Many thanks go out to the Poles for breaking the Enigma ciphers.

actually, no letter encrypted on an ENIGMA would ever encrypt as itself. That was one weakness of the machine. But what really bought the code down was the overuse of stock phrases such as "Hiel Hitler". If one phrase is common to every message, it stick out like a sore thumb to a cryptoanalyst. The Allies' efforts could have been very easily thwarted by re-encrypting the coded message using a different starting setting, which would have allowed some letters to be shown as themselves.

You have to admit...the Germans were so bloody clever for the time it's scary! Without them Russia or the States wouldn't have got into space race. And Hitler was way ahead of everyone with the Atomic Bomb! Lets just thank our lucky stars he didn't get to perfect it!

I heard a lot of that machine and finally I can see one "alive". :) Thank you for the video!

Polscy kryptolodzy: Marian Rejewski, Jerzy Różycki i Henryk Zegalski ukończyli wydział matematyki Uniwersytetu w Poznaniu. W 1932, pracując w Biurze Szyfrów Sztabu Głównego Wojska Polskiego, udało im się złamać kody szyfru niemieckiej Enigmy, najdoskonalszej wówczas maszyny szyfrującej i tym samym pomogli zmienić losy II wojny światowej umożliwiając wywiadowi brytyjskiemu rozszyfrowywanie przechwytywanych niemieckich rozkazów

Polish kryptolodzy: Marian Rejewski, Jerzy Różycki and Henryk Zegalski finished in Poznan the department of mathematics of University. In 1932, the most working in Office of Codes of Staff Main Polish Army it pretended them to break the codes of code of German Enigma, perfect wówczas the coding machine and they helped to alter fates II world war making possible with the same the British interview the decoding of intercepted German orders

from what I read it was a very complex machine, had the operators been more careful and changed the settings each day we might never had broke the code.

but I also read that we captured one and so take it apart and that helped break the code.

Fatal flaw of Enigma: the letters on the reels were in alphabetical order, making it easier to decode.

It was there, on July 26, 1939, with World War II looming only five weeks off, that the Cipher Bureau's chiefs, Lt. Col. Gwido Langer and Major Maksymilian Ciężki, the three civilian mathematician-cryptologists, and Col. Stefan Mayer (Polish General Staff intelligence chief), on General Staff instructions, revealed Poland's Enigma-decryption achievements to intelligence representatives of France and British cryptologists
