Subject: VerySign Class 1 Authority - bogus SSL
 certificate?

Hi,

Depending on your trusted-CA package for your SSL client, this
should not verify. There are various ways to confuse SSL clients.
Especially GUI based web-browsers allow to play tricks where
you cant decide whether you are prompted a correct certificate.
Some do not check the signature at all. If in doubt, if there
is any popup on a HTTPS site, theres someone playing games.
I am going to release slides from a speach regarding that topic soon.
