播放加密的mp3文件

Question

I am currently trying to play a encrypted .mp3 file. The way I am currently using is:

loading the encrypted file -> decrypting it -> save it to ISO -> play it with the backgroundaudioplayer .

But this can take up to 10-15 seconds to start one .mp3 file. Is there any other way to do this faster ? For example is there a way to play from a stream and somehow decrypt it while playing ?

And is there actually the need for encrypting the files on the IsolatedStorage ? Since nobody should be able to touch them anyways ?!

好吧，因为它已经使用了很长时间了，所以我建议“缓冲”它的确很简单，让解密流从文件的前20秒左右为您提供一个大小合适的缓冲区，这应该比等待最多快几秒钟。整个文件，然后只需使用解密的缓冲区简单地将backgroundplayer送入，其余的仍在解密。
