Adobe ADEPT DRM for PDF circumvented - Page 35

pdurrant · 11-11-2009, 04:53 AM

There is no such software for sale in the US, as it would break US law (DMCA).

The python scripts are the only way to go.

I am a basic computer user and tried to follow the instructions to convert using Python, but I must admit working with the code and getting it to work was beyond me.
Any help is appreciated.

I have the same problem, Plz help us.

In a brain spasm of unbelievable stupidity I purchased an Adept PDF last night, because I was thinking "Adobe Digital Editions" meant ePub as that was what I was going to run immediately afterwards to download the ePub. When I looked at the screen afterwards there was ePub sitting above it as the other format that I should have selected. Doh.

So now I need to trawl through this long thread to find a hint as to where the latest ineptpdf.py might be lurking (v.2 doesn't seem to work). Unless some kind individual can PM me the location?

I have successfully unlocked ePubs so that I can read them in Stanza on my iPhone, so I have the adeptkey.der file. Just need ineptpdf?

Many thanks
Christo the foolish

where can I find ineptpdf v4, thanks

Has anyone seen this error:

DRM'd PDF loads fine in ADE.
ineptpdf v3 runs without complaint
When opening the resulting PDF in Adobe Reader 9.1, I get the error "There was an error opening this document. There was a problem reading this document (131)".

There was a suggestion here to use nitroPDF to open it and resave, but nitroPDF fails to load the file.

If anyone has any ideas, I'd love to hear them. Thanks!

You don't necessarily get an error message when decrypting pdfs that then fail to open (at the time of using ineptpdf) - they just don't.

In Vista at least, when the pdf file is created, if you click on the icon for the file you get a preview of the front page/cover. If it has not decrypted it stays with the standard Adobe/PDF reading program icon instead and cannot do the preview. When you open you get the error, though the file size would indicate that something of note has been created.

Grauheim · 11-25-2009, 09:09 AM

Thanks for replying suecsi. Yes, that is indeed true, I am getting the generic icon, not a preview.

Interestingly the resulting file is readable with foxit reader. But not with Acrobat, and not with Calibre.

But is there any solution?

Some people have reported you decrypt 2 or 3 times to succeed.
Try this and see what happens.

tootees · 11-28-2009, 02:10 PM

Is there something besides Adobe Digital Editions I can use to download DRM'd PDF's from the public library? I was trying to re-install ADE after a major crash and restore and it is coming up with Can't Find Digital Editions Folder. I don't know where the folder could have gone; it was in there when the whole system got zapped! LOL! Apparently I've made a mistake in thinking that the program would re-install without any problems. Silly me. Not only this, but Adobe Reader 7.0 doesn't look the same either, doesn't have the same logo, and didn't open the PDF's either - when everything worked fine before. How could this be? If it's not obvious, I'm at my wit's end! HELP!!!

Sydney's Mom · 11-28-2009, 02:30 PM

Did you make sure the previous edition of ADE was removed from your computer before you reinstalled? Once you reinstall, you will need to activate, with the same email and password you used before. I found I needed to go back to the library and redownload the books I had checked out.

Your Digital Editions folder should be in the path my documents/my digital editions. If it is not, recreate a new folder with that name under my documents and try again. When you download from the library, choose "open" not save. This should open the book in ADE - but you must be patient, it takes a few seconds for the loading process to work after ADE opens. You should see a little box in the middle of the ADE screen, and if you have a failure, it will show you where. A fix that works for me if that happens, is to close ADE and reopen it. You should get an alert that it has not completed prior tasks and ask if you want to continue then. When you click yes, everything seems to get fixed automatically.

cheers

Thank you, thank you, Leep! ADE is back - and all by itself! Like magic. Now if only I could find the Reader I had. That hasn't shown up so I am without a PDF reader for now. Can I still download AR 7.0 or maybe 7.1.0 - or another pdf reader and not have it interfere with ADE?

Thanks again.
Cheers

Hello and congratulations for this fantastic forum!!

It's incredible!! In 2009 and the Adobe's DRM protection seems to be unbreakable!! I can't believe it!! The method of Python 2.6 + Pycrypto + ineptkey v3.pyw... etc is effective in some cases. When the ebook have a DRM protection more sophisticated, this method is useless.
In the next link is the method very well explained, a complete illustrated tutorial and the needed files to download:

http://rapid.org/board/showthread.php?p=1035319

Is incredible that more sophisticated method is an screen capture with Copistar (the only software which is able to capture the screen in Adobe Digital Editions). Unfortunately this software hasn't a crack yet. With demo version the results of screen capture and the final PDF file generated are quite good.

Is there some way to circumvent the DRM protection of complex PDF files?

NOTE: I was making test with method Python 2.6 + Pycrypto + ineptkey v3.pyw... etc and I saw a curious thing.
In first place, if you open several times the .acsm file with ADE, the program generates several encrypted PDF files in the My Digital Editions folder. One encrypted PDF file for each time that the .acsm file has been opened. Note that all the encrypted PDF files generated by ADE are differents but all of them have the same name. Ok.

When you are in the step to decrypt the PDF file with the ineptpub v2.pyw script, if you don't close the window and then decrypt another encrypted PDF file but with another output name, the script generates a EPUB file for the second, third, fourth... What's the reason for this?!
However, if then you try to decrypt the EPUB file with this method for EPUB files, the ineptpub v2.pyw script can't open the file.

joblack · 12-01-2009, 02:21 AM

What do you mean with more complex drm files? The script sometimes doesn#t work when you have some particular pdf 1.5 features included.

That's not the fault of the decryption routine but mostly the 'dump method' which has to be adjusted.

Before you ask, I shortly checked it out but I'm working on my thesis right now and haven't had the time to go deep into it.

Additionally there seem to be a fileopen drm plugin for the Adobe Reader which also hasn't been circumvented. Might be includable in the actual script.

We'll see ...

victor_2203 · 12-01-2009, 08:17 AM

Finally I have got the code to compile the ineptpdf v3 script file. If I use this sript for decrypt a PDF file with DRM protection I get an error during the process: "error decrypting book session key".
However if I use the ineptpdf v2 script I get a PDF file without DRM protection but with all pages blank. Adobe Acrobat Pro 9 can't open it, but if I use the Nitro PDF Pro 6 I can open the PDF file (with blank pages) and I can check that version is a PDF v1.4.

Is there any solution to solve the error message "error decrypting book session key"?
Where I can to get the file or code for ineptpdf v4?
