Package Exports

isomorphic-webcrypto
isomorphic-webcrypto/index.js
isomorphic-webcrypto/index.mjs

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (isomorphic-webcrypto) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

isomorphic-webcrypto

isomorphic webcrypto library for IE11+ in 3kB

What?

There's a great Node polyfill for the Web Crypto API, but it's not isomorphic yet. This fills the gap until it is.

IE11 and versions of Safari < 11 use an older version of the spec, so the browser implementation includes a webcrypto-shim to iron out the differences. You'll still need to provide your own Promise polyfill.

Install

npm install isomorphic-webcrypto

Usage

There's a simple example below, but there are many more here.

const crypto = require('isomorphic-webcrypto')
// or
import crypto from 'isomorphic-webcrypto'

crypto.subtle.digest(
  { name: 'SHA-256' },
  new Uint8Array([1,2,3]).buffer
)
.then(hash => {
  // do something with the hash buffer
})

Compatibility

See webcrypto-shim's supported browsers

I just want to drop in a script tag

You should use the webcrypto-shim library directly:

<!-- Any Promise polyfill will do -->
<script src="https://unpkg.com/bluebird"></script>
<script src="https://unpkg.com/webcrypto-shim"></script>
