Re: ORDER OF CODE BLOCKS

Another possible reason that cycles are broken in the 3rd part is that he got tired after doing the first 2 parts and took a break before doing the 3r…

Re: ORDER OF CODE BLOCKS

I was thinking about how did Hardens figure out the correct order of the code blocks too. Considering, that what they claimed helped them crack it, wa…

Re: Solving the 405

And that’s how I think it will eventually unravel.. Yeah, no, sorry, at this point it is quite clear that Z did something else when encoding Z340 be…

Re: Solving the 405

I think I just got lucky. After I locked "ILIKE" in the beginning, I did a bunch of restarts and at one point I saw "ILIKEITWITHICECREA…

Re: Solving the 405

Sorry to be late to the party. I thought I’ll give it a try. High multiplicity is indeed a huge stumbling block, but I was able to use your hint (star…

Re: FBI analysis (by Dan Olson) of Z340 might be wrong

ABCBCBC. BC repeats 2 times and CB repeats 1 time for a total of 3 bigrams for this string. I see! It is similar to bigram index of coincidence then…

For columnar transposition, which are basicly the permutations of 17 columns/elements, there are number of different combinations. And the solution i…

Re: FBI analysis (by Dan Olson) of Z340 might be wrong

That’s what I said in my last post at: viewtopic.php?f=81&t=267&start=140 Yeah, I didn’t get your question at the time. Now I understand it p…

Re: FBI analysis (by Dan Olson) of Z340 might be wrong

I think that the problem here is that there are a nearly infinite number of these transpositions. It would take a little while to try them all. Over…

Re: FBI analysis (by Dan Olson) of Z340 might be wrong

After some more experiments with constructing ciphers similar to Z340, I’ve realized that there is one more common assumption that can be thrown out o…

Re: Not all homophonic substitutions can be auto-solved

With IoC 0.075 a reasonable automatic solve came through Hmm, interesting. It didn’t occur to me to adjust IoC for automatic solves. I couldn’t eve…

Re: Popular cryptography books in the ’60s?

I find it interesting in relation to the Harden’s and also because of a reference from Wikipedia about a special case of rail fence (Zigzag cipher): …

Re: Not all homophonic substitutions can be auto-solved

As I’ve said before I believe the limited vocabulary artificially raise the multiplicity. So it’s a multiplicity problem more than anything else. Y…

Re: Not all homophonic substitutions can be auto-solved

I’ve got this now, I guess I was close earlier after seemingly finding EIGHT, HUNDRED, FIFTY, etc… I should have stuck with it. So, how did you s…

Re: Not all homophonic substitutions can be auto-solved

EDIT: I actually think I have it exact now. I’ve sent you a PM. You do have it *exact* to the letter. Wow! I had to abbreviate degrees/minutes/seco…
