Although Polish mathematicians had worked out how to read Enigma messages and had shared this information with the British, the Germans increased its security at the outbreak of war by changing the cipher system daily. I don’t really understand what some mean by the original size message , i should only write the 50 first chars ? The reverse process is called decryption. An Enigma machine allows for billions and billions of ways to encode a message, making it incredibly difficult for other nations to crack German codes during the war — for a time the code seemed unbreakable. Enigma Part 1: German Enigma’s encryption and its major weaknesses | #13. The Enigma machine is a piece of spook hardware invented by a German and used by Britain's codebreakers as a way of deciphering German signals traffic during World War Two. The Enigma cipher was a field cipher used by theGermans during World War II. Enigma gave the Nazis and Axis powers a material advantage over the Allies until it was subdued by counter-encryption activities. To be simple for the encoding with the word "ABCD" : Step 1: apply CAESAR with the incrementing number (let’s say 4 here), Step 2 : translate trough first rotor (let’s say "BDFHJLCPRTXVZNYEIWGAKMUSQO" here), Step 3 : translate trough second rotor (let’s say "AJDKSIRUXBLHWTMCQGZNPYFVOE" here), Step 4 : translate trough third rotor (let’s say "EKMFLGDQVZNTOWYHXUSPAIBRCJ" here), So after those 4 steps "ABCD" is encrypted to "KFDI", Step 1 : translate from third rotor (let’s say "EKMFLGDQVZNTOWYHXUSPAIBRCJ" here), Step 2 : translate from second rotor (let’s say "AJDKSIRUXBLHWTMCQGZNPYFVOE" here), Step 3 : translate from first rotor (let’s say "BDFHJLCPRTXVZNYEIWGAKMUSQO" here), Step 4: undo CAESAR with the incrementing number (let’s say 4 here), So after those 4 steps "KFDI" is decrypted to "ABCD". A series of hints and finally fu I am developing a java simulation of one of the encryption machines used in World War II by the Nazi military--The Enigma.
