I have a website in which I want to sell sound files. I want a simple bespoke media player that will play encrypted flac files. The encrypted flac files will embed a pdf which will display sleeve notes in the media player. Additionally, I want the media player to have internet connectivity so that users can play only the sound files paid for - I'm not sure how this can be implemented.
As well as the media player I need a simple interface for encrypting the flac and pdf files.
