Very cool, all these brilliant minds together, could hold a "brains storm 'about the Z340 for a week, after you solved all together.
If I were there, i only understand that it was time for "coffee break" because i only "BREAK COFFE." :lol:
Now a coded praise for u Mr. Dave


Parabéns , que todos seu planos e desejos se realizem e que as melhores coisas sempre lhe aconteçam .Paz , saúde e sucesso.

I suppose we're writing the book here on the 340. Daikon's latest work on nomenclators is - to me - another big step in the right direction. More and more things are pointing towards transposition.

Hahaha, wimps. :) Figuring out the cipher's encryption method is like 90% of the battle. Well, for classical ciphers, modern ciphers are much more secure even if you know the encryption method.

That's interesting. I would've expected the opposite. There is a steady increase in the IQ of general population over the years (Flynn effect), so you'd think criminals are getting smarter too? Maybe they are using ready-made encryption tools, like PGP?

doranchak wrote:Dan also mentioned the 340 is still on the FBI's Top 10 unsolved codes list. I missed my chance to ask him what else was on that list - anyone know where to find it?


There are any number of "top 10 unsolved codes" lists, but I haven't seen the official FBI's one. Would be indeed very interesting to see it, but I suspect it's classified.

I totally get that feeling from time to time. We are not working on some cipher challenge created by someone in their spare time, or supposedly directions to some long forgotten and probably invented treasure. It's not from a book, or a movie, it was a *real* killer, who murdered real people with his own hands, and for no real reason other than "just for fun". And once deciphered it might be even creepier than Z408 and equally real...

Look forward to hearing updates about this and watching your video

Dan gave some brief responses to my questions:

(Regarding what techniques the FBI tried on the 340): "I have looked through the original exam files but have not actually made a list or inventory of their methods and tests. I can say they were quite thorough and very skilled, and made extensive use of the computer technology they had available in the 70s."

(Regarding the other entries on the FBI's top 10 unsolved codes list): "All of our top 10 unsolved codes are either active FBI investigations or cases not owned by the FBI so we don’t have dissemination authority."
