I have been using ROT13, but I’ve been looking for a post-quantum replacement so definitely I’m going to convert to SCREAM. It’s generally understood that qubits are unable to represent or even discern the little squiggly bits above normal Latin letters. Thank you for this important contribution to cryptography!

I wonder if Chatgpt can decrypt all of them just by analyzing vowel frequency, and then trying to find the algo on the internet.

  In my tests, ChatGPT 5 Thinking can handle a monoalphabetic substitution cipher if you prompt it a couple times to keep going.

  Not perfectly. I grabbed a random encoded line from these comments, and asked ChatGPT to decode it[1]. It determined the plaintext was: > Immediately thought of Moby, infact a quick search for this title... coincidental, but I would mention it in the page if I were you. and noted that it had "preserved punctuation and capitalization from the ciphertext". The actual plaintext should be: > Immediately thought of XKCD, infact a quick search for this title gives me XKCD, it could be coincidental, but I would mention it in the page if I were you. I've hit my free usage limit so can't currently prompt it further about its mistake.

    I pushed it a bit and it didn’t do so hot. https://chatgpt.com/share/68cf3b9f-decc-8007-8a5d-cc7b583d0e11 https://chatgpt.com/share/68cf3b9f-decc-8007-8a5d-cc7b583d0e...

The important part about applying ROT13 is the number of iterative applications. The security of even-numbered applications is undeniable. Odd-numbered is even better than that. I’m currently building an implementation with fractional rotation. Of course I will post a Show HN when it’s ready.

  oh so that's where æ comes from!

  Looking forward to seeing that, sounds fun and interesting!
