SHA-512 in rust-arkworks

[skaunov]

I noticed that both c are produced with SHA-256 in <./javascript>. Is it ok to that crate to do it with SHA-512?

Oh we are removing sha512 everywhere and only using sha256.

What would be corrected test vectors for

zk-nullifier-sig/rust-arkworks/src/tests.rs

Line 215 in e7490a8

pub fn test_against_zk_nullifier_sig_c_and_s() {

in that case?

Feel free to just calculate that for i.e. the test anvil sk/pk in the implementation and use that as a test; if the other implementations all give the same result, we can be pretty confident that its calculating correctly!
