Crate ic_hash 

ic-hash — FIPS 180-4 and FIPS 202 hash functions

Pure-Rust, no_std, allocation-free implementations of the SHA-2 and SHA-3 families plus the SHAKE extendable-output functions.

use ic_hash::Sha256;
use ic_core::traits::Digest;

let d = Sha256::digest(b"abc");
assert_eq!(
    ic_core::codec::hex(d.as_ref()),
    "ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad"
);

Every type here implements ic_core::traits::Digest (or ic_core::traits::Xof) and ic_core::traits::SelfTest, so ic-fips can drive their known-answer tests generically.
