. That is because there should fit a nail in that place. So my instruction is to make from the second-but largest tube smaller rings with a notch, see step 4 image 1. Then make from the largest tube rings that are bigger and fit into eachother so that they fill the gaps. Then you have two smaller tubes. The dial rings are on the second-but-smallest tube, and you can't get them off it, because there are on both sides of that tube anchor rings, that are nailed to the tube. Then the smallest tube has the nails, and can be pulled out of the second-but smallest tube and the rings, if the password is correct.
5 years ago
Hmm... okay. This is how I understand it. (Ill use three layers... I think?) -The very innermost tube has nails secured into it. They cannot be moved. The InnerDiameter of this contains the "volatile" vial, (vinegar in your Cryptex,) and the message. -The middle layer are multiple "clips" which have a small cut, that can fit the nail, when the clips are aligned correctly, thus creating the password. They move freely, as if on an oiled axi(s) Your Cryptex has 6 CPVC/PVC "clips". -The outer layer is to protect the clip notches from being seen, thus having the password secret. You password is "oyster." The outer layer also has the Alphanumerical "indicator" to allow a set password. Am I correct? I think my explanation is simpler. Thanks

here's an Idea. Making the ink out of vinegar. The only way to find the answer is to use red juice from beats, cherries,or etc. Then you have to heat the paper to see the message. Since the ink is written in vinegar, the vinegar writing will be erased if the glass vile filled with vinegar is broken.

I tried it today. I used vinegar to write the message and used fresh cherry juice to reveal the message. It turns the writing blue and the background pink/purple. The best method for applying the cherry juice is with a Q-Tip. Here is a picture as proof.
merijnvw (author)  cavingboy925 years ago
That's cool! I'll implement it in the Instructable text and film with your name with it! thanks a lot you're the best! If I would be able to give patches I would have given you a cherry master patch. Why actually cherry juice? And how do you know this? Did you just someday think: Oh, lets write with vinegar and then pour cherry juice on it??
merijnvw (author)  merijnvw5 years ago
Okay I put a message in the video and under step 1. I would work even better if you put a lot of salt in the vinegar, because then the freezing point gets so low that it can't be frozen in a normal kitchen freezer, so that the 'freezing method' is also a lot harder, then you need to find a special freezer in a lab or something.
5 years ago
I tried cherry juice multiple times and I did not get the same result.

The best way to reveal the message is with red cabbage because it contains a pigment molecule called flavin. Flavin is also found in plums, grapes, cornflowers, poppies, and apple skins. This option could require people to make a red cabbage solution found at http://chemistry.about.com/library/weekly/aa012803a.htm
merijnvw (author)  cavingboy925 years ago
Ah yes of course it works like a PH indicator! Yes I remember we used red cabbage in chemistry class! But does the ph stay low in the message, I mean, doesn't the vinegar get PH neutral after some time? thanks for you help
5 years ago
I am not sure if the vinegar PH gets neutral after time. I didn't try it yet because I don't have red cabbage. I saw on a website that the message turns dark red because vinegar has a pH of 2.4. With Red cabbage water, Acids turn a Red color, Neutrals a purplish color, and Bases a Greenish-Yellow color.

I thought they said that the vinegar would dissolve PAPYRUS. If any thing, I would use common bleach in the vial and a vegetable base ink.
merijnvw (author)  Aerospaced5 years ago
That's right but papyrus actually is stronger, so it would work better for our modern office paper. Maybe the papyrus is stronger but it's still weaker when it touches vinegar, but I read on several pages that it doesn't work with papyrus anyway. That's also a good idea, would that work? I can put that in the edit: part in step 1 aswell.
Actually, if you read closely in The DaVinci Code, the vinegar isn't meant to dissolve the ink, it's meant to dissolve the extremely thin paper. I believe it's actually a rice paper that was used? But yeah, just wanted to clear that up.

theRIAA5 years ago
ooooohh... can't you just put pressure on the pins and twist each one until it snaps in position? still, GREAT handiwork!
merijnvw (author)  theRIAA5 years ago
No, that isn't possible because the dials fit real tight, and the inner ring of the dial(made from the 3rd tube) has an incision where then with your technique the tab would snap in a little bit, that's one of the two reasons why my instruction is to round the edges of that rings(see step 4 for that) That way you won't feel a sudden snap if there would be one, maybe a real slight movement of the dial to the side, but that would be real hard to feel, because you're turning the dial at the same time.

you could put false grooves in!
merijnvw (author)  theRIAA5 years ago
That's a really good idea! and then form a word with the false grooves, like S-U-C-K-E-R. But probably that person doesn't only get the false grooves, haha. The grooves only shouldn't be a full groove, just a little cavity will work, that's easier to make AND a whole groove would not protect against lockpickers, Because that groove would also lead to opening the cryptex, unlike redgator12 said below. And if you want it even more effective you could make the whole side bumpy, that way, even if the lockpick method would be succesfull normal, would then surely be hopeless. great idea
5 years ago
that's what i meant, a groove on the side, like a little "V" or since your channels are rounded off, make the "V" rounded, so there's no difference.
5 years ago
Like putting in small grooves on like 2 or 3 of the inner rings that actually don't work. Like they do have the groove, but it doesn't follow all the way through so if you tried to pull it out it would get stuck on a small remaining "wall" of wood at the end of the groove. Good idea!!!

Instead of nailing it can it be glued or are the nails used for something else?
merijnvw (author)  corsi5 years ago
As you can see I used glue AND nails on most places, you could leave away the nails, but I don't recommend that, they make the strongest connection, and the cryptex needs to be a able to hold the maximum power of a man's arms, if that person doesn't have the password right but believes he is right, he may keep pulling harder and harder. So these nails are place perpendicular on the pull-direction, that makes a real strong connection, and the glue connection is parallel on the pull-direction, so much weaker. The reason why I use glue is also just that the thing kept in exact the same place when I later inserted nails and screws. And moreover, the nails are really needed at step 1.5 to 1.9. Those nails are the tabs that go through the notches on the dials, and they're soldered from the inside of that tube. Glue won't work for that, it should be solder, OR your tube could be made from real thick PVC so that it holds the nails good aswell. I think nails are the best and easiest solution for that tabs, maybe you could think of something else but I can only think of harder ways.

I'm sure you're right about ink not being dissolved in vinegar, but the key is in fact the carrier for the ink: papyrus is a very fragile material which does not like getting wet at all (Dan Brown, the old hack, had already used this idea in Angels and Demons of course).
merijnvw (author)  kissiltur5 years ago
That's what I first thought too, but then I read somewhere that that If that vinegar thing would work, it would work even better for normal paper, because papyrus actually is stronger. That didn't surprise me because those papyrus rolls from up to about 4000 years from Egypt are still readable, but the 'modern' papers, from the last millenium or so, almost all decay much earlier. And I think the office paper we now use will do that even faster. Wikipedia says only that Papyrus will rot when it's wet, not that it will disolve immediately. And rotting takes so long that the cryptex would be already open. But it may be true what you're saying, that it does work with papyrus. If i know that's true -with a link or a test by myself- I'll add that to the Instructable!
