Using cracked RC4 key to read a PDF - nullptr - 07-21-2023 I recently wanted crack an old PDF to see what was inside, so I searched around a bit and found out I could crack RC4 encrypted PDFs very quickly. After cracking the key I tried both writing a Python script to decrypt the streams inside the PDF using PyPDF2 and decrypting some streams by hand but PyPDF2 returned an error and my manual tries yielded invalid results. Am I doing something wrong? How would I use this key to decrypt the PDF file? Both an owner and user password is set btw Code: Session..........: hashpdftests RE: Using cracked RC4 key to read a PDF - marc1n - 07-23-2023 https://github.com/openwall/john/blob/bleeding-jumbo/run/pdf2john.pl |
