Hi, as many of you know, i've been a firm believer that d'Agapeyeff cipher is a product cipher (substituition + transposition). The difficulty in solving...
Tiago - Great to see you are still "hacking together some code". Kudos! If I may make a suggestion, it may be worth your time to cobble together a list of...
Tiago - If you are interested in my suggestion, I have provided a list of all UK cities, towns, and counties within a file in my personal directory. UK...
Hi, i haven't had a chance to post earlier, but I'd like to let you know the cipher still stands. Using UK city names for the polybius configuration didn't...
Hi Tiago - Glad to hear you report back. Sorry there was no joy on the other end. I agree with you that the statistics of the "letters" in the current setup...
As an aside, if anyone would like to turn my experiment into a poor man's distributed computing problem I'd be happy to share the program I'm using to test,...
Tiago - I forgot to mention that I did do some very rough analysis around the first digits in the pair and the second digits in the pair. My results were in no...
Dear Dagapeyeff_Cipher group members, as some of you might know, for the past 2 years I've been maintaning the dagapeyeff.com domain with some information from...
In the working through the 1939 Edition book by Alexander, I came across a test cipher on p. 104. Alexander writes, " I will leave the interested reader to...
Hi Thomas, I'm at work right now so I can't check my own copy of the 1939 edition right now, but I think you're confusing the key with the ciphertext here. The...

First of all, allow me to welcome Thomas to the Group. After some time away from this cipher, I've been doing some background thinking on possible new avenues...
Hello John ! Thank-you for your reply, John ! Once you see the book, it will become clear. Alexander presented the German Army example which is located...
Thank-you, Tiago. Will address your post after I get back from an appointment. Something I realized that might shed some light onto this, is that Alexander...
Hi again Thomas! I'm at home now, book in hand ;) I was right about the key: The numbers are mapped in that order to the regular alphabet. The ciphertext can...
I want to add to my last post about d'Agapeyeff claiming that "...it was quite easy to find the key and it is as follows:..." I fail to see how obvious and...
Yes, based on your work and explaination, was able to follow along with what you did. So...leaving out an "E"(35) in PASSD doesn't seem to that much of a...
Okay, I was a bit tired from work, that's why I didn't see HERE... But that also means that in such a short cipher already 3 Es were misplaced... And as you...
LOL...yeah, can understand that, John. Working all the examples in the book has been a challenge in and all by itself, with me as my own worst enemy. Have had...
Regardless of the form of transposition you suppose D'Agapeyeff used, I feel it's doubtful that his erasing steps would have caused him not to remember the...
Ok...to address your post, Tiago. On p. 146, Alexander explains how to decipher Vigenere Ciphers/Poly-Aplhabetic Systems. On p. 147, he writes: At first...
From what I understand, Alexander never said he forgot "what" he encrypted, only that he forgot "how" he did it. If he wrote down the message on a blackboard,...
Thomas, I'm not sure I'm following you on this one. If there were multiple alphabets at play on the unsolved cipher, you wouldn't have a steady Index of...
NFACT - It may be as you believe, the structure of the 158 Crypt gives us the key figures for the Vertical and Horizontal rows to compose our table. How I got...
To provide a foundation with the approach I'm taking with the 158 Cryptogram, is an attempt to understand Alexander D'Agapeyeff. It has to be seriously...
Alrighty, solved the Cryptogram. But...need some help finalizing the answer...kind of mind warped after working on this...a fresh mind would be helpful....
Unless I am completely missing something, you have just divided your initial letter set into four columns and - without logic - written the alphabet repeatedly...
Actually, the worksheet IS a logical sequence of the letters of the particular cipher to which it was applied. Every single one of the methods I employed are...
