I promise the vote will not actually start at 2:30am Eastern.
However this is probably something I will start a vote on, so please review it closely during the discussion period, instead of waiting until the voting period to read it š -Tim From: Public <public-boun...@cabforum.org> On Behalf Of Tim Hollebeek via Public Sent: Thursday, November 8, 2018 2:31 PM To: CA/B Forum Server Certificate WG Public Discussion List <servercert...@cabforum.org>; CA/Browser Forum Public Discussion List <public@cabforum.org> Subject: [cabfpub] Ballot SC13: CAA Contact Property and Associated E-mail Validation Methods Ballot SC13: CAA Contact Property and Associated E-mail Validation Methods Purpose of Ballot: Increasingly, contact information is not available in WHOIS due to concerns about potential GDPR violations. This ballot specifies a method by which domain holders can publish their contact information via DNS, and how CAs can use that information for validating domain control. The following motion has been proposed by Tim Hollebeek of DigiCert and endorsed by Bruce Morton of Entrust and Doug Beattie of GlobalSign. --- MOTION BEGINS --- This ballot modifies the āBaseline Requirements for the Issuance and Management of Publicly-Trusted Certificatesā as follows, based on Version 1.6.0: Add Section 3.2.2.4.13: Email to DNS CAA Contact Confirming the Applicant's control over the FQDN by sending a Random Value via email and then receiving a confirming response utilizing the Random Value. The Random Value MUST be sent to an email address identified as a CAA contactemail property record as defined in Appendix B. Each email MAY confirm control of multiple FQDNs, provided that the DNS contactemail email address is the same for each Authorized Domain Name being validated. The Random Value SHALL be unique in each email. The email MAY be re-sent in its entirety, including the re-use of the Random Value, provided that its entire contents and recipient SHALL remain unchanged. The Random Value SHALL remain valid for use in a confirming response for no more than 30 days from its creation. The CPS MAY specify a shorter validity period for Random Values. Note: Once the FQDN has been validated using this method, the CA MAY also issue Certificates for other FQDNs that end with all the labels of the validated FQDN. This method is suitable for validating Wildcard Domain Names. Add Section 3.2.2.4.14: Email to DNS TXT Contact Confirming the Applicant's control over the FQDN by sending a Random Value via email and then receiving a confirming response utilizing the Random Value. The Random Value MUST be sent to an email address identified as a DNS TXT record email contact. See Appendix B for the for the format of the DNS TXT record email contact. Each email MAY confirm control of multiple FQDNs, provided that the DNS contactemail email address is the same for each Authorized Domain Name being validated. The Random Value SHALL be unique in each email. The email MAY be re-sent in its entirety, including the re-use of the Random Value, provided that its entire contents and recipient SHALL remain unchanged. The Random Value SHALL remain valid for use in a confirming response for no more than 30 days from its creation. The CPS MAY specify a shorter validity period for Random Values. Note: Once the FQDN has been validated using this method, the CA MAY also issue Certificates for other FQDNs that end with all the labels of the validated FQDN. This method is suitable for validating Wildcard Domain Names. Add Appendix B: DNS Contact Properties These methods allow domain owners to publish contact information in DNS for the purpose of validating domain control. B.1. CAA Methods B.1.1. CAA contactemail Property SYNTAX: contactemail <rfc6532emailaddress> The CAA contactemail property takes an email address as its parameter. The entire parameter value MUST be a valid email address as defined in RFC 6532 section 3.2, with no additional padding or structure, or it cannot be used. The following is an example where the holder of the domain specified the contact property using an email address. $ORIGIN example.com . CAA 0 contactemail "domainow...@example.com <mailto:domainow...@example.com> " The contactemail property MAY be critical, if the domain owner does not want CAs who do not understand it to issue certificates for the domain. B.2. DNS TXT Methods B.2.1. DNS TXT Email Contact The DNS TXT record MUST be placed on the "_validation-contactemail" subdomain of the domain being validated. The entire RDATA value of this TXT record MUST be a valid email address as defined in RFC 6532 section 3.2, with no additional padding or structure, or it cannot be used. --- MOTION ENDS --- *** WARNING ***: USE AT YOUR OWN RISK.
