I'm trying to crack some MD5 hashes given in OWASP's BWA on their DVWA site. I was able to use John the Ripper and the very first time it worked fine and it showed the reversed hashes using the code:
john --format=raw-md5 --wordlist=/usr/share/wordlists/rockyou.txt hash.txt
However, whenever I try to do it again for the exact same file, it gives back the following:
Using default input encoding: UTF-8
Loaded 6 password hashes with no different salts (Raw-MD5 [MD5 128/128 XOP 4x2])
Remaining 1 password hash
Press 'q' or Ctrl-C to abort, almost any other key for status
