(If you’re in a hurry, see at the very end for a quick list of all useful software and video tutorials)
JDownloader is an open source download manager, primarily aimed at downloading from captcha-protected download sites (RapidShare, Megaupload, Hotfile, Netload…) but supporting also any “normal” download (like a picture from photobucket, or actually any file from any server).
Although claiming to be open source (and actually, it’s currently under the GNU GPL), parts of it are close source. Notably because they rely on an undisclosed encryption algorithm for their encrypted links list files. I’ve never understood the point of making those lists undecipherable, particularly since anyone is able to open such a list with JDowloader and to grab the files. Only they won’t be able to easily get the location of those files.
Anyway, there are several easy ways to find the links inside a DLC:
- The always-working method: JDownloader will never be able to prevent you from using this method, as this would require the complicity of hosters. Basically, this method involves to simply spy your own connection and record what URLs are retrieved by JDownloader. When you load a DLC links list, JDownloader will check if the files are online. With any packet sniffer you can list those links. A more detailed short video tutorial was posted on sala source. Just in case this goes offline (as other DLC decrypters have), I mirrored their video on Megaupload there [http://www.megaupload.com/?d=TJ85M6AX] (tip: if you want to save download wait time, don’t download it yet but rather watch it live on megavideo [http://www.megavideo.com/?d=TJ85M6AX]) and their toolkit too [http://www.megaupload.com/?d=BRTD1GNI].
- The easier method, but probably not working with recent DLC files (JDownloader tend to change their encryption method regularly to avoid decrypters): a decrypter made by Seba. It was originally posted on a BlogSpot blog but eventually disappeared. But thanks to FilesTube I still managed to find it and I uploaded it here [http://www.megaupload.com/?d=26FVJVN1]. It was created around May 2009, so it should work with DLC files created before this date, and possibly during some time after. I didn’t test it with current DLC files.
For a short summary:
- DLC Decrypter version 0.7 (May 2009) by Seba (broken link, used to point to http://www.megaupload.com/?d=26FVJVN1)
- Video tutorial [http://www.megaupload.com/?d=TJ85M6AX] that (normally should) always works, and the tools [http://www.megaupload.com/?d=BRTD1GNI] that go with it
Update (2011-03-27): online DLC decrypter
As you can see from the comments, every now and then some DLC decryption sites pop up then go. Well, I think I’ve found a pretty “stable” one, or at least one which has been maintained for around 9 months now. I just tested it, and it works for the moment. It’s a bit slow, so I wouldn’t be too surprised if their inner workings were just like the “always working” method I described above: run jDownloader and analyze its network traffic! (which would mean a very high probability of remaining online as long as the owner wishes to) Or of course maybe it just means they’re on a slow server, eh… 😀 The site is dcrypt.it
Update (2011-04-17): offline DLC/CCF/RSDF decrypter
As you can see from the comments, the decrypter “by Seba” is actually developed by a company which still updates it. The current version seems to be 1.7.0.0 (the one in Seba’s pack is only 0.7) so it’s probably worth the upgrade… if you manage to run the installer (it failed to install on my Windows 7 x64, which is why I’m not exactly sure of the current version number). Their website: containerex.info
Update (2011-10-27): another online decrypter
linkdecrypter.com offers pretty much the same functions as dcrypt.it, so those 2 are pretty much interchangeable should one of them be temporarily unavailable.
Update (2012-01-31): files stolen by the FBI
As you most likely know, Megaupload was shut down by the FBI without any prior notice. Some files I linked to were hosted there without any backup… so, broken links now I guess 🙁 On the plus side, the online tools as well as the self-hosted containerex.info work just as well (better indeed) as the things I hosted on Megaupload. As a memorial (and maybe in case there’s a way to get those files back), I’m leaving the original MU URLs in plain-text next to the former links.
hey, I hacked together a little web app to do this too
check out
Http://www.decryptdlc.info(note on 2011-02-23: comment edited to remove the link as the site seems permanently down)
Actually, I think it might be blocked at the moment, working sporadically
I guess a web app will always be vulnerable to this. oh well
gracias mjonson, justo lo que estaba buscando excelente.
No need to install a program:
Http://www.decontainer.infodoes it for you.Well, actually the files which are listed here all don’t need to be installed. On the opposite, this decontainer.info website requires the installation of *cough* M$ Silverlight (which of course won’t work in Firefox)
It does work, you just have to restart FF if you have not got FF 3.5 or above i think.
