Trying to figure out which book Z might have been familiar with is probably a dead end after all. I was just thinking there could’ve been a popular fa…
I think if this cipher did not have the cycles in it, the solution would be out of reach (hopefully only temporarily). You should encode another one …
Maybe the repeats/patterns can be explained by the plaintext being very repetitive. The same thing repeating over and over again, or use of a very lim…
So, in this one, the + symbol must be either E, T, A, O, I, or N. It’s the last one, I didn’t want to make it too easy. 🙂 Just to add, this is hon…
I think you tried to induce high multiplicity by assigning some high counts to a few symbols and low counts to the bulk. That’s not quite it, but you…
OK, I cracked it (daikon, please confirm the solution I pm’d you), but it required many manual steps. Hint: Reduce the multiplicity before trying to …
So it seems I was able to stump all current auto-solvers after all? And only on the third try. I’m crackproof! 🙂 I’ll wait a couple of days before re…
Let me ask you, don’t the cycles prove that the message is left right top down? I think it is pretty certain at this point that Z340 should be read h…
This is the book with the Zodiac Alphabet that has a few similarities to the 408:
These are all great books, but the question is – which one would Zodiac be most likely familiar with? How would he get a hold of one? These days, it’ …
Ok, here’s my third, and hopefully last, attempt at unsolvable ciphers. Even though the previous cipher already doesn’t get solved by any of the curre…
I’m glad to be of some small help with my suggestions. 🙂 Using 6-grams should improve the solves even further, and 7-grams are not that impractical. …
If symbol 19, or the "+" symbol was the only polyalphabetic symbol, could this message be solved? I believe if you assign a new unique symb…
The more I think about the possibility of Z340 being in a different language, the less likely it seems. Let’s assume for a second that Zodiac was a sm…
