Thousands of years ago, people changed letters in places and received a cipher. One hundred years ago, people invented Enigma. At the beginning of this century, we got cheap 3D animation. A year ago, I watched foreign videos and read subtitles in my native language. Today I watch foreign videos with instant voiceover in my native language, translated and dubbed by a neural network. What will be tomorrow? And yet in my childhood I translated foreign literature with a dictionary. Thanks to the author from the other side of the planet.

[@schwarzerritter5724]

Enigma would not have been cracked at all had the soldiers known how to properly use it. Enigma was a highly complex version of the Caesar Cipher, but it still had the same weaknesses: -Enigma was used for messages that did not necessarily needed to be encrypted, giving the enemy more data to work with. -'E' is the most common letter in the German language. 'E' will most often be followed by 'R' and 'N'. 'Q' is always followed by 'U'. "Ich" (German for I) is the most common trigram. -It was possible to guess words from context. For example, if a German submarine saw you lay mines, you know the message will contain the word "mine" several times. -German soldiers had a formal way of writing. To use the last example, the message would be pretty much guaranteed to start with "Achtung Minen". Had they knows they needed to try using the letters equally and deliberate make spelling errors, especially in the head of the message, Enigma would have been much harder to crack.

​@@schwarzerritter5724 It could be partially brute forced with the 'Bomb' computers at Bletchley park by the middle of the war, and narrowed down algorithmically using the machine's one mathematical 'flaw' (that a key could never light its OWN lamp, and therefore the patterns of letters in natural language would bleed in in reverse) but, yeah: even by the end never fast enough to do so before the codes changed without luck or human error involved. A lot of code books were stolen meaning the cryptologists could basically take a break for a week and help the other departments with their cyphers, a lot of comms operators were lazy and started their reports with words like 'weather report,' and the nazi army was fairly tolerant of that kind of laziness (though the navy was fairly strict and even introduced new rotors later in the war because they were properly paranoid, unlike the army and air forces, who were confident in Enigma being uncrackable and therefore only made token gestures to crack down on lazy messages to appease the navy).

Back in college, my best friend asked me to assist her on her final project for her cryptography class. While half her class did papers or presentations on crypto-currency, She, myself and another class mate got together and built an eigma machine from scratch. It didn't look anything like the real thing. We used cardboard rotors with fastener pin contacts and a few scattered lego pieces. You had to manually rotate each rotor for every input, the whole thing was a mess of wires and looked like trash. But it worked. We got the cryptography right. The mess of parts that looked more like a middle school art project than an electro-mechanical computer successfully scrambled messages and decoded them. In the end we got an A- on the project because it was only 90% finished, but we proved to the professor we understood the process and mechanics and this was his favorite project of all of them. In hindsight, I wish we had gotten a group photo with the thing.

seems like a pretty fun project for electrical engineering as well, especially with modernized storage settings like on a floppy with a microcontroller that reads those settings. though this would mean that the system (especially the microcontroller that reads the settings) needs to be robust enough (perhaps redundant microcontroller could be installed) so if one shorts out you can have additional ones.

In awe of history of braking this code and work done by Rejewski/Zygalski/Różycki and then Turing it's easy to forget how ingenious this machine is. Mechanically it's not THAT complex yet the path is scrambled so many times seemingly with so many variables and every little change of them changes the output completely.

[@andrechagas4549]

It wasn't clear to me how the machine can be used to decode. Using an specific setting, pressing the letter X will give us C, but pressing C could result in H, not X. So, how to decode? I noticed a black lever at the right side of the machine. I bet this should be used to select if we want to code or decode. And it should change the wiring somehow... But this was not talked about

[@juliuszkocinski7478]

@@andrechagas4549 Look how: 1) Switches work in a way that if the key is pushed it directs flow from source to sipher mechanism and if not - from mechanism to bulb. 2) at every point of scrambling no two letters are changed to one letter. 3) when the flow is presented it goes from pressed key "A" to rotors/reflector/rotors and then back to differend switch (let's say of key "B") only to be directed to bulbs. cables work two ways so if instead "B" was pressed the electricity would take exact same path through cipher mechanism just in different direction. Going back to "A" and then to bulbs. So at each moment 26 letter are organised in 13 distinct pairs so if you press one of these two the other one is lighten up and vice versa. There's no "mode" for coding/decoding. This also explains the weakness of enigma - why no letter can ever be changed to itself.

