This machine was able to use logic to decipher the encrypted messages produced by the Enigma. Looking for these patterns in the coded messages helped the team to calculate the daily settings on the Enigma machines.
The Enigma machine implemented a substitution cipher, which encrypts a message by substituting one character for another. Such ciphers go back at least as far as Julius Caesar, who used a simple substitution cipher to encrypt military orders.
A: Look at the four different Enigma code puzzles. What does change, what is different? I am blind. I do not see any difference!
A: The row number changes. Maybe you should try 8 as row number for the second row of the first puzzle. I still hang, can you show how to calculate any of the codes? A: See next section of this guide. All codes are solved there. In this last part I will talk about an insteresting mathematical property of the solution. This is not knowledge that you need to solve the puzzle and you may simply skip this.
But, if you read some of discussions about cracking the Wolfenstein Enigma Code you will see an emerging discussion. One side says you have to multiply, the other says you have to add repeatedly.
But who is right and who is wrong? Answer: The first is repeatedly adding, the second is multiplying. At the end both give the same result. As said in the previos section, the solution of the Enigma puzzle is: Row number times tumbler number, if the result is bigger then nine add the first digit with the second digit of the result.
If the result is still higher then 9 keep going with adding the digits and you will get a single digit number eventually. The part where we add the digits of the result until we get a single digit is known as the digital root [en. Let us denote the digital root as the function dr. This allows us to write the solution in mathematical form: dr Row Number x Tumbler number.
The digital root has a linear like properties. When we calculate the code segments from one tumbler to the next we can use this property to save us some multiplications. How, you may ask. For the first code segement we get the very simple solution R. In words: The code segment of the first tumbler is R. To caluculate the next code segment take the code segment for the previous tumbler, add R to it. If the result is larger than 9 add the first digit of the result to the second.
Conclussion: Which is the right and correct way to calculate the codes? But, the second way only works because the tumblers are numbered 1, 2, 3, 4 etc. At first it was hard to get what you were saying, reading it several times helped tho. MrRandomtastic 1 Dec, pm. I still have no idea what you are talking about but i tried. Huhn Geradesumme 16 Oct, am. Fizzing at the Bung 13 May, am. You realise in your explanation you are solving code 1 but your picture is of code 2 right?
I knew those equations meant something! Thank you! Excellent guide! LOL hey, gimme a break, I'm on vacation However, you posting the solution as a clever riddle that we need to unravel is the cherry on top.
