Some small bug fixes.
I am using 8.4.13 on Windows XP SP3 32-bit with Python 2.6.5. When trying to decrypt a PDF encrypted with FileOpen, I get the following error:
The keyfile is 0 byte. Thanks!
What kind of file is it? An ADE ADEPT (e-book) pdf or a FileOpen file. For ADEPT you need the adeptkey.der file but fileopen pdfs don’t need it (you can delete it if not needed for ADEPT files).
The error message isn’t clear to me. Read the FAQS and bug report section for further information.
It is a fileopen PDF, as seen in document properties:
Deleting the blank adeptkey.der file results in the same error.
I’ll have a look at the FAQs and bug report section now.
So looks like my PDF is encrypted, though I am not sure if it is a 40-bit or 128-bit encryption. Is it possible to get the key from where the fileopen plugin has cached the key, given that one can do offline viewing of the file.
I have the algorithm for decrypting the offline information but some times the keys aren’t up to date so it’s easier to get the key from the server. If I should investigate further you might checking the notes concerning sending a pdf file in the bug report section.
