encryption - How can I store music on an android phone without allowing the user to be able to download it and use it? -

-

I am working on an app that connects to the site that provides the site and the MP3 files in the user's phone Downloads I want users to be unable to copy these files from the phone, but only listen to them through my app.

I am currently trying to encrypt the files and decrypt the files using DES and encryption in the bits in the app though this is not working. Is there a better way to achieve my ultimate goal or is there a solution similar to that of someone else?

if you ds (A private key or symmetric-key algorithm), then you need to store the decryption key in your app. Remember that this is a byte code by Android, it is easy to separate to retrieve the key.

Think about the other.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
