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 “Baseline Requirements for the Issuance and
Management of Publicly-Trusted Certificates” as follows, based on Version
1.6.0:

 

Add the following definitions to section 1.6.1:

 

DNS CAA Email Contact: The email address defined in section B.1.2.

 

DNS TXT Record Email Contact: The email address defined in section B.2.2.

 

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 a DNS CAA Email Contact.  The
relevant CAA Resource Record Set MUST be found using the search algorithm
defined in RFC 6844 Section 4, as amended by Errata 5065 (Appendix A).

 

Each email MAY confirm control of multiple FQDNs, provided that each email
address is a DNS CAA Email Contact for each Authorization Domain Name being
validated.  The same email MAY be sent to multiple recipients as long as all
recipients are DNS CAA Email Contacts for each Authorization 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(s) 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 a DNS TXT Record Email Contact for
the Authorization Domain Name selected to validate the FQDN.

 

Each email MAY confirm control of multiple FQDNs, provided that each email
address is DNS TXT Record Email Contact for each Authorization Domain Name
being validated.  The same email MAY be sent to multiple recipients as long
as all recipients are DNS TXT Record Email Contacts for each Authorization
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(s) 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 " <mailto:domainowner at example.com>
domainowner at 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 Record 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.
