I am just trying to understand your asks - Please clarify:

1, My change includes only the public key and not the entire certificate 
information in the measured buffer.

Should I update this current patch set to measure the entire cert. Or, 
can that be done as a separate patch set?

2, Should a regression test be part of this patch set for the key 
measurement changes to be accepted?
