Challenge "Enigma Messages with Repeated Letters — Part 1"  

  By: admin on Sept. 26, 2013, 3:05 p.m.

In this part of this series of Enigma challenges, a plaintext message consisting of one letter which is repeated several times has been encrypted by the Enigma I. What is the letter we are looking for?

I solved this challenge (and the letter I submitted was correct) but I was not able to determine the precise setting of the enigma. I only found the letter that gave me the longest ciphertext which was same as part of ciphertext in the challenge.

So either I have made a mistake or this challenge has no solution.
It is likely that my algorithm could have some minute error and that is why this happened.
I would like if somebody, who has already solved this challenge and thinks that she/he has the correct setting, could send me the precise settings of enigma in PM to me. Thanks!

Finally I found the error in my algorithm. There were some problems with stepping of two rotors.
Thanks to those who replied me.

Hi, I'm looking for George Lasry. I am hoping to ask him about another cipher that is not on MTC3. Is he around?
