Snefru

Extends:

src/hasher/hasher32be.js~Hasher32be → Snefru

Calculates Snefru v2.0 (2 rounds 128, 4 rounds 256), Snefru v2.5 (8 rounds) hash

Example:

Calculates Snefru128/8 hash from string "message" - ES6 style

import Snefru from "crypto-api/src/hasher/snefru";
import {toHex} from "crypto-api/src/encoder/hex";

let hasher = new Snefru();
hasher.update('message');
console.log(toHex(hasher.finalize()));

Calculates Snefru128/8 hash from UTF string "message" - ES6 style

import Snefru from "crypto-api/src/hasher/snefru";
import {toHex} from "crypto-api/src/encoder/hex";
import {fromUtf} from "crypto-api/src/encoder/utf";

let hasher = new Snefru();
hasher.update(fromUtf('message'));
console.log(toHex(hasher.finalize()));

Calculates Snefru128/8 hash from string "message" - ES5 style
