I want to build an iPhone app which is doing the following thing:
1. in the app will be a mp3 file encrypted using AES 128 or RC4 (preferred)
2. the file must be played using AVPlayer or AVAudioPlayer (other solution also accepted if we discuss this together)
3. the encrypted file must be on the fly played (that means no extraction on the harddisk before play)
If you have experience or demo in doing this you will win the bid.
I attached a file with the key and the encoded audio file. The coder with a demo playing this file is going to win the bid.
The sample audio above is encrypted using RC4.
