Subject: [cabfpub] Voting Begins: Ballot FORUM-8: Charter to Establish a
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
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.
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
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

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
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

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.
