Code licensed MIT. fosskers / enigma Star 3 Code Issues Pull requests An encryption algorithm inspired by the Enigma Machine.The repeated changes of electrical paths through an Enigma scrambler, implemented a polyalphabetic substitution encryption which provided Enigma's high security. The diagram on the right shows how the electrical pathway changes with each key depression, which causes rotation of at least the right hand rotor. Current is passed into the set of rotors, into and back out of the reflector, and out through the rotors again. The greyed-out lines are some other possible paths within each rotor; these are hard-wired from one side of each rotor to the other. Letter A encrypts differently with consecutive key presses, first to G, and then to C. This is because the right hand rotor has stepped, sending the signal on a completely different route; eventually other rotors will also step with a key press. Cipher machine operators were issued with a Key Sheet every month, which told them how to set up their Enigma machines for every day that month. There was an obvious security flaw: if the Allies recovered a key sheet, they would be able to read the Enigma messages.If you put n=10 you will get the 150 milliion million answer. Interestingly, if you put n=11 you get a bigger answer still, but for n=12 and n=13 the number falls. So the Germans missed a trick, they should have used 11 and not 10 cords !

The first breakthrough in the battle to crack Nazi Germany's Enigma code was made not in Bletchley Park but in Warsaw. The debt owed by British wartime codebreakers to their Polish colleagues was acknowledged this week at a quiet gathering of spy chiefs.A unique rotor machine was constructed in 2002 by Netherlands-based Tatjana van Vark. This unusual device was inspired by Enigma but makes use of 40-point rotors, allowing letters, numbers and some punctuation to be used; each rotor contains 509 parts.[41] Template:- Enigma allowed an operator to type in a message, then scramble it by using three to five notched wheels, or rotors, which displayed different letters of the alphabet. The receiver needed to know the exact settings of these rotors in order to reconstitute the coded text. Over the years the basic machine became more complicated as German code experts added plugs with electronic circuits.This vital headstart from the Polish, coupled with the unique problem-solving and intuitive thinking skills of Bletchley's recruits, meant that Enigma was cracked in early 1940 a reliable technique for cracking Enigma was established. The British code breakers worked in shifts around the clock for the whole of the war, using paper and pencil as well as newly invented mechanical techniques to work out the particular Enigma machine settings for each and every single day. An Enigma machine is any of a family of related electro-mechanical rotor machines used for the encryption and decryption of secret messages. The first Enigma was invented by German engineer Arthur Scherbius at the end of World War I. This model and its variants were used commercially from..

But the Enigma code was broken, and the story of the code machine and its eventual decryption is Okay, so in the first video above, Dr. Grime gives us a thorough tour of the Enigma machine (Sir.. Thanks to your groundbreaking work the Allies ( Bletchley Park and other) were able to decode enigma transmissions - well done!Most of the key was kept constant for a set time period, typically a day. However, a different initial rotor position was used for each message, a concept similar to an initialisation vector in modern cryptography. The reason for this is that were a number of messages to be encrypted with identical or near-identical settings, termed in cryptanalysis as being in depth, it would be possible to attack the messages using a statistical procedure such as Friedman's Index of coincidence.[17] The starting position for the rotors was transmitted just before the ciphertext, usually after having been enciphered. The exact method used was termed the indicator procedure. It was design weakness and operator sloppiness in these indicator procedures, that were two of the main reasons that breaking Enigma messages was possible. In the commercial Enigma model C, the reflector could be inserted in one of two different positions. In Model D, the reflector could be set in 26 possible positions, although it did not move during encryption. In the Abwehr Enigma, the reflector stepped during encryption in a manner like the other wheels. Certainly a credit should be given to Polish mathematicians who for the first time worked out the secret of Enigma. These were: Marian Rejewski, Jerzy Rozycki and Henryk Zygalski. In 1932 they already established inner rotors wiring which was probably one of the greatest break trough steps in decrypting messages. The also reconstructed prototype of Enigma itself and designed electromechanical machine called by them "Bomby" to find the keys to daily messages decryptions. Alan Turing did not design first computer. He worked on improved device the "Bomby" which later was further improved by American engineers. Polish Cypher Bureau team gave all the secrets about Enigma machine, the "Bomby" design and other related information to the British crypto-analysts already in July of 1939.

