<p class="MsoNormal"><span style="color:#1F497D">Hi Jeremy,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Thanks for bringing this up. Our position is that we would like EV certificates to be better than OV and DV. I think that was what we tried to do when the original specification was created.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">We believe that wildcard certificates have a higher security risk. Another example of a risk is that if a subscriber wants to protect 10 subdomains then a wildcard certificate can be used. But what if an attacker
adds an 11<sup>th</sup> subdomain, then the certificate can still be used. Seems like a risk we can avoid with the current EV spec.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">As such, based on this risk and other examples which have been brought up, we would not be in favor of adding wildcard to EV.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Thanks, Bruce.<o:p></o:p></span></p>

<p class="MsoNormal">During the face-to-face, the forum discussed allowing wildcard characters in EV certificates. The reasons for allowing it were:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">1)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>The lack of wildcard characters is one reason many large enterprises choose OV/DV over EV. As entities move increasingly to cloud-based solutions and as IPv4 addresses become an increasingly limited resource, wildcards are being used
in more and more places. <o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">2)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>EV domain validation is tied to the baseline requirements. The baseline requirements, even with the proposed domain validation revisions, permit validation of the base domain of an FQDN. Validation does not necessarily happen at each
subdomain level. Therefore, putting wildcard characters doesn’t increase the risk as CAs aren’t looking specifically at the FQDN (except as part of the high risk check).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The reasons against allowing it were:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l1 level1 lfo4"><![if !supportLists]><span style="mso-list:Ignore">1)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>CAs are looking at the FQDN as part of the high risk check. (The counter to this was that high risk checks are highly language and CA dependent – I might not catch that bankofamerica.mydomain.com is a high risk domain if I’m operating
outside the US)<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l1 level1 lfo4"><![if !supportLists]><span style="mso-list:Ignore">2)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Eliminating wildcards ensures the requester knows exactly what domains are being covered by the EV cert.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">There were probably more arguments for and against, but I think this gets the discussion started.
