Hi Ayden,
<div class=""><br class="">
</div>
<div class="">Lets not forget that in terms of protecting user privacy the use of encryption is vital, so I believe this is an important use case. All web server certificates, no matter which flavor of CA is used (from self-signed, to free to high-end) will
result in data encryption at the transport layer. While the encryption is the same (assuming properly configured servers/clients) the difference between TLS certs is the level of authentication of the entity the server represents. </div>
<div class=""><br class="">
</div>
<div class="">Its way out of scope to dive deeper into the various CA business models, but search for Domain Validated, Organizational Validated and Extended Validated for more details on some of the various levels of “authentication”. </div>

<div class="">Thanks for this clarification, Theo. What would be the difference between these basic SSL certificates and those offered freely by, say, Let's Encrypt? (I'm just trying to get a sense of what forms of identity validation are used besides automated
WHOIS/DNS checks here, and to understand whether or not other identity checks might be economical for the Digital Certificate Authority. Thanks.)<br class="">

<p class="">Hi Ayden, <br class="">
</p>
<p class="">These types of SSL certificates are pretty cheap and the verification is pretty simple. Can be through a verification by email or a code in the name servers, as long you can prove control over the domain name.<br class="">
</p>
<p class="">The Extended Validation SSL certificates require way more verification. These are the ones you usually see for web shops and have this "green" bar in the web browser.
<br class="">
</p>
<p class="">Best regards, <br class="">
</p>

<div class="">If I understand this use case correctly, when an SSL certificate is purchased, your system is sending an automated message to the registrant or the technical contact's email address as listed in WHOIS records. If the recipient of this email clicks
a URL, it validates the certificate?<br class="">
</div>
<div class=""><br class="">
</div>
<div class="">If this is the case, I would like to understand how commonplace this practice is. Are these emails only sent once, when the certificate is initially purchased? I cannot imagine a significant volume of these certificates are purchased on a daily
basis, and I struggle to believe that there could be more than, say, 200 such certification bodies globally. If my assumptions are correct, are we talking, here, about a use case applicable to only a handful of businesses worldwide? Businesses selling these
certificates for large volumes of money?<br class="">
</div>
<div class=""><br class="">
</div>
<div class="">The other issue I see is that there is very little verification of information in WHOIS as it stands today. To rely on the email addresses stored in WHOIS to authenticate a certificate strikes me as flawed. Would it not be more appropriate for
the Certification Authority to visit the domain name in question, call the phone number listed on their website, and to clarify with the contact that claims to have purchased your service that they have purchased your service? If the website does not list
even the number for a switchboard, perhaps that should raise red flags?<br class="">
