    Please note that this machine isn't very comlpicated and it uses real wires with great connection unlike the PCBs we have now. PCBs are really easy to damage. I'm not surprised that this can survive this long. Computers would last much longer if they were built like this, but they would be too big and inefficient. The only thing in that machine that needed to be replaced or charged was the battery because we didn't have and still don't perpetual motion machines.

    That Polish Mathematician was Marian Rejewski, he acted as a spy for a couple years, hid from the Nazi Party, broke the Enigma Machine and after all that lost some of his best Mathematician friends who were trying to escape the war. He is truly an un-song hero, and without him, I am certain we would have lost the war. The more remarkable thing is that there was multiple versions of the enigma machine throughout the war, and Marian and his colleagues broke them all.

Navajo indian language is said to be the most complicated in the planet, more than chinese or Inuit. Its impossible to learn and the only way to know it is by learning it from birth from your parents. Each american division would take a navajo indian with them and they would speak with each other by radio, each translating into english the navajo radio calls. The japanese and the germans were never able to decipher the language. In the navajo language there are 160 ways to describe "little" or "small" just to give you an example how complicated it is.

    It actually got even more complex than that, because it was possible to open up the rotors and rewire them, or to simply twist each side of the rotor by a few turns (so pin 1 on the let would match up to pin 3 on the right, for example), so if they ever worked out that we had an enigma machine and were regularly getting our hands on the code sheets, they could just start to rewire all of the machines, making ours useless for a while.

    Breaking the Enigma Machine was a government-held secret. No one except the british secret services knew the code was broken. So for the british autorities, Mr. Turing was a simple military mathematician who was homosexual, and at that time, it was illegal. At least there was an official public apology towards Alan Turing in 2009 and in 2013, the Queen granted him with a posthumous pardon. Only sad thing is he wasn't alive anymore

    The Poles originally broke the basic German Enigma code in 1933. In 1939 they handed their mathematical formulae to the Brits who realized its importance to them -- should they go to war with Germany. Breaking the CODE was NOT or EVER the PROBLEM . The problem was BREAKING IT FAST ENOUGH so that the information contained within the message would be of some use. All that changed with the arrival of Dr Alan Turing -- who managed to develop a MECHANICAL COMPUTER which speeded up the decryption process to within about 30 - 40 minutes. Turing was worth his weight in GOLD to the Brits. The only reason these hypocrites acknowledged his huge value was because of MODERN DAY PUBLIC OPINIUON and the people who WORKED AT BLETCHLEY PARK ---- OPENLY SPEAKING OUT. Otherwise Dr Turing & his superb contribution would have been conveniently forgotten. A bit like Diana -- Princess of Wales & the attitude of the ROYALS towards her. A typical case of BRITISH HYPOCRISY.

    Colm Rooney This is not how it works. You would crash world's economy either way. If you were to share it and to have everyone get the same amount of money, nobody wouldve been poor nor rich. There would be so much money that they would've just become useless. You've seen those pictures of germany after ww1? Their cash was worth, basically, nothing. They used to throw it in the furnace just to warm their house. A slice of bread costed about 2 carts of cash. So, what would happen is that people would drop money as they're not worth anything anymore, they would be worth less than paper that they're made of. People would just go back to the stone age where, the only way you could get grasp of food or items you didn't make yourself was to exchange those items for something equally valuable. As I said, a lot of people, such as lawyers or youtubers, the ones that basically don't make something physical, would die.

    Chaosligend This is not how it works either. You have to take in account the fact that there are guys who "prints" the money by just pressing a button and the rest has to work (physically or intelectually) to get some. And nowdays you dont even need coinage or money printing to create money - you got numbers inside computers. So money only represents value as long as people do believes it. Only 10% of all amount of money on the world has something to do with real economy - the rest is a sort of whip in modern slavery. Remember Gaddafi's doubt about US$ real value? We all know how he ended up after he refused to accept money for Lybian's oil.

    Actually, Polish intelligence read Enigma code for years, before giving the solution to France and Britain in early 1939 - three Polish mathematicians - Rejewski, Różycki and Zygalski cracked it in 1932 and even created the machine, called "bomb", that was able to crack the daily code. Afterwards. it was easy for British to read the code during the war and work on it further.

    Since 8-bit bytes have 256 values and we're working with 1024 values, we could take 5 bytes from a file at a time and divide the bits into 4 groups of 10. That'll give us 4 10-bit numbers which we can put through the algorithm. Once the 10-bit numbers have been encrypted, we split the bits back into 5 groups of 8 and then store the bytes in a new file.

    I learned so much from this video. There was a version of the Enigma used for the German Navy that had 8 total rotors (select 3), a fourth rotor, a settable reflector, and the rings on the rotors could be rotated to change the wiring for each letter. Additionally, the rotors could be placed in any order. How do these details change the total number of configurations? Great video I learned a bunch! Thank you!

  • @ralphedelbach

    Based on what I read, the fourth rotor was to the left of the other three and did not move automatically as the message was encrypted or decrypted on different machines. It could however be manual rotated/set into different positions but naturally had to be identical on each machine. Its design was also different that the other three and could not be interchanged with them.

Also "The Imitation Game" movie has a pretty decent portrayal of what happened.
