Hashcat not cracking PDF hash - DrDinosaur - 04-19-2015
I'm trying to crack a PDF file (version 1.6). Here are the contents of hash.txt: <redacted>
Hashcat says it cracked the hash, but there is no password.

First, do not post hashes here.
Second, the answer to this question is found on our FAQ:

It doesn't seem to show a result. The password is not empty.

The password is already cracked, therefore it's not going to crack it again.
