securing assets (images, sound files)

Hello to the community! I’m new here so please bear with me. :slight_smile:

I’ve read a lot about securing assets for Cocos2d-x and, for images at least, TexturePacker seems to be the common answer for many developers. I’m still at a loss when it comes to sound files, though.

I have two questions:

  1. Are there other alternatives to packing resources (images, sound files) so that they cannot be extracted from the app by a third party?

  2. How do you use the pvr.ccz with the Android part of the Cocos2d-x project?

Looking at some of the alternatives, there are a few developers who try scrambling the image assets so that they cannot be easily reused when forcibly obtained. Any suggestions?
