[cabfpub] Ballot 199 - Require commonName in Root and Intermediate Certificates

Mon May 8 09:37:45 UTC 2017

Hi

Buypass votes NO.

I apologize for not commenting on this ballot earlier.

I support that CN is required in all certificates, but I don’t support that we should require a unique CN across all CA certificates issued by the issuing CA.

As long as we issue a new certificate for the same CA entity (i.e. with the same CA key and same validity), it is not obvious that we should have to “change the name” of this entity. CN is a part of the Subject field and thus a part of the name of the CA.

Before we introduce such a requirement, I think that we need to better understand the consequences for all actors, including the CAs, the Browsers and server applications handling installed certificates at customer sites.

Regards
Mads

Subject: [cabfpub] Ballot 199 - Require commonName in Root and Intermediate Certificates

This is the corrected text (one word change) of ballot 199 which is currently in the voting period (voting ends on 9th May).

Ballot 199 - Require commonName in Root and Intermediate Certificates
Purpose of Ballot: Section 7.1.4.3 of the BRs, which deals with Subject Information for Subordinate CA Certificates, currently requires only that all information in a Subordinate CA Certificate is accurate; it does not say what information is required. Some of the necessary information is required elsewhere in the BRs, but it is not complete - commonName is missing. If commonName is omitted, DN clashes can more easily occur. So this motion centralises that information in the obvious place, and adds a commonName requirement.
The following motion has been proposed by Gervase Markham of Mozilla and endorsed by Patrick Tronnier of OATI and Ryan Sleevi of Google:

-- MOTION BEGINS --

Make the following changes to the Baseline Requirements:

* Delete 7.1.2.1 (e), which currently defines the Subject Information required in a Root CA Certificate.

* Delete 7.1.2.2 (h), which currently defines the Subject Information required in a Subordinate CA Certificate.

* Rename section 7.1.4.2, currently titled "Subject Information", to "Subject Information - Subscriber Certificates".

* Rename section 7.1.4.3, currently titled "Subject Information - Subordinate CA Certificates" to "Subject Information - Root Certificates and Subordinate CA Certificates".

* Based on the style used in 7.1.4.2.2 and the content from the now-deleted 7.1.2.1 (e) and 7.1.2.2 (h), add the following section 7.1.4.3.1:

7.1.4.3.1 Subject Distinguished Name Fields

Certificate Field: subject:commonName (OID 2.5.4.3)

Required/Optional: Required

Contents: This field MUST be present and the contents SHOULD be an identifier

for the certificate such that the certificate's Name is unique across all

certificates issued by the issuing certificate.

b. Certificate Field: subject:organizationName (OID 2.5.4.10)

Required/Optional: Required

Contents: This field MUST be present and the contents MUST contain

either the Subject CA’s name or DBA as verified under Section 3.2.2.2.

The CA may include information in this field that differs slightly from

the verified name, such as common variations or abbreviations,  provided

that the CA documents the difference and any abbreviations used are

locally accepted abbreviations; e.g., if the official record shows

“Company Name Incorporated”, the CA MAY use “Company Name Inc.” or

“Company Name”.

c. Certificate Field: subject:countryName (OID: 2.5.4.6)

Required/Optional: Required

Contents: This field MUST contain the two‐letter ISO 3166‐1 country code

for the country in which the CA’s place of business is located.
