All,

At our IETF 98 session, there was support in the room to adopt draft-rescorla-tls-subcerts [0].  We need to confirm this support on the list so please let the list know whether you support adoption of the draft and are willing to review/comment on the draft before 20170429.  If you object to its adoption, please let us know why.

Clearly, the WG is going to need to work through the trade-offs between short-lived certificates and sub-certs because both seem, to some, to be addressing the same problem.

Cheers,

J&S

I want to see a solution to this problem, but I think we should look at RFC 3820, X.509 Proxy Certificate Profile.  I know that this was implemented, but I do not know if it is still in use.
