Remove DRM from PDF ebooks (Adobe Digital Editions)

Remove DRM from PDF ebooks (Adobe Digital Editions)

 

Posting to help anyone out there:

1. First I downloaded/installed python/pycrypto.
   
2. Then I got ineptkey.pyw, ineptepub.pyw(for epub files) ineptpdf.pyw v2 (for pdf files) put all them into my digital editions directory.
   
3. Ran ineptkey.pyw. It found the key and saved as "ADEPTKEY.DER " in the same directory where ineptkey.pyw is.
   
4. Then, I ran ineptpdf.pyw (v2 worked fine). In the dialog window I put the path to the input file(the file was in the my digital edition folder) and named a file name for the outfile file.
   
5. Voila DRM Free!

Thanks REbook for posting information on doing Adobe Digital Editions pdf files. I can now copy move of my reference books to my Kindle DX.

Remove DRM from PDF ebooks

 

.... if I could just remove the DRM from a couple of books I have in PDF format. ;).

Re: Remove DRM from PDF ebooks

 

ineptpdf.pyw can be used for removing DRM from PDF files :)

Re: Remove DRM from PDF ebooks

 

ineptpdf.pyw, version 6.1
aineptpdf.pyw, version 6.3

Re: Remove DRM from PDF ebooks

 

Could anyone, please also provide me with ineptpdf version 4? I tried finding it online but couldn't.

The older Adobe Digital Version is not reading my downloaded books! When I try opening them on it, it stays blank.

Re: Remove DRM from PDF ebooks

 

Why don't you use a newer version instead?

Re: Remove DRM from PDF ebooks

 

With ineptpdf.pyw alone it doesn't work, you need a ".der" file, how do you get that file?

Re: Remove DRM from PDF ebooks

 

ineptkey.pyw (Key-retrieval script) can create a ADEPTKEY.DER:

Re: Remove DRM from PDF ebooks

 

With "ineptkey.pyw" I'm able to create the "adeptkey.der" file. But when I run "ineptpdf.pyw" the "adeptkey.der" file is automatically selected, after that I browse my PDF and I choose the Output file and when I push the Decrypt button it says: "Error: String required: None". What is the problem?

Re: Remove DRM from PDF ebooks

 

This was tested on PDF version 1.4, 1.5, 1.6, 1.7 .

Is your PDF file located in the "My Documents\My Digital Editions\" folder?

Re: Remove DRM from PDF ebooks

 

Yes, it is.

Re: Remove DRM from PDF ebooks

 

What OS do you use? What versions of "ineptkey.pyw", "ineptpdf.pyw", Python and PyCrypto do you have? What is the version of your PDF document?

Re: Remove DRM from PDF ebooks

 

I use Windows 7 64-bit, ineptkey.pyw version 4.4, ineptpdf version 7.2, Python 2.6, PyCrypto 2.1, and I don't know the version of my PDF.

Re: Remove DRM from PDF ebooks

 

Make sure you use pyhton x32 with pycrypto x32. And place ineptpdf and ineptkey into the "My Documents\My Digital Editions\" folder. Also try other versions of ineptpdf and ineptkey.

ineptpdf, version 7.4 (ineptpdf74.pyw)
If it doesn't help, redownload the PDF or reauthorize your ADE and the PDF with your Adobe ID.

Re: Remove DRM from PDF ebooks

 

It worked! I redownloaded the PDF and it worked. Thank you very much for your help.

Re: Remove DRM from PDF ebooks

 

:confused: :(

I use
- Win 7
- Python 2.6.5 32 bit
- ineptkey 4.3
- ineptpdf 7.4
- pycrypto 2.6

Everything seems to work ok except for the following
- the INEPT PDF Decrypter window doesn't close when pressing quit
- the PDF created contains errors

- can't print pages (no pages selected)
- when scrolling through the document at some point I get in Adobe Acrobat error 135 (this repeats itself a couple of times and results in blank pages)
- GSView error

- unknown operator "C"
- file has an unbalanced >> (close dictionary). gsapi_execute_cont returns -8
- File did not complete the page properlly and may be damaged
- warning: file has unbalanced q/Q operators (too many q's)
- gsapi_exit returns 0

Any ideas are welcome.

Re: Remove DRM from PDF ebooks

 

Try older versions of ineptpdf.

Re: Remove DRM from PDF ebooks

 

If I would have a copy of the file and the key I could look into the problem.

Re: Remove DRM from PDF ebooks

 

Where to send the files?

Stefan

Re: Remove DRM from PDF ebooks

 

PM them to inept2

Re: Remove DRM from PDF ebooks

 

I got a problem. I tried use different versions of ineptpdf, but all got the same issue. When choosed the file and the output and pressed "decrypt", the windows appears like this:



Anyone can help? Also when I try open the pdf in adobe digital edition, I got this error msg:

This version of Digital Editions does not support documents protected with Adobe Poli

 

Some PDF files are protected with "Adobe Policy Server" and NOT by "Adobe Digital Editions". ineptpdf doesn't work with such PDF files.

