Subject: current suggested/supported method for extracting hash from PDF files?

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
