It is a little strange though in how it works. I was restoring a site that had no password set on the backup, but it insisted on me entering one and wouldn't take a blank one. I couldn't recreate the backup with a password because the site was toast. I finally worked around it by setting a password and THEN downloading a copy of import_buddy.php. Then I used the password that I had given import_buddy.php, and it unlocked my backup, even though it wasn't the password on the backup. I'm not sure if this is intentional behavior, but I found it really strange.