Army issue Enigma machines had three revolving "wheels" or "rotors" that could be taken out and changed about.The first task for an Enigma operator would be to decide which rotor went in which position. There were five rotors to choose from and they could be inserted into three positions on the Enigma machine.One of the key objectives for the Allies during WWII was to find a way to break the code to be able to decrypt German communications. A team of Polish cryptanalysts was the first to break Enigma codes as early as 1932, however the German used more advanced Enigma machines making it virtually impossible to break the Enigma code using traditional methods. In 1939 with the prospect of war, the Poles decided to share their findings with the British. Dilly Knox, one of the former British World War I Codebreakers, set up an Enigma Research Section at Bletchley Park, England. He worked alongside Tony Kendrick, Peter Twinn, Alan Turing and Gordon Welchman. Together they developed a complex machine called the Bomb used to workout Enigma settings from intercepted German communications. The first wartime Enigma messages were broken in January 1940. Being able to decrypt German messages gave the Allies valuable information which has had a major impact on the outcomes of WWII.

Each of 5 rotors may be chosen for the 3 rotor slots. Each rotor creates a permutation of the code. They would have been smart not to have any of the 5 rotor permutations be commlutable with any other, so for choices for first 3 slots one gets (all in agreement with this web site): 5*4*3=5!/2!=60.This logic implies that there would be 26 wires total within all cables and jumper plugs as I wil discuss. (Not 10, not 13--though they could be paired cables for ease of connection in which case there are 13 double wire cables still equivalent to 26 wires just constrained in positions. There could even be 10 paired cables and 6 jumper plugs so 10 pairs swap letters as discussed, and then 6 jumpers mapped to the same letter--but this could also be generalized by 26 individual double-banana cables. Jumping the top row to the same letter's bottom row would map letter to itself.) The specifics could be a convention of how the cables were constructed as paired cables, and 10 paired cables and 6 jumper plugs would fill all positions and swap letters as discussed for exactly 10 pairs. If the "10" was derived from loosing 3 paired wires and there were no jumper plugs around, then the machine would not work! Is the "10" derived from coding sheet?However, the cribs alone were not enough. The codebreakers at Bletchley Park developed new procedures and algorithms for determining the set-up of the Enigma and also had to develop electronic computing devices to implement these methods.

The Enigma machine is an encryption device developed and used in the early- to mid-20th century to protect commercial, diplomatic and military communication Among the most famous of the leading code breakers at Bletchley Park was a mathematician from the University of Cambridge, Alan Turing. Turing was regarded by many as a genius. He played a leading role in breaking the more complicated Naval Enigma cipher (codenamed Shark) and also established the principles behind the modern computer.

Enigma is a german ciphering/deciphering machine. Based on an electromechanic system using rotors, it allowed to cipher german communications during World War II The Wehrmacht and the Luftwaffe transmitted messages in groups of five characters. The Kriegsmarine, using the four rotor Enigma, had four-character groups. Frequently used names or words were to be varied as much as possible. Words like Minensuchboot (minesweeper) could be written as MINENSUCHBOOT, MINBOOT, MMMBOOT or MMM354. To make cryptanalysis harder, more than 250 characters in one message were forbidden. Longer messages were divided into several parts, each using its own message key. For more details see Tony Sale's translations of "General Procedure"[20] and "Officer and Staff procedure".[21]

An Enigma machine is a famous encryption machine used by the Germans during WWII to transmit coded messages. An Enigma machine allows for billions and billions of ways to encode a message.. The effort to break the Enigma was not disclosed until the 1970s. Since then, interest in the Enigma machine has grown considerably and a number of Enigmas are on public display in museums in the U.S. and Europe. The Deutsches Museum in Munich has both the three- and four-rotor German military variants, as well as several older civilian versions. Two Enigma Machines acquired after the capture of Template:Ship during WWII can be seen at the Museum of Science and Industry in Chicago, IL. A pair of functional Enigma machines are on display in the NSA's National Cryptologic Museum at Fort Meade, Maryland, where visitors can try their hand at encrypting messages and deciphering code. The Armémuseum in Stockholm in Sweden had an Enigma on display. The National Signals Museum in Finland has one. There are also examples at the Computer History Museum in the U.S., at Bletchley Park in the United Kingdom, at the Polish Army Museum in Poland, at the Australian War Memorial, and in the foyer of the Defence Signals Directorate, both in Canberra, Australia, as well as a number of other locations in Germany, the U.S., the UK and elsewhere. The now-defunct San Diego "Computer Museum of America" had an Enigma in its collection, which has since been given to the San Diego State University Library. A number are also in private hands. Occasionally, Enigma machines are sold at auction; prices of US$20,000 are not unusual.[37][38] Now plug board: Apparently from pictures they didn't use jumpers blocks, so the plugs must indeed have internal switches so that a position without a plug shorts through from output to input. Each cable enacts a swap, but all the 10 cables are identical. Likewise swapping ends of the cables produces an identical results. 26*25/2 * 24*23/2 * 22*21/2 * ... * 10*9/2 * 8*7/2 / 10! = (26!/6!)/(10!*2^10) = 158.962555217826 million million million ish, call it "159" like in the movie! (PS: Not one scene of The Imitation Game came from the book, not one thing actually happened. Still I think that the decoder wheels bore some vague relationship to the "bombs" construction and is useful for thought. Successive columns would be successive input/rotor positions, and rows correspond to rotors all tree searched. Needs more for searching the plugboard settings than was shown in the movie. At least I'm making some progress in understanding this now.)First, how could some of the jacks remain unconnected? If they remained unconnected, then their output side would go nowhere! It would not be left as its own code, it woud produce no code at all! Those banana jacks were not like our complex headphone jacks that have an inner switch--this is very simple hardware, appears to be nothing more than a plugboard of simple banana jacks in pairs.

