Question

Is there any way to decrypting a pdf protected by an aes-256 bit key?

I have the correct password and I need a command-line tool (or library – perhaps in python 😛 ) for decrypting the file and then doing some operation over it.

The best thing could be if the file could be saved decrypted, then I elaborate it and then I can remove it…

Does anyone know something about it?

Answer 1

import pyPdf                                                                 pdf = pyPdf.PdfFileReader(open('file.pdf')) pdf.decrypt('password') 

You can then do whatever you want with the contents. This will work with either the user or owner passwords.
