Yes it is completely useless against random strings as one would expect, but with word salad it not completely useless. For example, it can find words like &quot;tequieromuchogerald&quot; and &quot;paulaalejandrailove&quot; easily enough. I haven&#x27;t fully explored its ability to do this, but I suspect starting with a dictionary of words instead of a random population might aid it in finding XKCD like random passwords. In general I don&#x27;t disagree though, passphrases if chosen correctly can be completely intractable to a password cracker.
