It would have been nice if the original post mentioned this.

The fact you're getting downvoted lays bare the bias of HN. Cryptographic proofs (math) clash against ideology, and ideology wins.

It's funny how the top comment in this thread is someone asking how leaking your public key would ever be useful. And a comment giving a very concrete example of how it's useful is at the bottom.

The repo was posted on HN and pretty much flagged immediately.

Oops, I meant to say "private key".

Maybe the average HN user would rather keep cryptography in the cryptography discussions and ideology in the ideology discussions. I don't necessarily agree with that, but it's not evidence of "bias".
