I thing FreeMe's docs mention such a proggie, try it. The sad fact, however, is that there cound be a minimal loss of quality when using compression. But, as said, it is minimal.
chemman	Subject: Re: Re: DRM protection! How do I get around it Date: April 7, 2004 @ 11:12 AM goldenapi - the key, downloaded by the player, should have some basic info that only the downloading computer can have. Perhaps it records the IP, windows's serial, or perhaps that unique code written somewhere in the motherboard?

chemman	Subject: Re: Re: DRM protection! How do I get around it Date: April 11, 2004 @ 9:45 AM Brute force seems to be more and more tempting. Especially when I have access to a 4-processor 2200 Mhz server and will have the possibility to test it. Code donations would be appreciated. >:- >
goldenpi	Subject: Re: Re: DRM protection! How do I get around it Date: April 12, 2004 @ 5:06 AM Ive been meaning to construct a brute force monster-box, but dont have the money Code donations would also be appresiated here. But MS-DRM uses EEC at anything from 40 (export thing) to 256 bit, so that could take some time. You can try, but I dont know how long it will take. With your hardware, anything from weeks to years. If there are any coders here, could you make it a distributed program (seti-like would be ideal). That would allow anyone to build a decryptor from common hardware, instead of fighting to make multiprocessor boards cooperate. Capture. Audio, easy, plenty of programs can do a loopback record. Its the video thats going to be a problem. The only way I have been able to crack a DRM-WMV is to play it on one of my computers while using the video capture card in the other. But there is considerable loss of quality. The key for each file is random. The computer-specific info is in the licence, which also holds the key. But the licence is heavily tamper-protected, and is itsself encrypted so you cant just get the key out. MS-DRM is the most sophisticated PC-based DRM system on the market.
chemman	Subject: Re: Re: DRM protection! How do I get around it Date: April 12, 2004 @ 9:03 AM Nice to know that. Actually, I'm a programmer, but it would be almost impossible for me to design a distributed computing network alone. Plus, I'm not an expert when it comes to encryption.
goldenpi	Subject: Re: Re: DRM protection! How do I get around it Date: April 13, 2004 @ 7:49 AM Im a poor programer. I would have thought the distributed part would be easy. Divide the task into key ranges, make a server to keep track of which ranges are done, and just have clients contact the server to request a range, check the range, and report back to the server. Just like seti. Even I could do that. But the decryption part, I wouldn't know where to start. I can use crypto, but im no expert. I know just enough to understand the 40-bit export-level files are easily brute forceable, the 56 bit need a huge amount of processing power, and anything above that is unfeasable. Of course, much of the demand for WMV cracking seems to concentrate on porn sites that cant afford the good encryption

goldenpi	Subject: Re: Re: DRM protection! How do I get around it Date: May 15, 2004 @ 5:29 PM You dont have the licence. The entire point of WMDRM is to keep the licence seperate from the main file, so even if the file itsself is traded over p2p the licence is not. Most likely, someone was sharing that file without realising it was DRMed. As for the keys, WMDRM has many of those. There are file encryption keys, licence encryption keys, server authentification keys, the legendry master keys, the system-specific blackbox key, the HW-derived key....
Hawking	Subject: Re: Re: DRM protection! How do I get around it Date: May 20, 2004 @ 5:24 PM I'v been thinking about this problem also and have come to an idea... I say get a .WMV DRM file that you dont have a license for and open it up in a program like winhex, open another .wmv file that doesnt have DRM on it and delete the coding of DRM on the file... but I'v tried that but it crashed my 1.6GZ comp (tried to open a 332mb file in winhex) also in winhex, it says its title name and other info... so try to compare, and mybe rename both files to same name... and if this helps out at all Iv heard the license info is in the header of the file... well if any of you can find a way to delete the coding pls reply.
goldenpi	Subject: Re: Re: DRM protection! How do I get around it Date: May 20, 2004 @ 5:32 PM You cant delete the coding. You think Microsoft would make it that easy? The content itsself is encrypted. The DRM header in the file doesn't contain the keys to decrypt that. It contains a reference to the licence, and an optional link to a website for obtaining the licence. The key for accessing the content is stored seperately in the licence, which is encrypted and signed to prevent tampering. This license also holds the usage rules, expiration date, etc.

