I have this PHP code with me :
$auth = md5($username.$password.$salt);
I have a dummy value :
$username = user
$password = password
And I also have the resulting MD5 Hash : b4fbb742bc2a24bc033dbfb4f4582e08
I need to find the salt which has been used. Is this possible in something like John The Ripper or Hashcat etc?
