Can you be more specific what you did (without giving URLs) ...

Can anybody give me websites where I can originally download an e-book that doesn't work with the script (either with they bookkey error or other errors) so I can try it out for myself.

Should be free e-books or at least cheap ones.

i'm having a problem with the decryption. i get the key file fine and i can create the output pdf file but when i try to open this file it says "there was an error opening this document. there is an error reading this document (14)"

i'm running windows 7 64 bit if that helps

Hi mokkie,

no luck at the moment. I've been with this issue since July and I've been waiting for the "working" script...

My aim is to test version 5 of ineptpdf whether works well. I have downloaded a book from ebl database and this book can be deprotected by ineptpdf version 3 successfully. But when I tried to do the same with version 5 of ineptpdf, it failed to work. i.e. after I obtained the adeptkey.der and click ineptpdf_v5.pyw, nothing appears.

As far as I can see the script has two problems. The first is that some features of the pdf file aren't supported. The script works fine but the book isn't openable. The second is the bookkey error.

Can you give the book name (and where you obtained it) which aren't working under v5 but under v3. I'm also interested in a ebook source url (book name + online website) where the book doesn't work with a bookkey error.

Don't use the v5 version yet, it's an early alpha. The v3 (called v4 on the special website) is fine.

So: I need concrete examples (ebook name, where bought, what price), which error? At the moment I'm especially interested in the bookkey error.

Cool - nobody seems to have a problem anymore.

Good to know

Nothing.
I can't decrypt my DRM PDF file.

Then I suggest you give details of what the PDF file is and where it can be obtained. See the post from joblack three messages back.

Yes I still need a source for an e-book where the bookkey error occures. And if possible it should be no reference or special interest ebook for >= 120 USD

Hi joblack
you can trying with this for exemple "Transmissions et réseaux" wich bought in "http://livreelectronique.fnac.com/LIVRES/FICHES/27891.Livre" for 20.20 euro with the error "book key"

thank you

As what you said, it is indeed a alpha version with fatal problems. Now a new 5 version is well done.

PS: usually i obtain ebook from ebl. I do not try amazon, netlib, ellibs etc.

joblack · 12-09-2009, 06:02 AM

I've got an example with the bookkey error - thanks for your support.

Hi joblack,

I was debugging the script, and found that the error was because of the lenght of the book session key in line 1196 (v3 of the script). Maybe there's something wrong in RSA decrypting so that the decryption of the streams does not work.

The RSA decryption is based in the AES key generated by ineptkey script. Maybe is not an AES CBC_MODE key for PDF older versions. i♥cabbages said that uses AES in CBC mode with a random IV... or maybe is not RSA with PKCS#1 v1.5 padding, who knows?

All of these questions influence the dump method, because my "decrypted" PDF has the correct structure.
