Re: My work

Wow, that’s impressive! I’m definitely downloading. I think I’ve came across this corpus, but thought it would be too large to process. The corpus I’m…

Re: Glen Claston’s 340 observation

I think he measured the distances between recurring bigrams, and then looked for factors in those distances that occur more often than expected. It’s…

Re: Glen Claston’s 340 observation

"IofC" is easy, it’s Index of Coincidence (IC or IoC). But I can’t quite understand the rest. Especially the part about "numbers" …

Re: Cipher challenge

It’s an interesting idea, but what exactly does using 4/5/6-grams in parallel accomplish? I must’ve missed an important key point in the discussion. :…

Re: Cipher challenge

I’m getting a stable solve for both ciphers as well using my own solver, but with a pretty low overall score, which means the recovered plaintext isn’…

Re: 408, the last 18- all roads lead to E, or maybe RS?

Thanks for running the experiment! Seems to suggest it was done on purpose, considering only 1 in 35 chance of it happening, well, by chance. 🙂 Altho…

Re: 408, the last 18- all roads lead to E, or maybe RS?

Hmm, yes, perhaps there is a standard way of building the key for a homophonic substitution cipher described in one of the books, that has this proper…

Re: 408, the last 18- all roads lead to E, or maybe RS?

It’s a curious find indeed! It makes sense that all of the letters end in E because E maps to itself. So it in a sense short-circuits any further link…

Re: z340 z32 morse theory

Right off the bat, you have a "C" that translates to dash and then to a dot elsewhere. Similarly stands for a dot at the start of the ciphe…

Re: My work

Hows your solver coming along? Any plans for a release or working on a GPU version? So, I’ve finally implemented an OpenCL version of my solver runn…

Re: "Beale Cipher Three" test cipher

I might have to officially give up. Know when to hold ’em, know when to fold ’em, as they say. 🙂 I don’t think I’ll be able to solve it without hints…

Re: Homophonic substitution

Not wrapping around the cipher it might be as rare as 1 in a million (versus 340 randomized) and we didn’t have to search through millions of variatio…

Re: Homophonic substitution

Simple Proposed Cipher: 1. Zodiac drafted the plaintext horizontally and there were slightly more than 323 symbols. The resulting number of rows is 1…

Re: Homophonic substitution

Daikon what is your thought on the bigram peak a period 19 or 15 mirrored? Not wrapping around the cipher it might be as rare as 1 in a million (versu…
