Remove DRM from PDF ebooks (Adobe Digital Editions)

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?

Yes, it is.

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?

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.

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.

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

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.

Try older versions of ineptpdf.

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