Code Signing Certificate Working Group

I hereby announce that Voting Begins on the following ballot and that
DigiCert affirmatively votes "Yes":



Ballot FORUM-8: Charter to Establish a Code Signing Certificate Working


Purpose of Ballot


It is proposed that the Forum establish a working group to adopt and
maintain a policy, framework, and set of standards related to the issuance
and management of code signing certificates by a third-party Certificate
Issuer, rather than by the platform supplier (i.e. Certificate Consumer)
itself. The work would be based on the Forum's prior adoption of the EV Code
Signing Guidelines, version 1.4, (Ballot 172; 5 July 2016), and additional
work by Forum members who expressly agreed to operate pursuant to the
Forum's IPR Policy, between 2013 and 2015, which resulted in a failed
proposal to adopt a set of baseline requirements for the issuance and
management of code signing certificates
9.pdf; https://cabforum.org/2015/12/17/ballot-158).


It is proposed by Ben Wilson of DigiCert and endorsed by Mike Reilly of
Microsoft and Bruce Morton of Entrust Datacard that the Forum charter a
working group to operate in accordance with the Scope and other provisions
that follow.  This Charter will take effect upon approval of the CAB Forum
by ballot conducted in accordance with Bylaw 5.3. 




Code Signing Certificate Working Group Charter




This introduction provides general information and context with an intent to
assist the interpretation of this Charter.  


A code signing certificate contains the public key corresponding to a
private key that is used by a person or organization to digitally sign
data-such data usually containing instructions (i.e. "code") for hardware to
perform certain tasks. A code signing certificate can be identified by the
existence of an Extended Key Usage (EKU) Object Identifier (OID) of 


The objective of a code signing certificate is to provide a cryptographic
way to identify the source of code. There are a variety of functional models
and use cases whereby a code signing certificate is issued by a Certificate
Issuer to a Subscriber for use in signing code that will run on a particular
computing platform or group of platforms. (Each platform supplier determines
how a chain between a trusted root CA certificate and the code signing
certificate will be created and verified.) 


The primary use case under consideration for the working group is a model
whereby the platform supplier accepts code signing certificates issued by a
third-party Certificate Issuer. A common example of this model is
Microsoft's Authenticode, although others exist.  


Other functional models include those which allow developers to self-sign
code and those in which the platform supplier manages the code signing or
certificate issuance process, and these models are expressly excluded from
the working group's mandate. Common examples of these models that are
expressly excluded from the scope of guidelines to be promulgated by the
working group are Apple's Developer ID program and Google's Android.


Chartering of the Code Signing Certificate Working Group


Upon approval of the CAB Forum by ballot, the Code Signing Certificate
Working Group ("CSCWG") is created to perform the activities as specified in
this Charter, subject to the terms and conditions of the CA/Browser Forum
Bylaws and Intellectual Property Rights (IPR) Policy, as such documents may
change from time to time. In the event of a conflict between this Charter
and any provision in either the Bylaws or the IPR Policy, the provision in
the Bylaws or IPR Policy SHALL take precedence. The definitions found in the
Forum's Bylaws SHALL apply to capitalized terms in this Charter.  


1         Scope


The authorized scope of the CSCWG SHALL be to discuss, adopt, and maintain
policies, frameworks, and sets of standards related to the issuance and
management of code signing certificates by third-party Certificate Issuers
under a publicly trusted root (and not code signing certificates issued
under a private root CA), limited as follows:


a.	EV Code Signing Guidelines, v. 1.4 and subsequent versions
b.	Version 1.0 Draft of November 19, 2015, Baseline Requirements for
the Issuance and Management of Publicly-Trusted Code Signing Certificates
(subject to the CSCWG making a written finding that the provenance of such
document is sufficiently covered by the Forum's IPR Policy) 
c.	Verification requirements for issuance/renewal of code signing
d.	Subscriber protection of private keys, including keys stored in the
e.	Certificate issuance and revocation
f.	Requirements/controls on use of code signing certificates
g.	Mechanisms to engage with AV vendors, researchers, and others
regarding signed malware
h.	Certificate profiles for code signing certificates and Issuing CA
certificates (including the appropriateness of extensions and when those
extensions should be present)
i.	Certificate issuance and revocation
j.	CA operational practices, physical/logical security, etc.


