Here’s a randomly generated cipher of unknown type.
The random forest ID test put the correct type in eighth place. The Bion’s Gadgets neural net test didn’t mention the correct type. My experimental neural net ID test put the correct type in first place and no other types were listed, so I tried its type first and solved it. A hill-climber got a practical solution without a crib. A key-search program also got the solution without a crib. I’ll include a caesar-shifted crib.

My Analyzer didn’t rank the correct type as possible, but I eventually tried it and my hillclimber solved it.

A new member (Gerard) has just posted a comment on a post from months ago where it will not be seen requesting assistance in solving the cipher below. I’m reposting the text here and will send him a link to this page. If anyone solves it or has suggestions, please post them in the comments here.

Could you help me solve this?

Here’s a randomly generated cipher of unknown type. Two of my ID tests put the correct type in second place, but the third ID test didn’t mention the correct type. A more specific test put the correct type on top. Two of my solvers got it without a crib, but the third solver needed the crib.

Here’s a randomly generated cipher of unknown type. It took me a long time to convince myself I had the correct type even though it was in second place in all my ID tests. It also took a long time to solve it without a crib. I ran my hill-climber many times until it suddenly got a good partial solution that I was able to finish off. I’ll include a caesar-shifted crib.

This 2-sentence ciphertext was generated by my random con generator. The text is from gutenberg.org. My program diagnosed it as fractionated Morse and my hill-climber solved it in 1.57 seconds. I’m not going to provide a crib since I think it’s not necessary

Two ciphers today!

Here’s a randomnly generated Gromark cipher. As usual none of my ID tests put Gromark on top. My PH hill-climber solved it without the primer and without a crib. I’ll add primer and crib in caesar-shifted form.

This con is a randomly selected sentence from the Internet. My Analyzer placed the correct cipher type in 17th place! My hill-climber solved it without a crib, but I am including a Caesar-shifted crib: HUKOVWL. Correction: The first sentence was too short, so my program selected the beginning of another sentence to lengthen it. The second sentence is truncated in the middle of a word.
