I have just installed the most recent version of Kali Linux and I am using john the ripper (version 1.9.0-jumbo) to crack passwords in shadow. I have followed the following tutorial cracking linux passwords and get the following output.

kali㉿kali$ sudo unshadow /etc/passwd /etc/shadow > ~/Desktop/passcopy
[sudo] password for kali: 
kali㉿kali$ john --wordlist  /usr/share/wordlists/rockyou.txt ~/Desktop/passcopy 

kali㉿kali$john --show  Desktop/passcopy                                                                         

0 password hashes cracked, 0 left

why no password is shown although I am using 12345 as a password.

This is the passwords in the shadow file in my system:

  • Is there any output when you tried to run john? It's unusual that it would be blank. There is always an indication that it is running.

  • Have you tried re-installing john? What troubleshooting have you done?
