I recently got a pm asking for a hint. I will offer a few. There are no spaces. I have all of the words jammed together. I am afraid that I have made this too difficult. The code I have used works something like this
-- 1 2 3 4 5 6 7 8 9 .......
88 a b c d e f g h i .......
89 b c d e f g h i j.......
90 c d e f g h i j k.......
If for example the first letter of the sample were to be an "A" its number would be 88. If the second letter were to be a "D" its number would be 90. So the letter that the number represents changes at an even interval. I was just trying to have a little fun. If this proves too difficult, I will try to come up with another contest.
Correct me if I am wrong, but you made this impossible. If you were creating a code or cipher, for it to be of any use it would have to be decipherable by another user with a key. In your example, you are talking about a coordinate system that changes at an even interval. The problem is, your internals are changing, but the coordinate is incomplete. You supply the “y-axis” coordinate, but there is no “x-axis” coordinate. Granted, you are talking about the 1st and 2nd letters in the string, but even with the key, as a user, I won’t know what they are… (other than the fact that they change.) To make your example above correct, you would have to use 881=A, 902=D.
I believe your cipher similar to the internals of a tabula recta or Vigenère cipher, but you use dinome in the cipher when you should use a trinome.
Of course, if I am completely off base, I am an idiot and I apologize. :laugh:
