[@SkyPrinceR]

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.

What an amazingly well-done explanation of something that is rather complex. I now understand why it was such a hard code to crack. Keep up the great work!!

[@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).

Piden diezmos, se creen levitas, entonces debería de haber dos tipos de sacerdocio levita en general que recibían el diezmo (Num. 8:24-26) y deberían de dar el diezmo del diezmo a los sumos sacerdotes (Num. 18:26) y los levitas sumo sacerdote descendiente de Aarón. El diezmo era para el huertano la viuda el desamparado para el extranjero (Deut. 14:22-29). Ya no hay diezmo, pero ellos piden a diaria, semanal mensual, los diezmos eran cada año y otro cada tres años todo eso pertenecía a la ley dada a los judíos. Ellos declaran con su boca entonces ya no necesitan a Cristo, si todo ellos en su error todo pueden con su boca entonces están endiosándose, tremenda mentira, Cristo nos enseñó que dijéramos: si Dios lo permite are el uno u otra cosa. Idolatran a Israel terrenal (anticristos), lo llaman el pueblo de Dios y a los que creen en CRISTO los llaman gentiles (apartado de Dios olvidados de Dios) la escritura dice quien rechaza a CRISTO está condenado (Juan 3:18) y el que acepta a CRISTO JESÚS ya es salvo para vida eterna. Entonces a quien le creo a CRISTO JESÚS o a religiosos mentirosos llamados pentecostales. El pueblo de Dios son los Cristianos que recibieron título de ser llamados hijos de Dios.. Desconocen que los verdaderos judíos son los remanentes hijos de Dios es decir los Cristianos del mundo, el pueblo de Dios, somos los Cristianos. Los mentirosos dicen que para los Cristianos no hay tribulación, no saben cómo vivieron los primeros Cristianos, en roma en Israel, perseguidos, asesinados, quemados, acontecimientos en el coliseo romano, el incendio de roma, persecuciones, por judíos claro ejemplo Saulo perseguidor autorizado por gobierno judíos, inquisición etc etc, y que según esos mentirosos ellos serán raptados en secreto sin que nadie lo sepa y para ellos no hay sufrimiento engañan diciendo son hijo de dios rico y anhelan riquezas y poder terrenal. Dios nada hace en secreto ni se esconde de nadie, todo lo hace avisando miles de años antes y a ojo de todos. Ellos no predican a CRISTO JESÚS, ellos predican a la mentira que no existe (jeova, yave , buda, ala etc.etc. etc) todo el que rechaza a CRISTO JESÚS entonces el tal es bestia (anticristo) Obligan vacunarse. Hablan lenguas que nadie les entiende. Por sus obras los conocerás dice nuestro señor Dios y salvador CRISTO JESÚS. Soy Cristiano hijo de CRISTO JESÚS mi Dios y salvador regresara pronto en las nubes del cielo y todo ojo lo verá ahí mandara recogernos a sus Ángeles con voz de trompeta nos reuniremos su iglesia (todos los Cristianos verdaderos del mundo) CRISTO es la cabeza de la iglesia, ahí las bodas del cordero. Antes de destruir esta tierra y este cielo reinará mil años este planeta, pero antes encarcela por mil años a satanás. Al falso profeta (religiones) y a la bestia (espíritus inmundos seguidores de satanás, google, Facebook, ciencia usada para el mal) serán lanzados al infierno vivos. Después de los mil años satanás es soltado de su prisión no se arrepiente y es lanzado al infierno la candela que no se apaga ni su gusano muere, desaparece este mundo y este cielo inmundo por causa del pecado, nada inmundo prevalece, ahora Dios todo lo hace nuevo, nuevo cielo y nueva tierra, Dios Reyna para siempre.

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.

@@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.

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.

[@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.

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.

He exploited this, and created `bombes` which could be used to decipher an enigma message.

When I joined the Navy in late nineties, I helped install some exhibits in a museum that was being built in Pensacola, and the Enigma was one of them. To hold it in my hands, and to be fortunate enough to already know the history behind it, was something that I will never forget. To have the ability actually touch and examine a piece of history like that was so mind-blowing to me, and I knew even then how fortunate I was to have that rare opportunity.

[@Mark3ABE]

The simplest and most effective code is a simple “book code”. Here, the sender and receiver both have the same edition of the same book. An obscure book was usually chosen. Then, starting at the beginning of the book, each letter is the guide to altering the letter which it is intended to send. If the letter is “d” then the letter to be sent is advance in the alphabet by four letters. The next letter to be encrypted is advanced in the same way - if the next letter in the book is “a” then it is advanced by one letter. Since every exchange of letter is different throughout the message, there is no way of trying to guess what the original letter might have been. Word breaks are a point of weakness, since the word “the” will be common, so any three letter word is likely to be “the”. Similarly, a single letter is likely to be “a”. However, this problem can be avoided by breaking the message up into four letter units. The decoder can then insert the necessary word breaks. Of course, these days, with huge computers, it would be possible to enter the texts of every book ever published and simply run the message against every book until it eventually makes sense.

[@avcomth]

Another thing that blows my mind away when I saw the movie "The Imitation Game" was how it was important that the allies responded to the decrypted messages with statistically calculated winnings and losings in the battlefields---only choosing to act boldly on major engagements and pretended to lose in less significant ones---so that the Germans wouldn't figure out that their machines had been compromised. That is some higher level intelligence derived from maths and sciences.

