[X] My Assistant

Hi genl

I'm just wondering if you're still able to do "CypherGuard for Movie" files from DL Site.
I generally avoid buying DRM'd stuff, but if I can view it without having install such junkware, I'm interested.

If you are still doing this great service, I was also wondering:
-For such movies, what format does it come out as? The DL size according to the site is 2GB+ for a 25min movie
-Given the size, is there a particular filehoster you prefer?
-When you ask for login:password, is this our DLSite password, or is there a separate password to unlock purchases?

Thanks!

I've only been able to extract images from Keyring PDFs by freezing the PDF-viewer and/or DRM process with Process Explorer and press print screen or use a third party screen capturer. Unfortunately that means I can't get higher resolution than 1200x1920.

If someone wants to use screen capture, I suggest to only do so if the following conditions are met:
1. You have enough time to process each page this way.
2. You don't care about possibly inflated filesize of resulting images.
3. You can reliably capture pages fully at their original resolution at 100% zoom.
4. You never save captured data as JPEG. Use 24-bit PNG for 24-bit data and 8-bit PNG for b/w 8-bit data.

When the source is PDF, you may never meet the (3) condition, due to how PDF format works and how Adobe Reader is dealing with the scaling.
If something goes wrong, you end up with issues like cropped edges, upscaled or downscaled images. Tearing if each page needs several captures and you are not careful enough. Additional compression artifacts if you save as JPEG.

Looks like CypherGuard has amped up their protection. Suspending the process no longer works for me.

+ Toranoana E-books.

This one is rather strange. Nothing to decrypt here, but there are circumstances:
1. Original images are kept as JPEG, and they are scrambled. It's impossible to unscramble them while keeping both original quality and original file size. This is one of reasons why I've never tried doing anything about such E-book protection.
2. There is something wrong going on with the E-book viewer script or its rendering part (a bug in all latest browsers is also possible but unlikely). Images are not getting properly unscrambled. Something makes the pieces shift vertically by 1 pixel, causing a defect in the output, visible to the naked eye (see the comparison between screen capture and intended output below). An online E-book viewer which is not even capable of displaying images in original intended quality is quite bad. This is one of reasons why I've started working on this.



For processing Toranoana E-books, I must have either login:password for the library area or a session key. Session key is just a long string and it expires in ~1 minute, so if you want to go this way, we'll need to meet online, for which I suggest IRC or TOX (will post more details later, for now you can PM me). The result will be saved as PNG files, with greyscale pages converted to 8-bit PNG.

I will consider sharing the unscrambling script with someone who intends to process such e-books regularly.

Hi genl.
Could you expose the method of ripping .dmme files? Is it complicated or you want to keep it a trade secret? I know how to use viewerrip but can't deal with .dmme files. Maybe you are kind to tell me how?
ps. DMM started to scramble online images.

I can't offer any better method than doing this myself at this time (decryption though, not ripping). It's not very complicated if you have right experience in debugging and coding. But I expect any capable person to also understand my reasons for keeping it out of public (huge portals wouldn't like such things). viewerrip is irrelevant (screen capture vs. decryption) but I guess someone may expand it with support for newer formats.
As for scrambling, I haven't seen that scheme on DMM yet. I'd look at it if someone has a sample.

I think that we can tell the bloke that the trick is not about bruteforcing encryption but about getting around the pieces of the application that attempt to lock you out from the decrypted data.

In other words between the decrypted file in memory inside the DMM application and your screen there is quite a lot happening (e.g. screen raster updates and window positioning). The DMM application tries hard to close al many channels into those operations as it can but due to the fact that there are many, many channels it fails to protect some of them.

P.S. I have no clue about the DMM application. But that is the general design in fooling an app that shows you "encrypted" data. And the exact trick that genl found is completely up to him.

Understood. guess i had to use screenshot for compromise.

I stumbled on this forum looking for ways to crack these protected games I purchased from dlsite. I just wanna be able to use text hookers so I can play the game. (IMG:[invalid] style_emoticons/default/dry.gif) Because of the "dlsite secure application kicker" (EISYS,inc) DRM, that's not possible. If you can help, I would appreciate it.

Yes, things like text hookers may be less compatible with games protected with specific DRM. If you know for sure that it should work with the engine your game uses, it'll probably work fine with cracked version of the game. If you PM me the game file and login details, I'll remove the DRM and send the clean game back to you within a few minutes or hours. You can change your password before sharing, and after I'm done. That's my usual conditions.

Thanks, I'll pm you. From my experience both engines (WOLF & RPG Maker VXAce) are compatible with text hookers.

I have a pdf download from dlsite.How can I rip file to image?

If it's a PDF file then it's not protected with portal DRM. You may want to search for other threads about ripping images from PDF or google more information about it. In most cases, pdfimages.exe will do all the job properly, but then there are other cases that are not very well described in any specific thread.

Ideally, there should be a set of rules specifically for galleries with digital works, including PDF, detailed instructions of how to properly deal with such files, info about how to ensure that one digital version is better than another one, info about where to buy works and what quality to expect etc. I think this stuff even deserves a separate tag group. But there is no such thing and nobody seems to be interested in this. As a result, there are many galleries with screen-capped, re-encoded, upscaled, oversized images, or even re-constructed (with something like waifu2x) or edited by hand without any notice, also digital content not marked as digital. The community is not in shape for starting to properly deal with improper digital galleries, at least for now. This is one of reasons why I've stopped uploading galleries with digital contents.

dlsite pdf protected,I used a lot sofware for pdf convert to image but it said this file protected and can't rip

Systools PDF Unlocker will remove the protection and then you can use those PDF conversion programs normally.

Yes, you can use various software to remove that protection - PDF permissions locked by owner's password. Another application I can recommend for this is Guaranteed PDF Decrypter (shareware).

I think stuff about pure PDF should be discussed in other threads, as it does not involve any portal-specific DRM.

But i read this thread for the technical knowhow.

Either I forgot how I managed to take screenshots previously, or as someone mentioned a few months ago, they've managed to stop that function too :/

As someone who's just wants to translate untranslated manga/cg's, this is quite annoying (IMG:[invalid] style_emoticons/default/sad.gif)

you can try with some screen capturing software. windows 7 and higher have a basica default one, just in case. it's called SnippingTool.exe and for how basic it is it allows you to set a delay (not a sequence though).

otherwise, you can try with hardware method: press "stamp" button on your keyboard, and paste the result in whatever software that deals with images (anything from Photoshop to Gimp to Paint, from Excel to Word...)


[edit]: this in case the protection didn't disable the function, of course.