Silverlight is like flash and more and more sites are adopting it…
Hm… then maybe it’s because I’m on 3.6 beta. Installation hangs at the beginning, after:
“One moment, please, while the current Silverlight installation status is determined…
Microsoft Silverlight may not be supported on this browser.”
Both the method posted here and the online services are not working
I suppose they updated the DLC encryption then. Yet the “always-working” method still works 😀 If you have trouble with their toolkit, you could try with something like WireShark instead.
Silverlight needs to just die and give up … YUCK! Microsucks can take a hike really… they haven’t produced anything decent since windoze 98.
surprised anyone techie enough to put together a DLC decryption website would use crappy M$ stuff! UBUNTU! Or even Leopard for that matter! I mean my god, how many licks does it take to get Internet Explorer right? Apparently none, cuz it’ll never be right!
Thanks anyway, always appreciate people putting up their work like that, just too bad most people won’t use it due to silverlight.
Actually, unfortunately I’m not sure many ppl really mind installing Silverlight 🙁 It’s like Vista and Seven, it’s all flash no substance but basic consumers love the shiny look, even when performances are poor. I recently checked a friend’s laptop, Seven took ages to load because she had 1.4 GiB of RAM getting filled at start up with various junk (MSN, SKype, etc) – it was so much junk that it created a conflict with sound playback (it turned out the culprit was Skype). But I’m getting off topic, eh 😀
@patheticcockroach is correct. Why would anyone sane install Silverlight at all? Sorry dude, but I don’t think you’ll be seeing intelligent life forms visiting your site. You might get some using Vista/Seven + I.E., but then again, those people do not classify as “intelligent life forms”
Wow, are you guys really that arrogant? OMFGLINUXISGAWDLOLOLOL
Get a life. Not everything revolves around some idiots getting together and trying to use for-server OS as actual user OS. I have no problem with 7. In fact, it’s faster, not to mention better, than XP ever was, which was faster than ‘windoze 98’ could ever hope to be.
Of course, if you’re running a crap laptop with a billion programs loading on startup . . . um, what do you actually expect to happen? You can’t possibly think of blaming an OS for doing what it’s told. That’s just ignorant.
@Whatever:
1. Nobody before you talked about Linux in this thread.
2. You make me realize that I forgot to mention one thing in my last comment about this friend who had a very slow start-up: she we was still happy with it, “because it looks good” (hence my “basic consumers love the shiny look, even when performances are poor”).
3. Are you also going to pretend that XP is faster than 3.1? Se7en is only interesting because Microsoft didn’t want to add some features to XP. Mainly: a well-promoted 64 bits version, Dx11, support for more hardware by default. Also about the speed, you waste tons of time with this UAC crap (or end up deactivating it): Se7en is like “XP with extra Linux annoyances” (and with 4 times the RAM usage on a clean install).
Consider that if you see, advertised, an online web app that decodes dlc information
that’s an easy way for the operator to find dlc applications.
eg.
Here’s a great link just input the url of the dlc and it will decode it.
end–
Thus is MS owns the decoder site it’s gonna kill that url fast. duh.
dlc container by seba contains virus
If you’re talking about the executable, it’s a false positive. If you’re talking about the rest, well, I didn’t check where the links point to but they’re useless anyway.
However, strangely enough I missed a very important thing about this package: the software it contains is developed by a company which still exists! So it still receives updates: http://containerex.info (the version in the package is 0.7 while the current version is at least 1.7.0.0!). So, long story short: you should grab the latest version from that site rather than the outdated version here.
Thanks for the great info about DLC file decryption! Good stuff!
that containerex is so slow…do i need to have 5Mbps connection? 🙁
I don’t know… I don’t think so, why would it require some specific connection speed?
http://linkdecrypter.com works great
Great, yet another one 🙂 Thanks!
Kind of ironic that you uploaded the tools to megaupload.
LOL
Hahaha… I see nothing funny in the FBI stealing people’s property…
Thankyou! I was looking all over for something to do this.
JDownloader is the worst experience i have ever had with a program, i would rather download the files manually. Thanks again for the decryptor site it worked like a wonder 🙂
Actually, I find that jDownloader is okay (except that it’s so terribly slow as hell, feels like loading Java 10 times in a row), it’s the smart-asses who encrypt their links for no reason who aren’t…
Very Thanks My Friends.
thanks it works
