Hi Joshua Thanks for the explanation . I now understand how it is salted :). I do have a few queries though . On passing the sting "echo -n "string" | grub-md5-crypt 2> /dev/null | grep -v Password" , the prompt is for Retype password and then passwords don't match . What is going wrong here ? Could you guide me please ?
