Here’s a randomly generated cipher of unknown type. One of my ID tests put the correct type in first place, one put it in second, and one put it in sixth. I chose the correct type on my first try. A hill-climber solved it using only the ciphertext.
When I was working on the 11-24-19 unknown I wrote a program to drag a crib “globally” over a ciphertext, testing all possibilities at once. I’ll include a caesar-shifted crib that could make use of a program like the one I wrote.
