Your constrain (1) does make the passwords weaker. Why would you want that?
Same for limitation to 20 characters. Why?

So, please, mark all valuable answers as solutions (green button). You can mark more than one answer. I have seen your account. Why do you have so many questions unsolved? CP has rules. One of them is to mark valueable answers as a solution and to vote-up.