It is actually work like this I think. Let's only think about the case of three rotors and the reflector. When you press A, it goes through the sequence of A -> B -> C -> D -> E -> F -> G -> H. Here A -> B and G -> H are through the same rotor (the first rotor), but in opposite direction. while on the descriptor's side, if you press H, it will become G after the first rotor (remember the direction), then F after the second rotor, and so on. So it is like going backwards of the encryptor side. Finally it goes through the process of H -> G -> F -> E - > D - > C -> B -> A.

This is the first time I understand at least something clearer about the famous Enigma machine. Congratulations on your work!

[@UDPride]

Great animation. The Enigma was an amazing machine but it had one fatal flaw that allowed the allies to decipher its messages: a letter in the code could never represent itself. Seems like a small thing but the Bombe machine in the UK and Building 26 machines in Dayton used this weakness to run infinite scenarios until it found a set of possible letters not representing themselves that could potentially form a word. They used known German phrases as likely "hits" and when one of those buzz words was found it then ciphered that part of the code. Knowing decrypted letters could never be the same encrypted letters gave them just enough room to rule out complete randomness. There were a couple other weaknesses such as the 2nd and 3rd rotors turning much less often so they could be eliminated to decrypt a lot of the initial parts of German messages since the first rotor was doing most of the work. The additional rotors only came into play on longer messages. It remains one of the most impressive reverse engineering feats of all time without ever having an actual Enigma machine to interrogate.

[@DevSolar]

And it would have been rather simple to remove those flaws. Most importantly, get rid of the reflector. That would have required a different wiring, but would have the removed the flaw of a letter never representing itself. With just a few tweaks (like increasing the number of rotors), the Enigma would still hold up quite well today. A good thing it didn't.

[@Dingsrud]

This setup made the Enigma more compact and practical in use, but also made it possible to crack it. There where other rotor machins around. The signals passed the rotors in one direction from an input side to a corresponding output side. To decrypt you had to swap keyboard and lamps or top turtle the rotor stack.

Brilliant script; genius animation. I knew generally how Enigma worked, but didn't grasp the mechanical complexity. Makes me wonder how electrically reliable it was inside a U-boat with high humidity, corrosion and mechanical jarring from sea conditions. Never much about it being unreliable, but I suspect it was challenging to maintain in the field.

[@nobody7817]

To answer that a bit--we used to take older devices that had mechanical relays at the output, and give them a 2 foot drop test when they started to garble. The jarring affect would knock some of the crud off of the relays. It kept them from garbling the message for a few more weeks--until the replacement relays came in. So... I'm sure the constant jarring helped to keep the contacts somewhat cleaner. It would probably wear them out faster...so they probably had extra wheels on hand. The repair of this device would have been super easy.

And this is if you have a working set of the machine and rotors Cracking these in time for it to be remotely useful is humanly impossible without tools, modern computers can probably just brute-force it, spit out all the possible combinations, and filter out the gibberish to let the user choose from a small selection of highly probable correct answers, but not back then

​@mi1400 Just having an Enigma isn't enough to intercept coded messages. You must have the correct settings as well (which was mentioned in the last segment). With all of the setting variables available (rotor set, rotor order, ring setting, starting position, and plugboard) there were almost 159 quintillion (159,000,000,000,000,000,000) different permutations, only one of which would decrypt the message. These settings would change daily according to a code sheet that was distributed in advance. A code sheet obviously could be captured from a seized ship or platoon, but then new code sheets would be distributed, making the stolen ones useless. Ultimately Alan Turing and his team were able to break Enigma through brute force analysis of how common words were encrypted using a machine called a "bombe" - which could be considered the world's first computer. Watch the movie "The Imitation Game", it'll give you a really good idea of how it happened.

