Re: My work

I’m glad to share possibly the first automatic decipherment of the second W.B.Tyler cipher. 😀 Nice! Did you have to change anything in your solver,…

Re: Z340 hypothesis: 2 letters per symbol

It can’t be solved with any of the current auto-solvers as far as I can tell. Edit your statement please. 😉 That’s not really a solution though. T…
