Re: Why line 11 of 340 is important

I’ve always thought the last line seemed to suggest "Signed" from the middle zodiac symbol backwards to the left, and then "Zodiac&quot…

Re: This man thinks the 340 is a fake cipher

Transposition of the plaintext would make the cipher look fake in such a test. Agreed. Do you think it is also plausible to simply hand tweak a ci…

Re: This man thinks the 340 is a fake cipher

Period 2 bigrams are also missing. A 340 character 408 has 38 period 2 bigrams, though these are less likely to occur. Period 2 bigrams are 2 position…

Re: Strongest known algorithm for Z408

What I like about the pareto optimality approach is that it helps get around the problem of knowing how important the tradeoffs are between different …

Re: Strongest known algorithm for Z408

I did not see any source code for AZdecrypt, nor an algorithm description. Here is a basic run down. Load some 5-gram letter log frequencies into a …

Re: Strongest known algorithm for Z408

Jarlve, do you know why simulated annealing works better with smaller changes? I also noticed that trying to do too much at each step seems to lead t…
