window.crypto for NativeScript via a WebView
npm i --save nativescript-webview-crypto


npm Dependency Status

This brings window.Crypto to your Native Script 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 cavaets.

If you are using Angular2 with Nativescript, you should use nativescript-angular-webview-crypto.

This requires being setup properly with NativeScript first. Then install this as a plugin:

tns plugin add nativescript-webview-crypto


Rendering the PolyfillCrypto components will start up a WebView to transparently proxy all the crypto calls to. It will also set the crypto global variable.

<Page xmlns="" xmlns:WebViewCrypto="nativescript-webview-crypto">
<WebViewCrypto:WebViewCrypto />

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

You can look at an example repo running this example for symmetric encryption in NativeScript.
