Readme
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
npm install --save react-native-webview react-native-webview-crypto
react-native link
Android
create a file called blank.html in android/app/src/main/assets
<html/>
known issues
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'
getRandomValues
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.
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 (
<View>
<PolyfillCrypto />
<App />
</View>
);
}
}
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.
