Unknown 10-2-19

Here’s a randomly generated cipher of unknown type. All of my ID tests put the correct type on top. A key search program got several possible keys. A hill-climber using the best scoring key got a fairly good partial solution. But to get the exact solution I had to use a Google search. I didn’t use a crib but I’ll include a caesar-shifted one.

  1. My Analyzer did not register the correct type as possible, but I recognized the type from the statistics. I’ll have to look into my tests to see where it went wrong. I did a key search and found the correct keys, but the oddball plaintext made the final solution difficult. Like BION I had most of the text right but looked up the quote online to be sure of the complete solution. It continues WIXLIV.

  2. Thats’ it!

    The plaintext is weird but that’s what you get sometimes when your computer selects a random text passage from a random document.

    1. I agree completely. Some of my postings have been like that, especially when it chooses two independent sentences. I found the error in my Analyzer program. I had the correct type among the types tested, but I had failed to give it a default value greater than zero! It always scored a zero and did not display.
