Yes, "it" and "hzw" both have the same number of letters, which is
three. This is because in a simple substitution cipher, each letter in
the plain text is replaced with a different letter, so the length of
each sequence of letters remains the same in both the plain text and encrypted forms.

See if it can decrypt this then:

That is also a "substutition cipher" of sorts, just not necessarially
'well known'. Richard Heathfield of sci.crypt termed it SCOS for Sci
Crypt Open Secret. The 'key' to the above is "5 8".
It will be interesting if it can decrypt that one or not.
PS - I encrypted the paragraph of your post that I quoted above
(without quote prefixes) with scos to create the encrypted portion
above, so you will know if chatgpt manages to figure out the pattern.
It didn't even try, denying knowing anything about Sci Crypt Open
Secret, when prompted. It says it was trained on Usenet posts, but
denies knowledge of specific posts or posters.
I'm not surprised; it cannot even replicate the Lazy Dog success with a different character mapping.
