Here’s a randomly generated cipher of unknown type. I had a hard time solving it. Within a certain range of periods all my ID tests got the correct type. But this period range was not correct for this cipher! With a different range none of my ID tests put the correct type on top. I tried a lot of different hill-climbing combinations and finally hit on the correct combination. With the correct combination of settings the hill-climber solved it without a crib. I’ll include a caesar-shifted crib.
