python - obfuscating distributed text/image/sound files

In distributing开发者_开发知识库 my app, I'd like to prevent casual users from viewing my png files, playing my mp3s or reading/modifying the plain text files I use to load and store data. The text I guess could be binary pickled? What about the images/sounds? What do you do when distributing your app?

Assuming py2exe or py2app.

You can use zip files, but they'll be visible while the program is running; you could extract them to a run-time generated temporary directory with tempfile.mkdtemp(), but it still would not be difficult to track them down.

Another solution would be to use a light-weight encryption, or even simple obfuscation (such as ROT13 for the text files, and a simple xor cipher on the binary files). This will add some time to the execution of your program, so make sure and take that into account.

You could archive those files and at runtime unarchive, use, then delete them:

Not a very strong protection method, but it will discourage hobby hackers
