That&#x27;s great. But according to <a href="https:&#x2F;&#x2F;tools.ietf.org&#x2F;html&#x2F;rfc6844" rel="nofollow">https:&#x2F;&#x2F;tools.ietf.org&#x2F;html&#x2F;rfc6844</a>, this is quite recent, and not standardized yet.<p>Do you have any information on which CA&#x27;s already support this, or whether Let&#x27;s Encrypt (intends to) support this?<p>I&#x27;m still hoping for DANE to gain traction, though. Not necessarily as a replacement for CA&#x27;s; there is value in thorough, third-party validation of certificates, but not within the current ecosystem.
