SHA224

A sha224 library

implements the SHA224 hash algorithms as defined in FIPS 180-4.

it's used to calculate account identifier from principal.

import SHA224 "mo:sha224/SHA224";
import Array "mo:base/Array";
import Nat8 "mo:base/Nat8";

let data = [097, 098] : [Nat8];
let expect = [
    219, 60, 218, 134, 212, 66, 154,
    29, 57, 193, 72, 152, 149, 102,
    179, 143, 123, 218, 1, 86, 41,
    107, 211, 100, 186, 47, 135, 139,
    ] : [Nat8];

assert(Array.equal(SHA224.sha224(data), expect, Nat8.equal));
