What protocol exchange is secured by the "certificate" (private/public
key pair, with the public key encased in a CA certificate)? In many case
the protocol already exchanges the "certificate" in binary (DER) form.
It is appropriate to ask what is happening here and why a certificate
needs to be verified "out-of-band" and in what sense it is "verified".

Presumably this is somehow tied to use of the associated private key to
sign some data, but this is far from clear.
