KMAC256 (cSHAKE256-based MAC) as defined in SP 800-185.

One-shot API

use crypto::sha3::Kmac256;

let key = b"super secret key 32 bytes!";
let mut tag = [0u8; 64];
Kmac256::mac(key, b"message", b"customization", &mut tag);

Incremental API

use crypto::sha3::Kmac256;

let key = b"super secret key 32 bytes!";
let mut kmac = Kmac256::new(key, b"customization");
kmac.update(b"hello ");
kmac.update(b"world");
let mut tag = [0u8; 64];
kmac.finalize_into(&mut tag);
