I still don’t think his solution is correct, but it was sort of interesting to watch him make his case.

Here is what happens when you put in Craig Bauer’s "Here it is…" substitution into doranchak’s webtoy.

It is far different from the solution he shows in his presentation:

Even when considered as a 7 row message there is nothing readable after the third line. Realize that at 7 rows the cipher has a multiplicity of nearly 0.5. And with the amount of cheats that he employs – heavy polyalphabetism, non-letters, spaces, convenient word misspells, 2 letters to 1 symbol substitutions – really any message can be fit into these 7 lines.

There is no doubt in my mind that the FBI would classify this as a non-solution if it would ever be submitted.

How to know that you haven’t solved the Zodiac-340 cipher: http://www.cse.unt.edu/~garlick/researc … ac-340.pdf

you can write pretty well anything in the first three lines and the last line remains pretty free as well.