Information about Enigma Machines came in two forms: how they machine looked, and how it actually worked. Fortunately, there are a lot of helpful pictures of every part of the machines available online.. To avoid merely implementing a simple (and easily breakable) substitution cipher, every key press caused one or more rotors to step before the electrical connections were made, and so changed the substitution alphabet used for encryption. This ensured that the cryptographic substitution would be different at each new rotor position, producing a more formidable polyalphabetic substitution cipher. diegodc / enigma-machine Star 1 Code Issues Pull requests Implementation of the Enigma ciphering machine in Java.

Part is just mechanics, many industrial robots work without any "artificial intelligence" (AI) like programming. But others distinctly combine AI (which can be independent of any robotic mechanism) and the mechanisms, such as visual analylsis for feedback. These are all of course based upon the development of the general purpose computing devices--for which Turing did make significant early contributions. In later years those developing ideas for computers and Turing differed on approaches and computer developers ignored turing's later ideas, but they certainly were part of the original foundations. Note that although the ring settings (ringstellung) were a required part of the setup, they did not actually affect the message encryption because the rotors were positioned independently of the rings. The ring settings were only necessary to determine the initial rotor position based on the message setting which was transmitted at the beginning of a message, as described in the "Indicators" section, below. Once the receiver had set to his rotors to the indicated positions, the ring settings no longer played any role in the encryption.

  1. The weakness in this indicator scheme came from two factors. First, use of a global ground setting—this was later changed so the operator selected his initial position to encrypt the indicator, and sent the initial position in the clear. The second problem was the repetition of the indicator, which was a serious security flaw. The message setting was encoded twice, resulting in a relation between first and fourth, second and fifth, and third and sixth character. This security problem enabled the Polish Cipher Bureau to break into the pre-war Enigma system as early as 1932. However, from 1940 on, the Germans changed the procedures to increase the security.
  2. By itself, a rotor will perform only a very simple type of encryption — a simple substitution cipher. For example, the pin corresponding to the letter E might be wired to the contact for letter T on the opposite face, and so on. The Enigma's complexity, and cryptographic security, came from using several rotors in series (usually three or four) and the regular stepping movement of the rotors, thus implementing a poly-alphabetic substitution cipher.
  3. You can't just say 6 * 5 * 4 * 3, because that would consider "wire 1 connects A to B / wire 2 connects C to D" and "wire 1 connects C to D / wire 2 connects A to B" as distinct choices while they are actually the same.

Britain and her allies first understood the problems posed by this machine in 1931, when Hans Thilo Schmidt, a German spy, allowed his French spymasters to photograph stolen Enigma operating manuals. Initially, however, neither French nor British cryptanalysts could make headway in breaking the Enigma cipher.We all know that the English invented everything but I read years ago that the Enigma code was first broken by a Polish person who passed it on to French intelligence who in turn passed it on to the English.

The earliest Enigma machines were commercial models dating from the early 1920s. Starting in the mid-1920s, the various branches of the German military began to use Enigma, making a number of changes in order to increase its security. In addition, a number of other nations either adopted or adapted the Enigma design for their own cipher machines.

