Here’s a randomly generated cipher of unknown type. All of my ID tests put the correct type on top. Hill-climber solved it without a crib. I’ll include a short caesar-shift crib.

Here’s a randomly generated cipher of unknown type. I guessed the type without using any ID tests. I ran my hill-climber many times until I got a short phrase that made sense. It was straight-forward to fill in the rest of the words after that. I didn’t guess the complete key. I’ll put up a caesar-shifted crib.

Here’s a randomly generated period 7 CM bifid cipher. I originally tried it as unknown. One of my ID tests put CM bifid on top but I didn’t know the period. I tried various periods using converging key search and period 7 scored the highest but I didn’t include the correct range of routes to get the solution. I looked up the period and then was finally able to guess a correct range of possible routes so that converging key search got the solution. I’ll add a caesar-shifted crib.

Here is a Quag IV. I had great difficulty solving this, even after using the crib. I think I must have entered data wrong into my key search program, which failed to find the correct keys, resulting in a lot of wasted efforts.

Here’s a randomly generated cipher of unknown type. One of my ID tests put the correct type in fourth place, another put it in second place, and the third put it unanimously in first place. My hill-climber solved it without a crib but needed several runs.

Here’s a cipher of unknown type. My programs deduced the correct type and solved it without a crib, but I will provide a crib. The plaintext consists of two unrelated sentences chosen randomly from Gutenberg.org.

I’ve posted a zipped file with 10,000 syllabary and 10,000 numbered key ciphers at the links below.
Each line of the file is divided into 8 fields separated by commas. The fields are:
(1) The plaintext
(2) The key for the numbered key cipher
(3) The shift for the key
(4) Numbered key ciphertext
(5) Syllabary keysquare key
(6) Syllabary row key (10 digits)
(7) Syllabary column key (10 digits)
(8) Syllabary ciphertext.
There are a couple of restrictions: (A) Since the plaintext is the same for both cipher types, the plaintext contains no digits. (B) The numbered key keys are just random text passages.

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.
