I have a password protected PDF file that I no longer have/remember the password to, and this should be an ideal opportunity to learn another aspect of John. If it matters, I'm using john 1.8.0 Jumbo-1 on Solaris. Reviewing my email archives, plus current documentation, I see at least 3 possible options. Back in August 2012, it looks like we were using npdf2john , but this appears that it is no longer available on github Get npdf2john (from https://github.com/halfgenius/npdf2john) and run it on PDF file(s). -=-=- From the /doc directory in 1.8.0 Jumbo-1, it is suggested to use pdfcrack as a PDF file cracker. -=-=- From the /run directory, It looks like I have pdf2john.py available -=-=- Are there others? Wondering what the current preferred/suggested method of cracking PDF's is? Jerry