In December 1932, the Polish Cipher Bureau began breaking Germany's Enigma ciphers. Five weeks before the outbreak of World War II, on 25 July 1939, in Warsaw, the Polish Cipher Bureau gave Enigma-decryption techniques and equipment to French and British military intelligence.[3][4] During the war, allied codebreakers were able to decrypt a vast number of messages that had been enciphered using the Enigma. The intelligence gleaned from this source, codenamed "Ultra" by the British, was a substantial aid to the Allied war effort.[5] An Enigma machine was any of a family of related electro-mechanical rotor cipher machines used in the twentieth century for enciphering and deciphering secret messages. Enigma was invented by the German engineer Arthur Scherbius at the end of World War I. Early models were used commercially.. The machine (of which a number of varying types were produced) resembled a typewriter. Enigma traffic continued to be broken routinely at Bletchley Park for the remainder of the war

Also note that there are actually more possible plug board settings because the code sheets can indicate that a cable is not used, so one actually has 10 cables, 9 cables, 8 cables, etc. They probably would not go too far down.Top mathematicians and general problem-solvers were recruited and a bank of early computers, known as 'bombes', was built to work out the Enigma’s vast number of settings.Simon Greenish, director of Bletchley Park, describes the role that the Bletchley Park code-breakers played in changing the course of the war. The Enigma machine's place in history was secured in 1924 when the German armed forces began using a specially adapted military version to encrypt their communications. They continued to rely on the machine throughout the Second World War, believing it to be absolutely unbreakable.Since a letter can only be plugged into 1 other letter, that leaves 24 letters to choose from for the next cord.

By 15 July 1928,[29] the German Army (Reichswehr) had introduced their own version of the Enigma—the Enigma G, revised to the Enigma I by June 1930.[30] Enigma I is also known as the Wehrmacht, or "Services" Enigma, and was used extensively by the German military services and other government organisations (such as the railways[31]), both before and during World War II. The major difference between Enigma I and commercial Enigma models was the addition of a plugboard to swap pairs of letters, greatly increasing the cryptographic strength of the machine. Other differences included the use of a fixed reflector, and the relocation of the stepping notches from the rotor body to the movable letter rings.[30] The machine measured 28×34×15 cm (11 in×13.5 in×6 in) and weighed around Template:Convert.[25] emulator cli enigma enigma-simulator enigma-machine enigma-cipher. rust cryptanalysis enigma enigma-machine The plugboard (Steckerbrett in German) permitted variable wiring that could be reconfigured by the operator (visible on the front panel of Figure 1; some of the patch cords can be seen in the lid). It was introduced on German Army versions in 1930, and was soon adopted by the Navy as well. The plugboard contributed a great deal to the strength of the machine's encryption: more than an extra rotor would have done. Enigma without a plugboard (known as unsteckered Enigma) can be solved relatively straightforwardly using hand methods; these techniques are generally defeated by the addition of a plugboard, and Allied cryptanalysts resorted to special machines to solve it. As technology increases, so do the methods of encryption and decryption we have at our disposal. World War II saw wide use of various codes from.. These lapses provided the codebreakers with clues, called cribs, about how the Enigma machines had been set up on that day. These cribs were essential for breaking the ciphers. For example, without a crib it would still take several months today to decipher an A4 page of ciphertext using a modern PC with trial and error methods.

In order to preserve British security, the breaking of Enigma remained a tightly guarded secret for the duration of the war, and for the following 30 years. The people who had worked at Bletchley Park were forbidden from talking about what they had done and as a result their contribution to the war effort was entirely forgotten. However, over the past 30 years more and more information has been released about the incredible story of Bletchley Park.

  4. A cable placed onto the plugboard connected letters up in pairs; for example, E and Q might be a steckered pair. The effect was to swap those letters before and after the main rotor scrambling unit. For example, when an operator presses E, the signal was diverted to Q before entering the rotors. Several such steckered pairs, up to 13, might be used at one time. However, normally only 10 pairs were used at any one time.
  5. In German military usage, communications were divided up into a number of different networks, all using different settings for their Enigma machines. These communication nets were termed keys at Bletchley Park, and were assigned code names, such as Red, Chaffinch, and Shark. Each unit operating on a network was assigned a settings list for its Enigma for a period of time. For a message to be correctly encrypted and decrypted, both sender and receiver had to set up their Enigma in the same way; the rotor selection and order, the starting position and the plugboard connections must be identical. All these settings (together the key in modern terms) must have been established beforehand, and were distributed in codebooks.

