The one time I've tried doing this sort of "publish hash first, plaintext later" scheme, verification was hard because the hashing is vulnerable to whether or not the reader adds a newline after the text, a CR vs a CRLF, etc.

I think the best way is to post the command. So what I do is post

    printf "Hello World" | sha256sum

There is a /raw endpoint to make it easy. On a released pok you can do curl <pok-url>/raw | sha256sum