[@cetus4449]

Remember who broke the code just before the war: Three mathematicians, Polish officers: Marian Rejewski, Henryk Zygalski, Jerzy Różycki. Breaking Enigma was a joint effort of the Allies, but still the public, filled with Hollywood biased movies, ignores the decisive contribution of specialists from Poland. 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.

​@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 enigma machine is an amazing piece of engineering, especially considering the time that it was invented. However, to crack the code was also a great achievement. So many great minds of the time

Gran trabajo! Probablemente sea la mejor explicación audiovisual que existe sobre ésta máquina en todo el mundo. Y gracias por la traducción. No me extraña que los británicos se volvieran locos para intentar descifrar a Enigma, y hay que reconocer el gran talento del ingeniero que diseñara esta maravilla. Sencillamente esta ha sido la cosa más interesante que he aprendido hoy.

No wonder why it was so hard to crack the codes, there were so many details that needed to be just right every step of the way. The rotor layout, starting position, and then the plugboard configuration. Truly an encryption marvel for it's time.

[@ZenoDLC]

Let's see, it's... 5*26*4*26*3*26 on the rotors alone, 26! for each connection on the plugboard, 26 more for the possibility of each hole not being connected, then you have to match the date so add 365 more possibilities to that... 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

it was actually quite simple: the germans always used a set format when sending messages - position - weather - message - heil hitler. once you know that, then the rest is easy. oh. and getting their hands on the machine and a passbook really helped.

Я вижу одну большую проблему: пусть зашифрованный текст передаётся азбукой Морзе. Если оператор на принимающей стороне, по ошибке, нажмёт хотя бы на одну букву короче или на одну букву длиннее, т.е. если зашифрованный текст введется с "ошибочной" длиной, все эти колёсики и коды будут сдвинуты без всякой возможности "вернуться обратно". Единственный путь будет только установить все колёсики до их первоначального состояния "по бумажке". В этом случае, сообщение должно быть повторено полностью. Это значит что канал передачи должен быть так же идеален с точки зрения "шума".

[@СергейАликперов]

@Alex-Grek всё правильно : сначала приём на слух на бумагу , так морзянка и принимается до сих пор , а потом ввод в машинку. 60-80 знаков в минуту.

[@Борис-н2н1я]

@Alex-Grek При СССР в армии была такого же типа только 10 дисков со вставками , 56 шариков и код на каждый день в спец блокнотах. Для каждого позывного свой . И блокнот общей связи.Информация шла как на перфоленте так и морзянкой . Печатали от 4 до 6 знаков в секунду и три ошибки по печатному тексту на 11 формате, для того чтобы сдать на Первый класс специалиста. Если сдавали на Мастера то 7-8 нажатий в секунду и ни одной ошибки на 11 формат печатного текста. Но это уже давно устаревший вариант механической кодировочной машины . Тогда криптостойкость сообщения , при тех ЭВМ , составляла 150 лет.( со слов преподавателей в учебке).

Enigma is truly one of the great engineering marvels. Ridiculously complicated codes from an extremely compact design, man portable and with such a complicated and convoluted, easily changed pattern that a human wouldn't be able to detect the pattern. It's extremely well made.

[@DerSolinski]

14:57 This was also Enigmas downfall, since it could never be the same letter that was pressed that could light up. That simple fact allowed brute force decryption later on. The Germans knew about that, but didn't thought it would be necessary to make a fix since brute forcing seemed like a undoable task at the time. Nice video btw. 👍

[@dracentral]

Question - if suppose K is pressed, and if the encrypted result is also K, then how will the bulb glow, because circuit contacter is not touching so circuit is not complete. What will happen then, will it be a null output? Can anyone please clear this?

[@DerSolinski]

@@dracentral That's the thing, the fix is "easy" conceptual but it would require a substantial rework of the electro mechanics. As originally build it is not possibile.

[@DerSolinski]

Imagine a wheel with 26 positions for the alphabet. All that the enigma does is add or substract positions ergo rotating the wheel clock wise or counter clockwise. But it was not possibile to add a "0". It always had to be at least 1 position difference regardless of direction. This is the reflectors fault, if instead you would go directly to the lamps/keys (you would need to be able to inverse the path between those to make decryption possible) you don't have that problem. The Enigma would have been impossible to crack *reliable* during WWII. The reason why it was "relatively easy" to crack later in the war was because of Allan Turings computer and that the Germans send a lot of stuff in the same format e.g. the weather report, that had known words or rather phrases that made it easy to shoot out a lot of "possible cyphers" that had the same letter and the same place as the in plain text/phrase. With this method and a bit (or lot) of luck you could crack it in a matter of hours or minutes instead of days or weeks.

@@DerSolinski *Tommy Flowers' computer. Electrical engineer Tommy Flowers built colossus WITH HIS OWN MONEY (and some from the telephone exchange dept of the post office) after his military bosses told him vacuum tubes would be too unreliable (he pointed out that they always blew when switched on, like an incandescent lightbulb, so maintenance would be easy provided you didn't switch it off too often.) If they'd done it with relays like the military bosses wanted it would have been too slow. Turing and Flowers got on but they had to deal with some short sighted idiots.

The best explanation of the Enigma machine ever! I have been trying to understand the Enigma machine for years and years. This is the only description I have seen that explains it clearly without throwing about a bunch of jargon and the mandatory "The Enigma had leventeen kajillion dillion combinations!" or some such dramatic figures while skipping over the basic structure. The 3d graphics were absolutely great!