When the Enigma machine is used, the Enigma machine itself is the algorithm; the way in which it is set up is the key. Just as with any other type of cipher, as long as the recipient knows the key, the process of deciphering an Enigma encrypted message is incredibly simple. A German soldier receiving an enciphered message simply had to type the ciphertext letters into his own Enigma machine. If his machine was set up exactly in exactly the same way as the message sender's, then the plaintext letters would appear on the lamp board. Enigma (machine) facts for kids. Kids Encyclopedia Facts. The Enigma machine was created for Germany by Arthur Scherbius in World War I. It is a cypher machine: a way of changing the letters of a message so that it appears to be scrambled letters (or, random letters) In the German Army and Air Force Enigma, the reflector was fixed and did not rotate; there were four versions.

A third version, Umkehrwalze C was used briefly in 1940, possibly by mistake, and was solved by Hut 6.[15] The fourth version, first observed on 2 January 1944, had a rewireable reflector, called Umkehrwalze D, allowing the Enigma operator to alter the connections as part of the key settings. emedvedev / enigma Star 35 Code Issues Pull requests Enigma cipher machine emulator (CLI + library) written in Go In the Enigma Machine lesson, students will learn the intricacies of cryptography used in World War II to Students will then learn about the German Enigma Machine and will run a web-based emulated..

Enigma - the German military cypher machine, and the efforts to break

An Enigma machine is a electro-mechanical rotor cipher machines used for the encryption and decryption of secret massages. Some History (1). Slideshow 2315572 by oleg Current flowed from the keyboard through the plugboard, and proceeded to the entry-rotor or Eintrittswalze. Each letter on the plugboard had two jacks. Inserting a plug disconnected the upper jack (from the keyboard) and the lower jack (to the entry-rotor) of that letter. The plug at the other end of the crosswired cable was inserted into another letter's jacks, thus switching the connections of the two letters.

In December 1938, the Army issued two extra rotors so that the three rotors were chosen from a set of five.[30] In 1938, the Navy added two more rotors, and then another in 1939 to allow a choice of three rotors from a set of eight.[34] In August 1935, the Air Force also introduced the Wehrmacht Enigma for their communications.[30] A four-rotor Enigma was introduced by the Navy for U-boat traffic on 1 February 1942, called M4 (the network was known as "Triton", or "Shark" to the Allies). The extra rotor was fitted in the same space by splitting the reflector into a combination of a thin reflector and a thin fourth rotor.

As long ago as the Ancient Greeks, warring armies have encrypted their communications in an attempt to keep their battle plans a secret from their enemies. However, just as one side invented an ingenious new way to encipher its messages, so would its enemies discover a clever way of cracking that code. The result has been that codes and ciphers have become more and more complex and increasingly difficult to crack over time, as, throughout history, an intellectual battle has raged between code makers and code breakers.

Fiona Bruce talks to Jean Valentine, a Wren who worked as a code-breaker at Bletchley Park during the war. Up till the Second World War, the most advanced forms of encryption involved simple paper and pencil techniques. But security blunders on both sides during the First World War highlighted a need for a higher level of secrecy, with more advanced methods of enciphering messages. Both the Allies and the Axis countries were looking for a new way to encrypt messages - a way that would result in complete security. (For more information, have a look at our explanation of the basic terminology of codes and ciphers.)This might even make sense. The 6 jumper plugs used so that not all letters are remapped, thus NOT allowing codebreaking to assume no letter maps to itself. 10 paired cables to ease the operator connection method. (All reduced from the possability of any permutation mapping of 26 letters if 26 individual cables were provided.) 13 paired cables and no jumper cables would assure no character maps to itself, but allows any letter to be swapped with another and the next swap reduced by 2 recursively until all letters mapped.

Download Enigma machine stock photos at the best stock photography agency with millions of premium high quality, royalty-free stock photos, images and pictures at reasonable prices When placed in an Enigma, each rotor can be set to one of 26 possible positions. When inserted, it can be turned by hand using the grooved finger-wheel which protrudes from the internal Enigma cover when closed. So that the operator can know the rotor's position, each had an alphabet tyre (or letter ring) attached to the outside of the rotor disk, with 26 characters (typically letters); one of these could be seen through the window, thus indicating the rotational position of the rotor. In early Enigma models, the alphabet ring was fixed to the rotor disk. An improvement introduced in later variants was the ability to adjust the alphabet ring relative to the rotor disk. The position of the ring was known as the Ringstellung ("ring setting"), and was a part of the initial setting of an Enigma prior to an operating session. In modern terms it was a part of the session key. EnigmaWarsaw is an outdoor city game in Warsaw organised by StayPoland travel agency.

