This is a simple example to run openpgpjs using react-native-webview.
This is a full react-native project. You can simply clone and run on simulator or real devices.
Here we use react-native-webview to open a simple html which we load openpgpjs library by adding <script/> like this:
<html>
<body>
<script src="https://unpkg.com/[email protected]/dist/openpgp.min.js"></script>
<div>hello word</div>
</body>
</html>
Then, we can inject some js code to run openpgp by calling the method injectJavaScript().
Example javaScript code to use openpgp:
const jscode = `(async () => {
const message = await openpgp.createMessage({
binary: new Uint8Array([0x01, 0x01, 0x01]),
});
const encrypted = await openpgp.encrypt({
message, // input as Message object
passwords: ["secret stuff"], // multiple passwords possible
format: "binary", // don't ASCII armor (for Uint8Array output)
});
console.log(encrypted); // Uint8Array
};
true;`;
Finally, inject this code by:
webViewRef.current.injectJavaScript(jscode);
That's it!
