Hi Wayne, As a small clarification - while Chrome has included the certificates, as noted in the readme, the whitelist is based on SPKI. This was intentional, to avoid situations of interoperability issues.
Whitelisting by certificate, rather than either SPKI or SPKI-Tuple, brings with it significant compatibility risks to the ecosystem in terms of being able to respond to issues. We've already seen this born out with respect to DigiCert and their Managed PKI intermediates, and wanted to avoid disruption to both Apple and Google that would otherwise destablize the ecosystem. For example, if you note, there are two Google certificates, but they share the same SPKI and Subject Name - which is why the Chromium whitelist only has one certificate listed, as it extracts the SPKI from that resource as part of the whitelist. Apologies if the README didn't make that clearer, and happy if there are suggestions or corrections based on that :) On Fri, Feb 9, 2018 at 1:55 PM, Wayne Thayer via dev-security-policy < email@example.com> wrote: > On Thu, Feb 8, 2018 at 7:26 AM, Kai Engert via dev-security-policy < > firstname.lastname@example.org> wrote: > > > On 16.10.2017 19:32, Gervase Markham via dev-security-policy wrote: > > > The subCAs that we know of that fall into this category belong to > Google > > > and Apple.
