Universal Module for Hash Function in JavaScript

WARNING: At this time this solution should be considered suitable for research and experimentation, further code and security review is needed before utilization in a production application.

Introduction and Overview

This library is designed to 'universally' provide hash functions, i.e., it works both on most modern browsers and on Node.js just by importing from NPM/source code. Note that in the design principle, the library fully utilizes native APIs like WebCrypto API to accelerate its operation if available.

Installation

At your project directory, do either one of the following.

• From npm/yarn:

  $ npm install --save js-crypto-hash // npm
  $ yarn add js-crypto-hash // yarn

• From GitHub:

  $ git clone https://github.com/junkurihara/jscu.git
  $ cd js-crypto-utils/packages/js-crypto-hash
  & yarn build

Then you should import the package as follows.

import hash from 'js-crypto-hash'; // for npm
import hash from 'path/to/js-crypto-hash/dist/index.js'; // for github

The bundled file is also given as js-crypto-hash/dist/jschash.bundle.js for a use case where the module is imported as a window.jschash object via script tags.

Usage

Compute hash value

const msg = ...; // Uint8Array of arbitrary length
const algo = 'SHA-256';
hash.compute(msg, algo).then( (digest) => {
  // now you get a hash of msg in Uint8Array
});
