how do services like YouTube and Spotify encrypt their offline downloads?
In: Technology
The only way to read that particular file is to have the application on-hand to decode it for you. Plus, most offline downloads are only on mobile devices which would make it difficult for someone trying to decrypt the files to get to them. This is an example of where encryption doesn’t have to be perfect, it just has to be harder than some other option, such as using software to record the song.
