<p class="MsoNormal"><span style="color:black">Hi everyone, <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:black">I’d like to resurface the certificate validity period discussion and see if there is a way to move this forward. I’m still keen on seeing a standardized maximum validity period for all certificate types, regardless
of whether the certificate is DV, OV, or EV. I believe the last time this was discussed, we reached an impasse where the browsers favored a shorter validity period for OV/DV and the CAs were generally supportive of a longer-lived EV certificate (39 months).
The argument for a shorter validity period were 1) encourages key replacement, 2) ensures validation occurs more frequently, 3) deters damage caused by key loss or a change in domain control, and 4) permits more rapid changes in industry standards and accelerates
the phase-out of insecure practices. The argument for longer validity periods: 1) customers prefer longer certificate validity periods, and 2) the difficulty in frequent re-validation of information.

<p class="MsoNormal"><span style="color:black">So far, there seems to be two change proposals with a couple of variations:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:black">What are the objections to 1a? With all the automated installers abounding, 1a seems to capture the simplicity and customer convenience of 39 months with the advantages of shorter-lived certs. Who would oppose/endorse
a ballot that does one of these? <o:p></o:p></span></p>