Check out our enigma machine selection for the very best in unique or custom, handmade pieces from our puzzles shops To illustrate the detailed operation of Enigma, please refer to the wiring diagram to the left. To simplify the example, only four components of a complete Enigma machine are shown. In reality, there are 26 lamps and keys, several plugs (varied with model) and rotor wirings inside the rotors (at least three were installed). Current flowed from the battery (1) through a depressed bi-directional letter-switch (2) to the plugboard (3). The plugboard allows rewiring of some letter connections between the keyboard (2) and the fixed entry wheel (4). Next, the current wends through the (unused in this instance, so shown closed) plug (3) via the entry wheel (4) through the wiring of the three (Wehrmacht Enigma) or four (Kriegsmarine M4 and Abwehr variants) installed rotors (5), and enters the reflector (6). The reflector returns the current, via an entirely different path, through the rotors (5) and entry wheel (4), proceeding through plug 'S' connected with a cable (8) to plug 'D', and another bi-directional switch (9) to light the appropriate lamp.[11]

One of the earliest indicator procedures was used by Polish cryptanalysts to make the initial breaks into the Enigma. The procedure was for the operator to set up his machine in accordance with his settings list, which included a global initial position for the rotors (Grundstellung, meaning ground setting), AOH, perhaps. The operator turned his rotors until AOH was visible through the rotor windows. At that point, the operator chose his own, arbitrary, starting position for that particular message. An operator might select EIN, and these became the message settings for that encryption session. The operator then typed EIN into the machine, twice, to allow for detection of transmission errors. The results were an encrypted indicator—the EIN typed twice might turn into XHTLOA, which would be transmitted along with the message. Finally, the operator then spun the rotors to his message settings, EIN in this example, and typed the plaintext of the message. The Germans believed the strength of the Enigma lay in the fact that it was impossible to work out the key from the billions and billions of potential keys every single day. As long as the Allies did not get hold of the key sheet, their communications would remain secure.

In August 1939 the British established the Government Code and Cipher School at Bletchley Park in Buckinghamshire. The people recruited to work there came from a variety of backgrounds. There were experienced codebreakers, secret service officers, mathematicians, scientists, crossword experts, international chess players, students, actresses and even astrologers and debutants.The Navy was the first branch of the German military to adopt Enigma. This version, named Funkschlüssel C ("Radio cipher C"), had been put into production by 1925 and was introduced into service in 1926.[23] The keyboard and lampboard contained 29 letters—A-Z, Ä, Ö and Ü—which were arranged alphabetically, as opposed to the QWERTZU ordering.[24] The rotors had 28 contacts, with the letter X wired to bypass the rotors unencrypted.[25] Three rotors were chosen from a set of five[26] and the reflector could be inserted in one of four different positions, denoted α, β, γ and δ.[27] The machine was revised slightly in July 1933.[28] The Enigma machine was an advanced electro-mechanical cipher machine developed in Germany after World War 1. The Enigma machine was used by all branches of the German military as their..

ENIGMA: Something hard to understand or explain. Derived from the Latin ænigma, meaning A machine which has successfully infiltrated every institution and system of our modern world, seeking.. If this were all the Enigma machine did, rotor one would step 26 times for every step of rotor two and rotor two 26 times for every step of rotor three. However, the design also included a feature known as double-stepping. This was enabled due to each pawl being aligned with both the ratchet of its rotor and the rotating notched ring of the neighbouring rotor. If a pawl was allowed to engage with a ratchet through alignment with a notch, as it moved forward it would push against both the ratchet and the notch, advancing both rotors at the same time. In a three-rotor machine the double-stepping would affect rotor two only. This, if in moving forward allowed the ratchet of rotor three to be engaged, would move again on the subsequent keystroke, thus resulting in two consecutive steps. Rotor two also pushes rotor one forward after 26 of its steps, but as rotor one moves forward with every keystroke anyway, there is no double-stepping.[13] This double stepping caused the rotors to deviate from odometer-style regular motion. So you might think that the total number of possible ways to configure 2 cords would be 26*25*24*23/(2*2) but that is wrong. This is because it doesn't matter what order you put those two leads in. This is of fundamental importance in maths, and is the difference between a permutation and a combination. During the heart of World War II, in March of 1943, cryptoanalysts at Britain's code-breaking center have discovered to their horror that Nazi U-boats have changed their Enigma Code
