Hi Largo look forward to collaborating with you on this. A lot of people think that there is something odd with the huge amount of "+" sig…
They are great visualization but i find the 408 experiment very interesting. Thanks for sharing.
By "rail size", do you mean the number of rows in a rail fence cipher like this one? I would say that this is a 25 x 3 railfence cipher beca…
For the 340, I found all period x bigram repeats where x is a divisor of the position spacing of the repeat. Here is the table. On the left is the per…
Hi Largo, Welcome. look forward to hearing more about your cipher developments Regards Bart
Hi Guys, Just want to consolidate some of my ideas/assumptions and theories or at least kick them around so as to try and focus and take stock of what…
At period 39, do you also find ngrams that are spaced apart by multiples of 13? So strange, all these multiples of 13. And the "my name is"…
Last night i ran through the Railfence cipher 2 to 100 and used Akdecrypt test the output All scored around 19k to 20k with no solution. I currently …
Here is the 340, rotated 90 degrees to the right, and drafted into a 17 x 20 grid: 4 11 19 3 11 34 6 40 16 38 55 17 21 22 5 46 42 20 18 1 37 51 19 36…
I figure we have taken it this far, so we might as well explore a few different directions. The message may not read from left to right, top to botto…
Hi Smokie. Sorry I missed this message. I will try and answer and work through as soon as possible Regards Bart I checked a block of messages from:
Peak sigma is 9.0 at width 7. I’m very pleased with how clearly the key length shows up in the shuffle-based normalization of columnar IoC. Seems li…
Here you go hopefully it is still relevant. Thanks. I ran the shuffle-based columnar IoC normalization on it and it did a pretty good job of identif…
I don’t know if coincidence counting detected a Vigenere step in the 340 cipher, but it may have detected some other cipher step that we don’t know ab…
Can you post the Vigenere cipher you used for you columnar IoC test? I want to run it through my process that compares it with shuffles, to see how t…