[@elonwhatever]

It becomes easier if you know in advance what a message might say, because then you can work in reverse. If you know there are say 60 characters in a message followed by "heil hitler" you can start looking for the configuration that gives you that. An even bigger weakness is if you know exactly how a message starts. The Germans often opened their messages with "to x". So this kind of nullifies the greatest strength of the code: the self permutation. Note I said easier, not easy. You still have 26 permutations per rotor multiplied by the amount of rotors both in use and not in use (because you do not know which are in use), multiplied by the number of order configurations of the rotors, multiplied by the amount of settings on the plugboard. Now all this assumes you already have an engima machine so you figured out the way the rotors and wiring are configured internally. The way you figure that out is by computing through brute force. Which is what the Bombe was for. Just a giant computer which had as only function running through permutations of the machine until it showed you a message that made sense. What also helped was that the Germans has operational practices that limited the amount of options that has to be tried: Eg. They never left the same rotors in the same position the rest of the month, no letter on the plugboard was allowed to connect to its neighbour, etc. This and other bad/lazy practices of operators further limit options or make finding a correct option easier. Which is what it all boils down to: limiting the problem space.

The first attempts to break the Enigma code were made by the French, the English and Poles as early as the end of the 1920s, but to no avail. French&British doubted that the Enigma encryption could be broken that they basically stopped all attempts, but Polish mathematicians of that era was then among the world's best and they decided not to give up. There is no place here for a description of decryption work, military intelligence actions, etc. all works took many years - but finally just before the outbreak of the war in 1939, the Poles handed over the broken codes and working models of Enigma machines to their allies: the French and the English, one copy each. Shortly thereafter, in Great Britain, at the Bletchley Park decryption center under the leadership of Alan Turing, further work on the Enigma began, based on Polish achievements. Thanks to the work of Polish and later British cryptologists and copies of Enigma intercepted in the meantime, at the end of the war practically all correspondence encrypted with it was read by the Allies in less than two days.

Finally, i found a comment about The Imitation Game, I loved the movie so much . The tragic end of Alan Turing, his failed love life, his hardwork all emotions were presented perfectly in the movie.

@@cetus4449 you are correct the work done by the Poles handed the British a big head start having the knowledge of how the machine worked and encoded and decoded saved valuable time and allowed the focus to be placed on cracking the method in which the Nazis used it. Many contributed to the efforts most have for far too long gone unacknowledged for their efforts.

@@fandangobrandango7864 Apparently you seem to not exactly know history. Poles are quite capable people. Talking about swimming. Do you know the story of Polish submarine ORP "Orzeł" ("Eagle") which after Poland was invaded in 1939 and home port was taken over by the Germans had to find way to escape from Baltic sea somewhere to one of allied countries? They chose England. Do you know story of other Polish warships? Like ORP "Garland"? And some more? Have you ever heard about Squadron 303 in the Battle of England? Do you know why Soviets hesitated, and did not want to openly enter Poland in 1980 - 1981 during massive protests and unrest like they did in 1968 in Czechoslovakia? Do you realise that Poland few hundred years ago relatively briefly was largest European empire? That first Constitution in Europe was the Polish one? Poles can f.... swim.

The Enigma is Ingenious! How they could design and think of such a thing is amazing!

[@breadtoast1036]

the enigma machine and the solution to solving it was an insane feat of human ingenuity and paved the way for modern computers

[@fillflashdetailer8838]

One of the clearest, most well-done teaching videos I've ever seen. Your 3D modeling is extraordinary, making this highly impressive and complex machine come to life.

[@wakeupuk3860]

Yes having many years in education, IT and media content could not agree with more.

I used a KL7 when I was in the US Army, Stationed in Northern Germany in 1976-78. I was always perplexed by how it worked and I wont pretend I understand it now, but your explanation certainly helped me get a little better understanding of how complex and wonderful this machine is/was

[@flyingspirit3549]

Incredibly brilliant description of this complex device that was central to WW2. Thanks for creating this video!

[@Anthony_Stuart]

I almost didn't click this video because I've seen a dozen explanations of the Enigma Machine and I've never been close to getting it, but this video explained it so well I've totally got it now. Very well done

[@JaredOwen]

Thank you Anthony!

[@michelearcangeli509]

I cannot imagine how difficult was to create this amazing video. You are really great!

[@billm6774]

In the late 60's early 70's we in the Army were still using basically the same machine to encode messages. Thanks a good presentation.
