Isn't this kind of what iTunes already does? And the program that decrypts it just uses the private key that you need to have in order to use your purchase!

Of course it hasn't been updated for the latest version of iTunes, but I believe that was due to lack of interest and the fact that you can still downgrade iTunes and use it there.
