How to crack PDF file passwords using John The Ripper ❓
Real life story
Once a guy gave me an encrypted PDF file and told to crack it. He said it contained an important file and password is
a date of birth he didn't know whose
What stuff I had❓
♦️ Kali Linux(Penetration OS)
♦️ John The Ripper(password cracking tool)
Why John ❓
John is basically one of the best password cracking tools
existing in this world. It can crack almost any encrypted stuffs
How to use ❓
First we're gonna make a hash of the file. My file is in the Desktop
folder.
The hash creator tool's name is
pdf2john.pl
🔅 In Kali, John can be launched from anywhere since it's in Binaries folder.
But hash creator tool is in the John folder
🔅So i needa locate it
root@kali~#: locate pdf2john.pl
And I got the location to be
/usr/share/john/pdf2john.pl
🔅 Next cmds
root@kali~#: cd /usr/share/john
root@kali~#: ./pdf2john.pl /root/Desktop/file.pdf > /root
Desktop/hash.hash
🔅 The first argument contains the location of the file, and the second argument mentions where to store the hash file
✴️ Creating wordlist
That guy told that its a DOB, so I am gonna use crunch to create a wordlist
root@kali~# crunch 8 8 1234567890 -0 /root/Desktop/wordlist.lst
🔅 Length of DOB is 8. So I mentioned 8. In order to get all the guesses, I mentioned
digits from 0 to 9. And file size was 848MB ❗️
✴️ Fire up John The Ripper🔥
🔅 Follow the below commands
root@kali~#: cd Desktop
(Where our hash file is located)
root@kali~#: john --wordlist=wordlist.lst hash.hash
It will take a while but crack the password
ENJOY ❤️
