Here’s a randomly generated cipher of unknown type. All my ID tests put the correct type on top. A hill-climber solved it quickly.

Here’s a randomly generated cipher of unknown type. All my ID tests put the correct type on top. A PH hill-climber solved it but had to use the crib. I also solved it by key search without a crib, but that was after I had already solved it with the hill-climber. key search took a long, long time. The hill-climber was much faster.

caesar-shifted crib: JBBMJWJYMJDBJWJLT

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.

This one was a tough one to diagnose the type even though the correct type ranked fairly high in my analyzer. I needed the crib to solve it. It fit in multiple places.

Here’s a randomly generated cipher of unknown type. One ID test put the correct type in second place, one put it in third place, and one didn’t mention it. Looking at the ciphertext I guessed the type correctly and my hill-climber solved it without a crib. I doubt if it needs a crib.

Here’s a randomly generated cipher of unknown type. All my ID tests put correct type on top. I needed the crib to solve it. Both hill-climber and key search got practical solutions. Finished off a few letters by hand.

Caesar-shifted crib: WYJWUFXYYJSYWFNS

My Analyzer placed the correct type in 10th place. I had to peek at the type. Then my hillclimber didn’t solve it, so I had to place the crib. I finally solved it by key search.

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.
