Cordova crypto file plugin

HTML source file is encrypted at build, and decrypted at run.
https://www.npmjs.com/package/cordova-plugin-crypto-file

Add Plugin

cordova plugin add cordova-plugin-crypto-file

Purpose

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

Important

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.

Steps:

  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

  1. 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));
    }
  1. Add this instead:
    @Override
    public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
      return super.shouldInterceptRequest(view, request);
    }

Then the plugin will work.

Configuration

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:

cryptoPort

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

Encrypt

cordova build [ios / android]

Decrypt

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

Encryption subjects.

Default

  • .html
  • .htm
  • .js
  • .css

Edit subjects

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.