erldammit	Subject: Re: Re: DRM protection! How do I get around it Date: May 21, 2004 @ 6:26 PM I paid to download a .wmv file a couple days ago. I read these posts, and I'm assuming that that they would be using the newer DRM, since the file is brand new (it's a baseball game from this week). I'd like to be able to burn it to DVD, if possible, but if not I can just watch on my computer. I downloaded FreeMe, but was unable to figure it out. And I'm not sure if that will even work. Since I have the original license on my computer, and activated the license via their URL, what are my options? It'd be great to get rid of this pesky license. Please let me know of your thoughts.
goldenpi	Subject: Re: Re: DRM protection! How do I get around it Date: May 23, 2004 @ 5:44 AM No, noone uses the newer DRM. WMDRM comes in two versions, DRMv1 and DRMv2. Shortly after DRMv2 was released, before most companies had switched to it, the FreeMe decryptor completly destroyed it. So companies refuse to use it, instead using the older DRMv1 system. The only major difference is the way usage rules are specified. DRMv2 is a bit more flexible. Converting a DRMv1 video file is very difficult. *Very* difficult. Only WMP is able to open the file, and that cant export it. Its layered with anti-tamper systems. Personally, I would just play it on one computer and run the outout to a video capture card on another. I can do an all-digital conversion as well, it involves a trick with VMware, but it requires a huge amount of processing power, in the region of a 3GHz chip. Neither technique is possible for someone with only average hardware. DRMv1 on video is one of the few systems that hasn't been completly broken. Audio is easy, but not video.

Thet are WMA 9, DRM protected files. I have tried a ton of crap to record or convert this junk. Un*uck.exe and Freeme.exe don't work on WMA 9. Freeme is definately a good place to start if we have any interested C programmers who would like to pick it up. It includes source code. Micro$oft has increased the size of the encryption code with WMA 9. I sent Buymusic the following e-mail: Dear Snot Rag Industries, I have been unable to burn these files to an audio cd. This was, and is, my only purpose for downloading this music. I have spent several days merely attempting to get this junk to.. A. Play and B. Copy. After I finally had to step through a process of individually registering each of these tracks (14) one at a time, The entire process is now lost due to a software removal and installation process. I upgraded to Nero 6.0 from 5.0 in order to copy this and in the process my, previously initialized files, are now de-initialized. Nothing works. What Possible use do I have for this Junk! They are flatline; they are all dead. Either A. stop wasting my time and make this crap work! or B. Credit a refund to my account. At this point I am so disgusted with You and Your DAMN WMA JUNK that I don't give a damn! SERIOUSLY PISSED OFF! Me Their Reply: Thank you for contacting buy.com.

I managed to get the files to play again by reinstalling the WMA Codec (Wma Audio Codec.exe Ver. 4.00.0.3845). Attempting to play and simultaneously record to wave caused enumerable system problems. This included Windows removing my CD copy software Adaptec drivers. Here is a way to get your files to wave. It's not pretty but it works. You will need. a second PC ( A Notebook is ideal ). An audio cable with a mini din connector on each end ( About $2.00 ). Wave recording software installed on the second PC. I used ALL2Wave (Free Internet Download). Set up the wave recording software to record from audio in (Microphone), Stereo input at a high bit rate and frequency to get a quality file. Connect the audio cable to the Speaker (Audio Out) connector on the main PC's sound card and to the audio in (Microphone) jack on the second PC. Play the files one at a time using Media Player, WinAmp, JetAudo or whatever you use, while simultaneously recording and saving the wave files on the second PC. Once you have the files in wave format convert them to MP3 and post them on Limewire, Kazza and Morpheous!!! P.S.

