This is a list of types of ciphers that are encrypted with their own ciphers. If a given cipher requires a key, then the cipher is the key as well. Also these are all actual ciphers, not methods to crack them like "frequency analysis". It will require some brute-force, but they are all classically well-known ciphers and I believe most will be easy and some even trivial. This is posed as a challenge who can get them all first and also a good resource for newcomers wanting to learn some basic ciphers commonly used. Good luck!

  • $\begingroup$ (Also, I've downvoted because this seems to be low-effort. As you said, pretty much all of these are trivial, and this puzzle could easily be made by scanning through Rumkin or dcode.fr's lists and encrypting all of them. I would highly recommend not using solely ciphers if you want to make a high-quality puzzle - or not using ciphers at all, even.) $\endgroup$

    $\begingroup$ For what it's worth, here's another puzzle that uses the same premise, but is more elaborate (and definitely was more challenging). $\endgroup$
