Thanks again Jeremy!<br>
<br>
I would like to state the following fact as food for thought on this
subject....<br>
<br>
Today one can secure a (main) site with an EV certificate and have
all content of that site including frames and iframes secured with a
regular SSL certificate including wild cards. Browsers have always
allowed this with the notable exception of Opera that had at some
point a configuration setting for an "All EV" requirement. So if you
are on an EV site, this doesn't mean that your connection is really
secured with EV - a lot of information can be still leaked to other
parties that have not undergone an extended validation and that's
usually not what you want (but you don't know usually).<br>
<br>
If we consider this fact, I can't see why EV shouldn't be wild card
enabled. Or to take it a step further, why should wild cards be
possible with some weak domain control validation only? It's widely
known that such wild card DVs can be easily abused.<br>
<br>
On the other hand, EV has undergone a serious verification and the
use of an EV certificates for malicious purpose by the certificate
holder is almost zero. Except if it loses the key or something, but
that's an entirely different story.<br>

</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>

</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>