Musicscom	Subject: Re: Re: DRM protection! How do I get around it Date: August 15, 2004 @ 2:24 AM See why their record sales are falling? Play your computer songs into a cassette player while recording. This gets rid of the code by changing everything to analogue first, then back to digital when you re-record it to your computer. As an author and recording artist, I am totally against this secret encoding crap. It only hurts the artist. We expect people to make copies you boneheads! Boycott buymusic itunes and the others.

goldenpi	Subject: Re: Re: DRM protection! How do I get around it Date: August 15, 2004 @ 5:06 AM ImaGeek: That is known as the 'analog hole' method. It is the easiest way to break most DRM systems, and works on all audio files, but has flaws. Firstly, it needs equipment. Even if the user has two computers, they still have the inconvenience of buying a cable. Secondly, through making a copy is easy, making a copy properly is not. You did not us the correct procedure, so your files will be less than optimal quality. Firstly, you input through the microphone input rather than line in. Microphone inputs have a DC bias intended to power condensor or active mics. Secondly, you did not set your recording level correctly. That will result in either clipping (level too high) or a reduced volume file (level too low), which will stand out in a playlist.
ImaGeek	Subject: Re: Re: DRM protection! How do I get around it Date: August 15, 2004 @ 12:30 PM goldenpi, You are correct. It should be line-in, which is what i used. Yes it is a pain in the butt, but then again, there really is no good solution. You can get good quality. You should adjust your output file volume for your files etc, and make some short test tracks before recording the whole shooting match. If everybody knows about this, how come I didn't find it here? The subject here is, "How do I get around DRM protection ?". For now, this is the best we have. LOL
goldenpi	Subject: Re: Re: DRM protection! How do I get around it Date: August 17, 2004 @ 4:44 AM Because its not the best we have. There are better ways, but they all require either rare equipment (such as S/PDIF or Toslink compatable sound cards) or a great deal of skill (Emulation attacks). Analog hole attacks are slow, easy to do badly and always cause some loss of quality. Quite a lot with a cheap recording sound card. There are only two advantages to this technique: It works on all audio DRM systems, and the procedure is not too difficult. I shall produce a tutorial on the correct application of re-record analog hole attacks for my website.

goldenpi	Subject: Re: Re: DRM protection! How do I get around it Date: February 3, 2005 @ 2:38 AM No, too easy - its more complicated. The WMV file is encrypted - to play it you need the key. The file also contains a pointer to the licence-file, which contains this key. The license file is itsself encrypted (you dont have it anyway), and only WMP contains the key to decrypt it - layered in tamperproofing.
Marco255	Subject: Re: Re: DRM protection! How do I get around it Date: February 4, 2005 @ 7:33 AM I imagine if one would write a virtual sound driver to dump audio output to a file one could sort of rip anything. Of course you need to be able to play it in the first place though, which would be the problem.
freemesucks	Subject: Re: Re: DRM protection! How do I get around it Date: February 5, 2005 @ 3:15 PM No additional hardware whatsoever is required. All you need is Winamp, and a cracked in_wm.dll file which you can obtain from astalavista.com by searching for DRM. You also need a good MP3 encoding utlity such as Cyberlink MP3 Encoder, whose serial is also available online. Use 128 kbps as the output format. As long as you have a decent computer, there is no noticeable loss in quality. Yes, there is a loss of the tags but it shouldn't be hard to come up with a utility to take care of that, at least partially. In the next few days I will try to post a link to a PDF file which explains these steps in detail, although that really shouldn't be necessary.
goldenpi	Subject: Re: Re: DRM protection! How do I get around it Date: February 5, 2005 @ 3:56 PM Loopback driver recording. Old trick, but effective in most cases. Marco is right though - if you cant play the file, its useless. MS did come up with the idea of "secure audio path" to correct that potential attack - it checks the cards drivers against a list of cryptographicly-signed permitted, trusted drivers. Its not used much, due to serious compatability problems. It has caused a few minor issues for those with digital-connection speakers though - it assumes all digital outputs are untrusted and disables them.

