*nod*  I agree with this assessment.

Well, no.  You get exactly what was promised: the SSL CA provides a
certificate that assures your users that you followed their criteria and paid
them the money they want.

Your certificate doesn't change after this revelation: it still provides the
same level of encryption, etc, and still provides the same level of assurance
of identity.

Any change there is *entirely* in the realm of perception of security, not
actual security.

I *very* much doubt this will make a significant difference to the perception
of security, except for a few highly skilled and trained technical people.

Heck, many of them probably *already* knew what the value of SSL was to start
with, and didn't assume that your commercial cert was worth anything more than
the paper it was printed on. ;)


Oh, and: http://www.startssl.com/

You can, at least, reduce the burdensome cost of providing an illusion of
security to the non-technical users through these folks and their least-worst
business model for a CA.
