PicPost can interface with vB; so, does UBBT use "MD5 encruption"?

From PicPost: "vBulletin uses MD5 encryption to encrypt passwords and generate a string of characters to store in the database. When a user logs in, the password they supply is encrypted and compared to the stored encrypted string that corresponds to that username. PhotoPost works with vB's encrypted strings because Perl comes with Digest::MD5, which can duplicate the process."
