Comment on Ssl.com: DCV bypass and issue fake certificates for any MX hostnameparent

Comments

It may also be worth mentioning that when using CAA and also using something like LetsEncrypt one can specify which account is permitted to create and update certs and which method is approved DNS in this case. [1]

Example using DNS validation:

    0 iodef "mailto:domainowner@example.net"
    0 issue "letsencrypt.org; validationmethods=dns-01; accounturi=https://acme-v02.api.letsencrypt.org/acme/acct/xxxxxxxxxx"
    0 issuewild "letsencrypt.org; validationmethods=dns-01; accounturi=https://acme-v02.api.letsencrypt.org/acme/acct/xxxxxxxxxx"
Only useful for non-rogue CA's of course and maybe some day crt.sh will be less after-the-fact on all browsers and API clients.
