Wordpress comment cookies

http://codex.wordpress.org/WordPress_Cookies says that the user password is double-hashed. So when I post a comment and I'm not a user, what is hashed in the cookie?!?!? On that particular blog I came from a link from facebook, if that`s counting.

Edit: 3 cookies

Read the bottom section of that document, the one titled "Commenters." The section you were reading applies only to users who have logged in to Wordpress.

UPDATE: The extra junk after the cookie name is still part of the cookie name, not the value. I believe this is an identifier used to tell different Wordpress installations on the same domain apart, so they won't step on each other's cookies.
