My b2evolution Version: Not Entered

This is somehow very spooky. I have the b2evolution blog installed at my website. But I forgot the password, its not one of the regular ones I use. Until today I never really used the blog. But now that I want to I can't get in. I never bothered to configure any mail settings. Is there a simple way of changing my password, like in the database? If someone can tell me what encryption it is I could just encrypt a new password for example.

Anyway thanks in advance.
