In a fundamental sense, not one of them is "trustworthy". To find out
whether they give you the user-perspective advantage you outline so
concisely above, examine which certificate authorities are listed in Web
browsers commonly used today (and in recent years, to take into account
unmaintained machines with old software).
As to whether the certificate authorities _actually_ give any meaningful
assurance of anything: No, they don't. Bruce Schneier has an entire,
particularly scathing chapter of his book _Secrets and Lies_ where he
explains why they completely fail to deliver on the promise they seem to
And yet: It's a commercial reality that e-commerce sites _must_ pay
Verisign et al their extortionate rates in order to avoid being swamped
by suspicious customer calls about their site not being "secure".

Well, there's mine:
And yes, this _is_ how I do mine.
And before someone suggests it yet again: The biggest reason there
isn't a cheap or free geek collective to run a certificate authority
with the aim of getting it included in common Web browsers is legal
