Hello all,

So recently I've become very interested with this whole idea of decryption and how it works and what not. So while using spotify I found the location of all saved music and I was interested in learning how they encrypt it.

Ok so if you've even gotten this far you're probably thinking "wow, who is this idiot. he knows nothing." Well - yes, that is completely true. I've had some php background and i dabbled in the hex editing of COD for a small amount of time.

So here is my question. What do you suggest I start with on learning how this encryption works, and also, how to figure out what sort of encryption something uses.

Any suggestions / yelling at me for how n00b i am, is more than welcome.

From the look of it its broken into lots of tiny block files. Probably streams and downloads in block, to prevent lag. I believe Spotify joins those files through some decryption and decompression. The file is definitely encrypted and probably compressed based on the sizes.

You can use Spotify offline though, so the idea of an "online key" to decompress the files is out. You could try and peak at Spotify by that probably won't get you anywhere. For the millions of record companies that licensed Spotify, they must of had a helluva security system to show off to them. Otherwise no one would allow their music on it

I think they spent a good deal of time figuring this out. I'd say its pretty secure. Still nothing stops you from using Audacity "record what I hear" and it records from whatever your sound card is playing. So run that, then play a song. Boom MP3 of that song.

I'd look into this: http://despotify.se/
It's the open source Spotify client + library.

thanks for the despotify suggestion, I saw that as I was browsing google.

Do you have any suggestions as to how i can learn how to decrypt things?

there you go for any song you want....

is stealing music still hard ?

haha, I know how to get music. I'm not currently interested in how to get free music. I just want to know how encryption works and I threw out an idea on a current encryption that I was interested in. Thanks though