The CSCWG SHALL exercise caution to ensure that its work product does not
impede the issuance of other EKU types.


2         Out of Scope


The CSCWG SHALL NOT develop guidelines, standards, or requirements
applicable to:


a.	Self-signed code;
b.	Platform suppliers / Certificate Consumers; 
c.	Certificates issued under a root certificate that is not publicly
trusted, even though they are managed by Certificate Issuers or other
third-party service providers; or
d.	The code signing or certificate issuance process when managed by a
platform supplier / Certificate Consumer.


3         Charter Expiration


The CSCWG is chartered until it is dissolved as specified in Bylaw 5.3.2(c).


4         Personnel and Participation


4.1         Selection of Officers


Dean Coclin will act as chair of the CSCWG until the first Working Group
Teleconference, at which time the group will select a chair and vice-chair.
The chair and vice-chair will serve until October 31, 2020, or until they
are replaced, resign, or are otherwise disqualified. Thereafter, elections
SHALL be held for chair and vice chair every two (2) years in coordination
with the Forum's election process and in conjunction with its election
cycle. Officer elections SHALL occur in accordance with Bylaw 4.1(c).  


4.2         Eligibility to Participate, Suspension, and Termination of
Membership in CSCWG


4.2.1         Eligibility to Participate

The CSCWG SHALL consist of two classes of voting members, Certificate
Issuers and Certificate Consumers meeting the eligibility criteria below:


(1)      A Certificate Issuer eligible for voting membership in the CSCWG
MUST have a publicly-available audit report or attestation statement in
accordance with one of the following schemes:

*	WebTrust for CAs v.2.0 or newer; or 
*	ETSI EN 319 411-1, which includes normative references to ETSI EN
319 401 (the latest version of the referenced ETSI documents should be
applied); or
*	If a Government Certificate Issuer is required by its Certificate
Policy to use a different internal audit scheme, it MAY use such scheme
provided that the audit either (a) encompasses all requirements of one of
the above schemes or (b) consists of comparable criteria that are available
for public review.


These audit reports must also meet the following requirements:

*	They must report on the operational effectiveness of controls for a
historic period of at least 60 days;
*	No more than 27 months have elapsed since the beginning of the
reported-on period and no more than 15 months since the end of the
reported-on period; and
*	The audit report was prepared by a Qualified Auditor. 


In addition, the Certificate Issuer MUST actively issue code signing
certificates that are accepted for use in computing platforms in which the
platform supplier accepts code signing certificates issued by such
Certificate Issuer. 


(2)    A Certificate Consumer (i.e. a platform supplier) eligible for voting
membership in the CSCWG must produce a computing platform that accepts code
signing certificates issued by third-party Certificate Issuers who meet
criteria set by such Certificate Consumer.


4.2.2         Membership Application/Declaration process


A.	An Applicant not already a member of the Forum SHALL provide the
following information: 


*	Confirmation that the applicant satisfies at least one (1) of the
membership eligibility criteria (and if it satisfies more than one (1),
indication of the single category under which the applicant wishes to
*	The organization name, as they wish it to appear on the Forum Web
site and in official Forum documents.
*	URL of the applicant's main Web site.
*	Names and email addresses of employees who will participate in the
Working Group and Forum as Member representatives.
*	Emergency contact information for security issues related to
certificate trust.


Applicants that qualify as Certificate Issuers or Root Certificate Issuers
must supply the following additional information:


*	URL of the current qualifying audit report.
*	The URL of at least one third party website that includes a
certificate issued by the Applicant in the certificate chain.
*	Links or references to issued end-entity certificates that
demonstrate them being treated as valid by a Certificate Consumer Member.


Such Applicant SHALL become a Member once the CSCWG has determined by
consensus among the Members during a CSCWG Meeting or Teleconference that
the Applicant meets all of the requirements above or, upon the request of
any Member of the CSCWG, by a Ballot among Members of the CSCWG. Acceptance
by consensus shall be determined or a Ballot of the Members shall be held as
soon as the Applicant indicates that it has presented all information
required above and has responded to all follow-up questions from the CSCWG
and the Member has complied with the requirements of Bylaw 5.5.


