Function hash_xof

pub fn hash_xof(
    t: MessageDigest,
    data: &[u8],
    buf: &mut [u8],
) -> Result<(), ErrorStack>

Computes the hash of the data with the XOF hasher t and stores it in buf.

Examples

use openssl::hash::{hash_xof, MessageDigest};

let data = b"\x41\x6c\x6c\x20\x79\x6f\x75\x72\x20\x62\x61\x73\x65\x20\x61\x72\x65\x20\x62\x65\x6c\x6f\x6e\x67\x20\x74\x6f\x20\x75\x73";
let spec = b"\x49\xd0\x69\x7f\xf5\x08\x11\x1d\x8b\x84\xf1\x5e\x46\xda\xf1\x35";
let mut buf = vec![0; 16];
hash_xof(MessageDigest::shake_128(), data, buf.as_mut_slice()).unwrap();
assert_eq!(buf, spec);
