Ballot 201 - .Onion Revisions 

This ballot is meant to cure any potential problems with Ballot 198, which
may have been invalid due to ambiguities in what was presented to the Forum
for vote. This Ballot 201 attempts to clarify Appendix F of the EV
Guidelines concerning the Tor Service Descriptor Hash extension and that
inclusion of the extension in the TBSCertificate is required. 

The following motion has been proposed by Jeremy Rowley of DigiCert and
endorsed by Ryan Sleevi of Google and Wayne Thayer of GoDaddy to introduce
new Final Maintenance Guidelines for the "Guidelines for the Issuance and
Management of Extended Validation Certificates" (EV Guidelines). 

Attached is a PDF with a redline showing how Appendix F of the current EV
Guidelines will be amended.


Part 1: 

The CA/Browser Forum, recognizing that Ballot 198 did not include a redline
version against the current Final Maintenance Guidelines, thereby
constitutes an invalid Ballot. As a consequence, the Forum agrees that the
changes shall not be made to the appropriate Final Maintenance Guideline,
and as such, no IPR Review Notice is in force for Ballot 198: 

Part 2: 

Revise Appendix F, Section 1, to read as follows: 

Appendix F - Issuance of Certificates for .onion Domain Names 

A CA may issue an EV Certificate with .onion in the right-most label of the
Domain Name provided that issuance complies with the requirements set forth
in this Appendix: 

1. CAB Forum Tor Service Descriptor Hash extension ( 

The CA MUST include the CAB Forum Tor Service Descriptor Hash in the
TBSCertificate to convey hashes of keys related to .onion addresses. The CA
MUST include the Tor Service Descriptor Hash extension using the following

cabf-TorServiceDescriptorHash OBJECT IDENTIFIER ::= { } 

SEQUENCE ( 1..MAX ) of TorServiceDescriptorHash 

TorServiceDescriptorHash:: = SEQUENCE { 

onionURI UTF8String 

algorithm AlgorithmIdentifier 

subjectPublicKeyHash BIT STRING 


Where the AlgorithmIdentifier is a hashing algorithm (defined in RFC 6234)
performed over the DER-encoding of an ASN.1 SubjectPublicKey of the .onion
service and SubjectPublicKeyHash is the hash output. 

--Motion Ends-- 

The procedure for approval of this Final Maintenance Guideline ballot is as
follows (exact start and end times may be adjusted to comply with applicable
Bylaws and IPR Agreement): 

BALLOT 201 Status: Final Maintenance Guideline            Start time (22:00
UTC)   End time (22:00 UTC) 

Discussion (7 to 14 days)
May 25, 2017                    June 1, 2017 

Vote for approval (7 days)
June 1, 2017                      June 8, 2017 

If a vote of the Forum approves this ballot, the Chair will initiate a
30-day IPR Review Period by sending out an IPR Review Notice. 

After 30 days of announcing the IPR Review period by the Chair:

a.	If Exclusion Notice(s) are filed, this ballot approval is rescinded
and a PAG will be created; or 
b.	If no Exclusion Notices are filed, this ballot becomes effective at
end of the IPR Review Period. 

>From Bylaw 2.3: If the Draft Guideline Ballot is proposing a Final
Maintenance Guideline, such ballot will include a redline or comparison
showing the set of changes from the Final Guideline section(s) intended to
become a Final Maintenance Guideline, and need not include a copy of the
full set of guidelines. Such redline or comparison shall be made against the
Final Guideline section(s) as they exist at the time a ballot is proposed,
and need not take into consideration other ballots that may be proposed
subsequently, except as provided in Bylaw Section 2.3(j). 

Votes must be cast by posting an on-list reply to this thread on the Public
list. A vote in favor of the motion must indicate a clear 'yes' in the
response. A vote against must indicate a clear 'no' in the response. A vote
to abstain must indicate a clear 'abstain' in the response. Unclear
responses will not be counted. The latest vote received from any
representative of a voting member before the close of the voting period will
be counted. Voting members are listed here: https://cabforum.org/members/ 

In order for the motion to be adopted, two thirds or more of the votes cast
by members in the CA category and greater than 50% of the votes cast by
members in the browser category must be in favor. Quorum is half of the
number of currently active Members, which is the average number of Member
organizations that have participated in the previous three Forum-wide
meetings (both teleconferences and face-to-face meetings).  Under Bylaw
2.2(g), at least the required quorum number must participate in the ballot
for the ballot to be valid, either by voting in favor, voting against, or
