Sha3 JavaScript Webassembly

A simple sha3 in Webassembly for better performance.

The source code is in rust which is compiled with wasm-pack

benchmark

the benchmark was done with Bechmark.js on Firefox.

The comparison was made with the lib js-sha3

function	sha3-js-wasm	js-sha3
sha224	266,328 ops/sec	87,343 ops/sec
sha256	278,208 ops/sec	77,950 ops/sec
sha384	272,943 ops/sec	62,983 ops/sec
sha512	239,967 ops/sec	46,295 ops/sec
keccak224	241,113 ops/sec	54,068 ops/sec
keccak256	268,955 ops/sec	38,450 ops/sec
keccak384	260,621 ops/sec	32,019 ops/sec
keccak512	221,526 ops/sec	30,533 ops/sec

Installation

with npm :

npm install sha3-js-wasm

or then with yarn :

yarn install sha3-js-wasm

Usage

import * as wasm from "sha3-js-wasm";

wasm.sha224('hello world')
wasm.sha256('hello world')
wasm.sha384('hello world')
wasm.sha512('hello world')
wasm.keccak224('hello world')
wasm.keccak256('hello world')
wasm.keccak384('hello world')
wasm.keccak512('hello world')

Todo

• unit tests
• the shake method