Riaa1sucks	Subject: Re: Re: DRM protection! How do I get around it Date: February 8, 2005 @ 6:04 PM COOL PROGRAM TO GET AROUND WMA DRM: so i recently found TuneBite. Basically, it plays a song (can be DRM protected) and it uses your sound card (or you run a cable from your line out to the line in) to record whatever's playing and it makes another file that's encoded in OGG or MP3 to a destination of your choice. It also renames the new file to the same name as the previous file so you don't hafta go back and type the artist/song back in. Only downfall is that it encodes at 1X but hey, for $12, I say its a handy tool. I've found that the quality of the recorded file at 192KBPS sampling is great. get it at: http://www.tunebite.com/index.php?affiliate=1003
Riaa1sucks	Subject: Re: Re: DRM protection! How do I get around it Date: February 8, 2005 @ 6:06 PM BTW, use with Napster's service and you can get A LOT of new music after d/l.g the files to your computer =)
freemesucks	Subject: Re: Re: DRM protection! How do I get around it Date: February 9, 2005 @ 1:11 AM The quality of Napster's WMA songs is 128 kbps. It would be a waste of storage and also misleading to set the output to anything above 128 kbps.
freemesucks	Subject: Re: Re: DRM protection! How do I get around it Date: February 9, 2005 @ 2:06 AM [The above statement is true only with the assumption that WMA encoding is only very slightly better than that of a good MP3 encoder, and that slight difference can be ignored.]
freemesucks	Subject: Re: Re: DRM protection! How do I get around it Date: February 9, 2005 @ 3:11 AM Tunebite 1.1.0.3 Review: [Search for tunebite at http://astalavista.box.sk for keygen.] [If needed, a stable lame codec can be obtained from http://www.rarewares.org/mp3.html ] Tunebite presents one major advantage over the previously mentioned cracked Winamp technique - it copies over all of the tags to the output files. Output to MP3 format was found to be buggy. These bugs include incorrect notation of output bitrate and length in the output file. It is generally pretty important to know how long the song is, so I consider this a serious bug. Output to OGG format, however, seems flawless, and does not have the above mentioned bugs. The only reason I can think of why someone would not want to output to OGG format is that few portable and car music players support it - this again is pretty serious. In conclusion, I would say that if the OGG format is okay for you, go with Tunebite, or else go with the previously mentioned cracked Winamp technique if your content is going to expire soon. If you can wait a few months before your content expires, I'd say try waiting until perhaps the bugs in Tunebite get fixed. Any one have any other thoughts on this?
domology	Subject: Re: Re: DRM protection! How do I get around it Date: March 8, 2005 @ 2:40 PM Hi all. I have a couple of CDs that are "copy protected and pre-ripped for pc". I'm really annoyed that I can't put them on my mp3 player. I tried IsoBuster and this didn't work. Is there anything else I can try? thanks in advance.
goldenpi	Subject: Re: Re: DRM protection! How do I get around it Date: March 19, 2005 @ 8:53 AM Oh, copy-protected CDs. Yes, those are breakable. The method needed depends on the protection system used - the early ones could be broken using a pen, but that doesn't often work now. The most reliable methods require expensive equipment or great skill. But there are some very simple things you can try that sometimes work. First, use cloneCD to make an image of the CD, mount that in clonedrive and then use your CD-ripper of choice on this. I dont know exactly how this works, all logic says it shouldn't, but it defeated a CDS-protected CD I used for testing. It cant hurt to try it anyway. Dont even try decrypting those ready-ripped tracks. Those are tough - the weak point is still the CD-audio sessions.
domology	Subject: Re: Re: DRM protection! How do I get around it Date: March 20, 2005 @ 7:47 AM I just tried cloneCD and it came out with the same result. Is there anything else I can try or will I have to resort to recording?
freonpsandoz	Subject: Re: DRM protection! How do I get around it Date: March 25, 2005 @ 1:40 AM If you can play the DRM protected file in Winamp or WMP under Windows 2000, a program called "Virtual Audio Cable" can be used to route the digital audio to a recorder application such as All2Wave or CoolEdit. (Tech info: VAC uses a driver to accomplish this and, as goldenpi mentioned above, a DRM certificate can require all drivers to be DRM certified. But I don't think any do yet because W2K doesn't support driver DRM certification and an unknown number of existing sound card drivers out there are still uncertified.)
