My Facebook group has a significant list of resources for learning cryptanalysis and cryptography. Regards Bart
Thanks for posting David.
Hi Jarlve, Thanks for the link. I am not familiar with this material so i will have a read. I am trying to get my head around your other posts as well…
Hi David. Not really but checker boards have a broad interpretation and there are many that could be classed as sush. The work i was looking at was un…
I have been experimenting lately with checker board cipher where for ease of explanation a x y grid gives a plain text symbol whos location is defined…
I post this here for completeness. I recently came across some loose observations that vaguely implied a right to left, top down writing of the plaint…
Thanks for posting those resources – they are very useful. AMSCO cipher looks interesting especially with regard to odd phobia. I only have done a sm…
In extension to the cipher library from bion that David posted (looks like you had a great trip BTW) here is a list and statistical metrics for most A…
I have a new shuffle spreadsheet, where I can select or exclude any of the positions for regional shuffle tests. Looks like you are doing some awesom…
Hi. Need help with the basics. Not sure how and what cipher programs to use to run a pattern. The pattern should be ran left to right, up and down and…
I am working on the grille cipher I have thought about the grille also but i can’t think of a proper way to implement it. I am glad you are take it o…
I know there is a half baked thread on morse code (each to their own) on here but has anyone done a proper frantionaled morse research on z340? I am c…
BartW I have never been able to emulate the same results from a scytale crypto tool as I have from manually constructing and deconstructing back to a …
The cipher order syctake/HSC wouldnt have much effect except reordering the HSC cycle symbols. The scytale should be able to be modeled by the period/…
I think you are correct in that Z generated the key code before encoding the cipher. it is interesting that the key space for Z340 63 (9×7) and Z408 5…
