Self Service : setting and managing password rules for selfservice users ???

Hi,,

1) I'd like to know how and where I could manage password rules apart from setting manually a password in clear the same way that I can do it for CRM regular users.

2) I also want to know if it is possible to have those selfservice users passwords stored encrypted instead of in clear text as it is out of the box (which is competely insane)

Thank you for you advice.
