Does IBM have any feedback for us regarding the test kernel Andy
provided?

We have generated an online signing key to be included in db for OPAL.
In the absence of feedback about whether 4096-bit keys are supported, we
have generated a 2048-bit key.

Our current plan for secure delivery of the public key to IBM is to
deliver the keys in person to George next month.  Does this timeline fit
IBM's needs for receipt of the public keys?  Does it meet your
expectations for a trust path for the keys, or is there another protocol
that should be used?

Can you please clarify if this means you are expecting the db entry to
be delivered as an x509 certificate issued by the CA key listed in KEK,
or if it should be delivered according to the format defined in the UEFI
spec for authenticated variable updates?