If I'm not mistaken, I used Advanced PDF Password Recovery from Elcomsoft for unlocking such PDF documents and remove editing, printing and copying restrictions from them, but it was long ago. The program allows to open encrypted and password-protected PDF documents.

Re: This version of Digital Editions does not support documents protected with Adobe

 

Thanks, I tried elcomsoft advanced PDF password recovery v5.0 but got this errormessage when try open the pdf:



Any other suggestions? I really need this file, I couldn't rent it for more then 2 days. :(

Re: This version of Digital Editions does not support documents protected with Adobe

 

yabbah, I wish I knew how to help you.

May be you can print it using a virtual PDF printer like DoPDF. I don't really know whether printing is allowed for such files.

Re: Remove DRM from PDF ebooks

 

Get the newest ineptkey from I love cabbages's website.
ineptkey v5 :
Ineptpdf 7.4 is the newest version with ADE support. The 8.4.x version additionally supports FileOpen. For Adobe Lifecycle exists a 'man in the middle' server configuration (simulates and switches ssl values).

ineptpdf8.4.21.pyw
A few rare ADE pdfs can't be decrypted right. The problem is known but there must be a small bug in the dumping methods.

Re: Remove DRM from PDF ebooks

 

I think I've done everything in the posts above, and used so many different versions of inept files I lost track. Anyway, whichever version I use, I get the following message:
Error: could not convert string to float.

( I bought a set of five pdf ebooks, four of them convert no problem, the fifth - the first in the set - gives me that error message).

Can anyone help, please?

Re: Remove DRM from PDF ebooks

 

I follow the instructions to remove the DRM from one of my ebook. and I got the following message :
"error : string required : none"

I don't the finest idea what to do to not have this message.

Thanks for your help.

I have installed : python-2.6, pycrypto py2.6,, ineptkey_v43, ineptpdf.pyw version 6, aineptpdf V6.3, my and I run under Vista

Re: Remove DRM from PDF ebooks

 

Make sure to use Python x32 even if you have Windows Vista x64.
Also try newer versions of ineptkey, ineptpdf.

Re: Remove DRM from PDF ebooks

 

Is there any script that will work on a Mac? Pycrypto is only available for PC.

Re: Remove DRM from PDF ebooks

 

This is not correct. PyCrypto works fine on a Mac. Just download it, unpack. Then open the terminal and navigate to the PyCrypto directory. Then build PyCrypto and install it:

Re: Remove DRM from PDF ebooks

 

If you only use epubs you can use the new ineptkey 5 which doesn't need pycrypto for the Mac. For (ADEPT) pdf decryption pycrypto isn't optional - even for the Mac.

Re: Remove DRM from PDF ebooks

 

Help!!! I am using Adobe Editions version 1.7.2.1131 and i just paid for a great PDF ebook but i try to remove the DRM to put it on my Kindle but it gives me an error (14) when i open the decrypted PDF, so hasn't worked.

I used these two with Python:

ineptkey.pyw version 5
ineptpdf.pyw, version 6.1

also tried same .de key with aineptpdf.pyw, version 6.3

But with no luck :-(

Thanks for reading!

Re: Remove DRM from PDF ebooks

 

Did you create the adeptkey.der key file again (click in the ineptkey.pyw)? Try ineptpdf 8.4.36 or higher.

Re: Remove DRM from PDF ebooks

 

Hi Joblack, no i didn't because i didn't change the version of adeptkey i assumed it would bey the say .der file.

Re: Remove DRM from PDF ebooks

 

Joblack,

I wasn't running PyCrypto so i downloaded this...

PyCrypto 2.1 for 32bit Windows and Python 2.7 (.zip)

And run it on Python 2.7 with Ineptkey 5 and:

Ineptpdf 8.4.34 also retried with 8.4.35 and 8.4.36

and still no luck. This is driving me crazy! lol

Re: Remove DRM from PDF ebooks

 

Some time ago I had a problem reading a PDF in Acrobat Reader. When I opened it up in another PDF-reader (FoxIt) it worked fine.

It seems that the new Acrobat Readers have a lower 'error tollerance'.

Re: Remove DRM from PDF ebooks

 

Are you sure this PyCrypto is for Python 2.7? I haven't seen a PyCrypto for Python 2.7 and one that is for Python 2.6 almost certainly will give problems. If you are not absolutely sure it is for 2.7 then use Python 2.6.

Re: Remove DRM from PDF ebooks

 

Hi, no i'm not sure - i'm in a mess with it all!

I got it from here...
