npm install react-native-webview-crypto
Working version based on /saulshanabrook/react-native-webview-crypto and PR https://github.com/webview-crypto/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.
``sh`
npm install --save react-native-webview react-native-webview-crypto
react-native link
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'
for complete compatability with webcrypto (window.crypto.getRandomValues) you can install react-native-crytpo or react-native-get-random-values
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.
Example repo
There is also an example repo which runs some example crypto using this library.
