Cracking iTunes' DRM with JHymn

comforteagle writes "Howard Wen has interviewed 'FutureProof' of the JHymn project, a DRM removal application for iTunes song files laden, or 'crippled' as some say, to prevent filesharing. FutureProof tells us how Apple's DRM works, how to rip it out using JHymn, how they build on the work of 'DVD' Jon Johansen, and how to upgrade to that brand new iShuffle safely."

    When Hymn first came out (under a different name) they released iTunes 4.6 almost right away which would not see files that the old Hymn had converted - by recognizing one aspect of the converted files that was particular to Hymn generated files.

    Hymn released a fix in short order - I think back in July? It was a long time ago anyway. And since that time, Apple has done nothing to shut down project-hymn.org. And multiple releases of iTunes since then have done nothing to stop these files from playing - which it cannot do because they are now identical to files that you rip from CD yourself with AAC!!

    If Apple could or would do anything about Hymn, they would have done it by now.

    Since sales on ITMS have kept going up, no-one really cares if you can break the DRM or not.

    I'm not sure if Hymn still does it, but it used to even keep the ID of the owner in the file to make it impractical to share on P2P networks (as it could easily be traced back to the owner). I thougt that was a nice touch to show it really was not meant for piracy.

    I use Hymn myself, no to crack my master files but to break them so I can share them at work. The annoying thing about iTunes sharing is that if another user is not authorized to play a song it halts and brings up a dialogue, making true random play over another users library impractical. Once a co-worker and I even went so far as to authorize each others computer to play our music so that we could listen to the libraries of the other.

    I don't feel like using DRM cracks for this use is at all like P2P, since it's just streaming the song and not transferring it - plus lots of people discover music they might not have otherwise and it helps those artists out (which I feel P2P does as well, but it's a different and much greyer case).

  2. I'd like to think I'm not cracking anything here.. by nvrrobx · · Score: 3, Interesting

    I use this to remove the DRM from my legally purchased iTMS files so I can play them on my Phatbox in my car and on my Media Center PC. I'm not distributing them to friends, I'm just doing what I would have otherwise done by burning to CD then ripping back to HD.

    Probably still illegal nonetheless, but I really don't feel very 37331 when I do it.

    Half-Life 2 sold like crazy because it was probably the most overhyped game in recent times. It also was a good game to boot, but i know quite a few people who didn't buy it because of their hatred of Steam. And i'm one of them.

    It was pirated the same; in fact, there was a NO-STEAM a day after release. So you could argue it was less of a hassle for pirates to play it than it was for some users from what i've read :)

    No per-track at all. A flat-rate or collective license model would work. The collective-license model would work best, since in that case, they could simply allow P2P to operate legally. The users would, in that case, absorb the costs of bandwidth, distribution, and manufacturing of the CD's if desired. All the labels would have to do is sit back and collect the money.

    Of course, given that, they could no longer -control- distribution. Might that be the reason for the resistance to something which in every other way is pure profit for them?

    However, a flat-rate model would also work. And I'm not talking "RealRhapsody"-I'm talking a per-month flatrate for downloadable, burnable, DRM-free content, with EVERYTHING available, not just whatever few labels they can get to sign on, in (within reason) a format of choice-perhaps choices between .mp3, .flac, .ogg, and a raw uncompressed format.

    When they offer that (provided the fee isn't astronomical), I'll have my credit card ready. Until then, I'll keep right on downloading. And by the way, guys-DRM is trivial to break.

    • Isn't it retarded that we have to crack DRM anyway?

    This isn't flamebait - it's true. DRM costs money - removing it generates revenue. Counterintuitive? Case in point:

    An iBook came into my household this christmas. I had heard about iTunes for years, but not being on Windows or Mac, had never seen more than a screenshot. So anyway, I try it out and buy an album I once had but lost to a departing girlfriend. It was cool, but I also knew it was DRMed - and indeed, when trying the file on my linux box - no joy. I didn't buy any more music after that. No way would I pay for music I can only listen to on one computer (I want it to work at home (linux/new mac), work (linux), studio (linux)). So I didn't buy any more music - then I heard about Jhymn - installed it, stripped the DRM off my files, txr over to my linux box, and voila - lot's of joy.

    That was about a week ago - I've spent over $30 on iTunes in short time since then (it's frighteningly addictive and easy to click "buy" - especially when sleepy late late at night). Without DRM stripping I would have spent a big fat ZERO.

    Moral of the story:I only buy from iTunes BECAUSE I'm able to strip the DRM and play the files on my linux boxes ... a fair use I believe because I can only listen to music on one computer at a time.