Certificate Issuer applicants that are not actively issuing code signing
certificates but otherwise meet these membership criteria MAY request to the
CSCWG that they be granted an invitation for Associate Member status in
accordance with Bylaw 3.1, subject to conditions designated by the CSCWG.


The CSCWG SHALL allow participation by Interested Parties, as set forth in
the Bylaws.


B.	Existing CAB Forum Members seeking to participate in the CSCWG, in
accordance to Bylaw 5.3.1(c), MUST formally declare their intent to
participate in writing and provide the CSCWG Chair with this declaration and
evidence that they meet the criteria set forth above. Such Applicants SHALL
become Members of the CSCWG as determined by consensus during a CSCWG
Meeting or Teleconference, or upon the request of any Member of the CSCWG,
by a Ballot among Members of the CSCWG.  


In order to determine the composition of the initial set of CSCWG Members,
at least twenty-four (24) hours prior to the initial meeting of the CSCWG,
the CSCWG Chair SHALL publish a list of Members seeking to participate who
he determines meet the criteria set forth above. As the first order of
business at the first meeting of the CSCWG, those organizations on the
Chair's list of proposed, qualifying Members SHALL vote to determine the
initial set of CSCWG Members.

The Chair of the CSCWG SHALL establish a list for declarations of
participation and manage it in accordance with the Bylaws, the IPR Policy,
and the IPR Policy Agreement.


4.2.3         Ending Working Group Membership

Members may resign from the CSCWG at any time. Resignation or other
termination of membership in the CSCWG does not prevent a Member from
potentially having continuing obligations, under the Forum's IPR Policy or
any other document.


A Certificate Consumer Member's membership will automatically cease if any
of the following become true:

1.        it stops providing updates for its membership-qualifying software
product; and 

2.        six (6) months have elapsed since the last such published update.


A Certificate Issuer's membership in the CSCWG may be suspended if any of
the following become true:

1.        it fails to perform and disclose its membership-qualifying audit
and fifteen (15) months have elapsed since the end of the audit period of
its last successful membership-qualifying audit;

2.        its membership-qualifying audit is revoked, rescinded or

3.        fifteen (15) months have elapsed since the end of the audit period
of its last successful membership-qualifying audit; or

4.        it is no longer the case that its currently-issued certificates
are treated as valid by at least one Certificate Consumer Member of the


Any Member who believes one of the above circumstances is true of any other
Member may report it on the CSCWG's Public Mail List. The CSCWG Chair will
then investigate, including asking the reported Member for an explanation or
appropriate documentation. If evidence of continued qualification for
membership is not forthcoming from the reported Member within five (5)
working days, the CSCWG Chair will announce that such Member is suspended,
such announcement to include the basis upon which the suspension has been


A suspended Member who believes it has then re-met the membership criteria
under the relevant clauses shall post its evidence to the CSCWG Public Mail
List or provide evidence to the CSCWG Chair who SHALL post it to the CSCWG
Public Mail List. The CSCWG Chair will examine the evidence and unsuspend
the member, or not, by announcement to the CSCWG Public Mail List. A
Member's membership will automatically cease six months after it becomes
suspended if the Member has not re-met the membership criteria by that time.


While suspended, a Member may participate in CSCWG Meetings, CSCWG
Teleconferences, and on the CSCWG's discussion lists, but may not propose or
endorse ballots or take part in any form of voting.


Votes cast before the announcement of a Member's suspension will stand.

Group, two-thirds or more of the votes cast by the Certificate Issuers must
be in favor of the ballot and more than 50% of the votes cast by the
Certificate Consumers must be in favor of the ballot. At least one member of
each class must vote in favor of a ballot for it to be adopted. Quorum is
the average number of Member organizations (cumulative, regardless of Class)
that have participated in the previous three (3) Code Signing Certificate
Working Group Meetings or Teleconferences (not counting subcommittee
meetings thereof). For transition purposes, if three (3) meetings have not
yet occurred, quorum is three (3).


5.2         Other Organizational Matters
