UNKNOWN 11-16-19

Here is a randomly generated cipher of unknown type. My work on this one turned into a comedy of errors. I eliminated several types, including the correct one, by pasting the wrong ciphertext into some of my conversion programs. Then I decided it was a type that probably needed a crib, so I pasted the Caesar-shifted plaintext into a minimum crib program and started it running. After 15 minutes the program hadn’t come up with a crib. This was too long so I guessed there was a bug in my program. I searched through the source code but couldn’t find anything wrong. About this time I noticed I had used the wrong ciphertext in some of my programs. Putting in the correct ciphertext led to the correct ciphertype. But it still took me about half an hour to solve the con. I didn’t need a crib. But I’ll add a Caesar-shifted crib.

  1. That’s a funny story, BION. I’ve had the same sort of thing happen to me.

    It continues HAZZNKSUYZ. My Analyzer ranked the correct type as #3, but I tried it second. My autosolver for this type produced a partial solution almost instantly. The solution was only 90% right, but the entire sentence could be read and hand corrected without needing the crib or the original source.
