sure, i was thinking back to previous posts which contemplated all the various possibilities, such as an even shorter word or other fragment being hashed a bazillion times to create the key, which would require conveying the word, how many times to hash it, etc.  even in the case of a standard minikey, you still kind of have to figure out you are dealing with a minikey, which then needs to be hashed to get the actual key.  all of this is kind of moot anyway until you actually figure out some next steps and make some progress on the painting, as it also seems unlikely that the only part of the painting containing relevant information is the ribbons on the key and the flames.  in other words there is still probably plenty to figure out before you need to worry about actually finding the key
