I have added some new features in the last days. However, I don’t want to release today, because the version is not stable enough yet. However, I’m p…
Thank you Quicktrader for the detailed description of the key frequencies! I will take a closer look at this, it looks really interesting. Well, bes…

The problem is that we cannot even say that the cycles are interrupted though that is one possibility. We need to formulate some hypotheses for the 34…
With sequential homophonic substitution ciphers, even when they are "perfectly cyclic", they are not perfect as in your first text and all s…
