<p class="MsoNormal">This seems reasonable when you are dealing with an online CA. When you are dealing with a root CA, it is currently reasonable to only bring it online once a year to update the CRL, as that is the required frequency. For many offline CAs
it is quite a production to use the HSM, so I think the maximum duration of delegated responder certificates signed by root CAs should be at least a year.<o:p></o:p></p>

<p class="MsoNormal">Regarding delegated OCSP responder certificate validity, if 30 days is a desired goal (or a similar timeframe), I would recommend 45 days to allow the renewal to occur every 30 days, with a 15 day buffer for operational issues. Basically,
for whatever target validity period we should add some buffer time.<o:p></o:p></p>

<p class="MsoNormal">In response to various investigations about OCSP performance, operation, and trying to figure out how we can move to a world of more ubiquitous OCSP stapling, one of the things that comes up is that OCSP responses are very much like the
pre-BR wild-west of certificates.<o:p></o:p></p>

<div>
<p class="MsoNormal">There's also a lot of ways to express these requirements. I considered using a table approach, which I suspect some of our ETSI-audited CA members will be familiar with, and which I find useful, but I thought it best to keep the initial
discussions simple and textual, and then we can make it pretty once we're happy with the substance.<o:p></o:p></p>
