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.

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.

Get the newest ineptkey from I love cabbages's website.
ineptkey v5 :

http://pastie.org/1030386

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.

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?

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

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