Thank you! Finally I'll be able to *buy* and read some stuff that was unusable for me before.

Used ineptpdf8.4.48 for PDF-file with Adobe LiveCycle Policy (Adobe.APS[adbe.pdrl.v0]) 128-bit security v.4 protection without password or key file input. Got the error: Cannot find principal key for this pdf. Does anyone know the solution?

You need a principalkey for every publisher (which you can sniff out of the network connection). Check out the information in the comments on my blog.

Sniffer?
Quote:
As I am not a person with a medium (or a low) know-how with regards to Apache, I am stuck without a principal key. However, what I can do is to run a sniffer such a WireShark. Using this method, would I be able to pick-up the PrincipalKey from the logs? Or will the key be encrypted itself? I am asking since I have dawsonera books but no key … ;-/ Thank you kindly. |

Yesterday I've successfully decrypted several PDFs encrypted with Policy Server.
I obtained the PDFs from our online library. First ineptkey couldn't find the key, but after installing ADE ineptkey automatically found one although ADE couldn't load the PDFs. Today I wanted to decrypt other PDFs from the same online library, but it doesn't work anymore. I get the message "Offlinekey cannot be decrypted". I'll try to sniff the PrincipalKey with Wireshark. Maybe I can find it. Thanks for your scripts! They worked great yesterday for me! |

Anyway I suspect they haven't changed the PrincipalKey, just increased the MinorKeyRevision so that the PrincipalKey has to be transformed with the MKRevision (in a not yet known way). |

I was afraid it won't work.
Tried it anyway. Unsuccessful as you said ;-) Maybe I'll try to setup an apache server. Thank you! |

The new version is working again!
Thank you! PDF XChange Viewer is complaining though that the document is broken: ![]() Didn't find any problems yet. Just resaved the document and the document is fine. |

This is a well known pdf parser problem. No immediate solution is available and as Tetrachroma (and others) explained a pdf format expert is probably needed to solve the problem.

Hey, I’m having trouble. I have the 8.4.48, but I keep getting the "Pywin extention (win32API module) needed" error. I’ve already downloaded the Pywin32-214 stuff, but I’m not sure how to install it. I click on the setup icon in the Pywin 32-214 subfolders and something pops up like MSDOS but then disappears real quick. I’m sort of a rookie and hoping someone can guide me in the right direction. How do you install the Win32 stuff?
procedures i did = Phyton 2.7 installed > Pycrypto 2.1.win32-py2.7 installed > Pywin32-214 downloaded and extracted. I hope you could help me on this thank you in advance! |

Hello. I am using 8.4.51 to try to remove DRM from a FileOpen pdf. I am simply getting:
Error: 'Error' Enabling debug, in the debug file I see what looks like a bunch of variables and their values. Then a long settings url. Then Settings and Retval=answer. Then a 1st url and then a 1st preresult. I don't know if there is supposed to be more info or not. Anything I can do to troubleshoot some more? |
