Sigaba challenges published on MysteryTwisterC3

Several cryptanalysts (M. Stamp, N. Kopal and G. Lasry) have published several challenges on the Web site MysteryTwisterC3, a site dedicated to Cryptographic challenges.

Sigaba challenges published on my Web site

After having a good understanding of how the Sigaba machine and its procedures worked, I wrote a program that simulates its operation. I then published a web page on the evolution of progress regarding its cryptographic analysis. In my Challenge page (link), I wanted to give readers different problems that illustrate the methods exposed in the Cryptanalysis page.

My problems (almost all) are dated and use the procedures in force at their time. I tried to make them realistic.
