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."
At this point, I've decided to get out of the game. No IRC-crawling, no Kazaa, no DRM-breaking.
It's much easier to use the five-finger discount.
I hope stuff like this teaches companies no one wins with DRM. Not themselves, as they're made look incompetent when DRM is cracked ("Protected CDs" rippeable pressing CTRL?), and certainly not their customers.
If it's digital, and the end user can see / hear it, it can be copied. Perfectly. Deal with it, and make it interesting to buy instead of pirating.
'If you encrypt it, they will come...'
HA! I just wasted some of your bandwidth with a frivolous sig!
Admittedly, without the thrill of "fighting the man", but in this case "the man" is giving you virtually everything you asked for (inexpensive music you can try before you buy with the ability to download exactly what you want and make mix CDs, which you could then rip as well without needing this tool.) Now Apple is going to have to crack down again.
What does this win us? The music industry can point to this as another example of why the restrictions need to be in the hardware and the hardware manufacturers are already in their pocket as far as the next generation of motherboards are concerned. Thanks to the pirates, those of us who buy the stuff again have to pay with further restrictions.
Try not. Do or do not, there is no try.

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).

I love folks complaining about "crippled" iTunes songs.
They forget that Apple has SET THE STANDARD for sensible DRM that is reasonable for the consumer.
I've been around a long time, and have seen plenty of stupid stuff. Divx (in the DVD space) moved things back, lawsuits and claims about the mp3 format itself, a joke.
But I've also got a sense of history. Before apple came along legal online music was GHASTLY.
You think iTunes is "laden" and "crippled" with DRM? People have forgotten that before apple came along there was a fragmented music space with DRM that meant you couldn't move songs between computers, burn them to CD's, and stores run by companies that were no fun to do business with. Subs, if you canceled, your music vanished.
For most folks, fairplay is actually fair. Most people don't end up playing on more then five computers. Unlimited burns of a song, and seven burns of a specific CD are reasonably fair. The authorization process isn't terribly painful.
Remember, the RIAA used to claim on their dumb soundbyting site that making a tape copy of a CD was copyright infringment. And they were probably right, it was.
The one big issues with iTunes are lack of open source support (tricky, but they should do better here) and the lock-in to iPods as the portable music player for the service. The issue is that software needs to provide the DRM. Luckily for apple they've got a reasonable ipod product. This lockin will have to evolve though of course, open source and linux are not supported so far.
But from a DRM perspective, they really moved the industry forward. If the media companies had their way we'd be stuck with Sony's ATRAC format.
So, complaints and props to apple.
If you give up control, you get what you deserve.

Now if Apple licensed Fairplay playback to device manufactures and software developers, that might change people's opinion but as it stands now, Apple computer has a monopoly of fairplay enabled music playback. I would suggest that Apple open Fairplay, but as we all know, the concept of DRM is simply PKI turned upside down. Its a game of digital hide and seek or "security by obscurity," so it is simply not possible to open source any software based DRM scheme.
Lets look at this situation from another angle, if Microsoft was the leading online music retailer and used a format that could only be played back on Microsoft hardware and software products, would people be defending them? The hypocrisy and denial of Apple fanboys on /. is so blatant, its not even amusing anymore.
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
What changed under Obama? Nothing Good
FutureProof said that Apple is putting watermarking in their music and they are looking for the lack of that watermark in future versions of iTunes (both to stop competitors and most likely identify those who would rip from iTunes and resell it illegally). Nothing has stated that the watermark is an Apple-wide watermark (i.e. distributed to all users) or if it is a per user watermark added on top of the Apple watermark (double water-marked).
Unless this makes your head swim, there is an excellent book that most folks with a bachelor's degree in some field which involved math should be able to read and understand: Information Hiding Techniques - Techniques for Steganography and Digital Watermarking (ISBN 1-580-53035-4), by Katzenbeisse. This and some other related books can been seen at forensics.nl.
