cordova plugin add cordova-plugin-crypto-file

This plugin was created to solve the issue of using cordova-plugin-ionic-webview with cordova-crypt-file, refer to #75

The file IonicWebViewEngine.java (that is inside the ionic webview plugin) needs to be modified for this plugin to work and for the source code to be encrypted.

1. After adding the cordova-plugin-ionic-webview, navigate to the following location:

For cordova-android@6 :

platforms/android/src/com/ionicframework/cordova/webview/IonicWebViewEngine.java

For cordova-android@7 :

platforms/android/app/src/main/java/com/ionicframework/cordova/webview/IonicWebViewEngine.java

2. Remove the following code:

    @RequiresApi(Build.VERSION_CODES.LOLLIPOP)
    @Override
    public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
      super.shouldInterceptRequest(view,request);
      return localServer.shouldInterceptRequest(request.getUrl());
    }

    @TargetApi(Build.VERSION_CODES.KITKAT)
    @Override
    public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
      return localServer.shouldInterceptRequest(Uri.parse(url));
    }

3. Add this instead:

    @Override
    public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
      return super.shouldInterceptRequest(view, request);
    }

Then the plugin will work.

You can also change the port in the config.xml, but it needs to be the same port as the one used in the "cordova-plugin-ionic-webview".

To change the port, do the following:

<preference name="cryptoPort" value="8080" />

cordova build [ios / android]

cordova emulate [ios / android]
or
cordova run [ios / android]

• .html
• .htm
• .js
• .css

You can specify the encryption subjects by editing plugin.xml.

plugins/cordova-plugin-crypt-file/plugin.xml

<cryptfiles>
    <include>
        <file regex="\.(htm|html|js|css)$" />
    </include>
    <exclude>
        <file regex="exclude_file\.js$" />
    </exclude>
</cryptfiles>

Specify the target file as a regular expression.
