You go to a Web page that has the HTML or Javascript control for generating
a keypair. But the keypair is generated on the end user's computer.

The service could send you an ActiveX keygen control with a backdoor but I
am not on Windows right now. I generated the keypair on Chrome and I have
all runtime objects turned off.

The CA returns the signed certificate to you, but that is the public key
part.
