Any idea about the lenght of those passwords? Less or more than 10-12 characters?
No ideas. I wish I could just sell and cheat - I would come up with ideas. But I personally know only the information indicated in the header. If a password consists of words, then a large length is not a hindrance, if it contains something of the category ^&5GNB67%F5$7896t%edfv9 - then it is long - this is a problem
