I have a salt and a password for an application that is using MD5($password + $salt) and I'm looking to crack it. I believe this to be the same format that joomla uses. I'm having trouble figuring out the file format to pass to Jack the Ripper.
I've tried
username:password:salt
username:password$salt
username:password#salt
But I get
./john --format=MD5 --subformat=joomla raw.txt
No password hashes loaded
The password is simple enough that it appears in word lists but I'd like to make a point about brute force times.
