react-native-webview-crypto


Working version based on /saulshanabrook/react-native-webview-crypto and PR https://github.com/saulshanabrook/react-native-webview-crypto/pull/9

This brings window.crypto.subtle to your React Native application. It does this by communicating with a hidden WebView, which performs the actual computation.

Refer to the webview-crypto repo for most of the code and some caveats.

Installation

``sh
npm install --save react-native-webview react-native-webview-crypto
react-native link
`

$3

create a file called blank.html in android/app/src/main/assets

`

`

$3

if you use react-native-crypto and get warnings about cyclic require make sure to import it before the bridge

`
import 'react-native-crypto'
import WebviewCrypto from 'react-native-webview-crypto'
`

$3

for complete compatability with webcrypto (window.crypto.getRandomValues) you can install react-native-crytpo or react-native-get-random-values

Usage

Rendering the PolyfillCrypto will start up a WebView to transparently proxy all the crypto calls to.

`javascript
import React, { Component } from "react";
import { View } from "react-native";

import App from "./app";

import PolyfillCrypto from "react-native-webview-crypto";

class TopLevelComponent extends Component {
render() {
return (




);
}
}

AppRegistry.registerComponent("WhateverName", () => TopLevelComponent);
`

Now, in any of your code, you can access window.crypto.subtle`, just like you would in a browser.

There is also an example repo which runs some example crypto using this library.
