Version 1.0.1
Several Web PKI root store operators (“Stores”) have collaborated to create the Common Certificate Authority Database (CCADB), a data repository of certificate and Certificate Authority (CA) information. CAs who wish to be included in participating stores will need to maintain certain information in the CCADB. This document explains what is required of CAs who are required by Store policy to use the CCADB.
Stores may have their own additional CCADB-related requirements. For each root certificate, CAs must comply with the additional requirements pertaining to the Stores which contain that certificate.
This document does not cover how to obtain write access to the CCADB or how to use the CCADB’s web interface. Those topics are outside its scope. CAs should contact an appropriate Store for assistance.
Regardless of more specific provisions in these requirements, CAs have an overarching responsibility to keep the information in the CCADB about themselves, their operations and their certificates accurate, and make updates in a timely fashion.
All data in the CCADB may be made public or semi-public in a variety of forms; CAs should not place any information in the CCADB which they wish to keep confidential. However, Stores are not obliged to publish any CCADB information.
CAs are required to provide the following information for a Primary Point of Contact (POC), and at least one other POC, who may or may not be Primary:
- Name
- Office email address
- Office hours phone number
CAs may optionally designate further POCs, supplying at least one contact method for each. CAs must also supply one or two non-personal contact email aliases which are more likely to continue working as personnel change; these are maintained as part of the CA’s organizational entry.
All Primary POCs should be authorized to speak for and to bind the CA that they represent. At least one of the Primary POCs will hold a CA Community license; other POCs may also apply to a Store to be issued one. Those Primary POCs with a CA Community license are ultimately responsible for keeping CCADB data up-to-date for their CA.
Notification of security and audit-related issues will be emailed to all POCs and the email aliases; CAs are advised to supply sufficient POCs that will enable them to respond to an issue promptly.
If POC or email alias information needs to be updated, the CA should notify one of the Stores containing their root certificates, because this information may only be edited by Stores. See the Store policy documents for Store contact information.
A root certificate is a certificate which is capable of issuing new certificates, which a CA designates as a trust anchor. It will usually be self-signed. CAs are required to maintain correct and current information about their root certificates.
If root certificate information, including audit information, needs to be updated, the CA should notify one of the Stores containing the certificate, because this information may only be edited by Stores. See the Store policy documents for Store contact information.
An intermediate certificate is a certificate capable of issuing new certificates that is not a root certificate. Intermediate certificates that chain up to root certificate(s) in the CCADB and that are not exempt must be entered into the database. This includes certificates that are revoked. For newly-created intermediate certificates, this must happen before the certificate begins issuing publicly-trusted certificates.
Intermediate certificates are exempt from being added to the CCADB if at least one of the following is true:
- The certificate has the Extended Key Usage (EKU) extension and the EKU does not include the anyExtendedKeyUsage or id-kp-serverAuth KeyPurposeIds; or
- The certificate has the Extended Key Usage (EKU) extension and the EKU includes the anyExtendedKeyUsage or id-kp-serverAuth KeyPurposeIds, and the certificate is name constrained as described in section 7.1.5 of the CA/Browser Forum's Baseline Requirements; or
- The root certificate(s) to which the certificate chains up is/are not trusted for server authentication by any Store; or
- The certificate has expired.
When an intermediate certificate chains up to two included root certificates, each instance (i.e. PEM data) of the certificate only needs to be included in the CCADB once.
If a non-exempt intermediate certificate is revoked, the CCADB must be updated to mark it as revoked, giving the reason why, within 24 hours for a security incident, and within 7 days for any other reason.
In the records for both root certificates and intermediate certificates, CAs are required to provide details of the Certificate Policy (CP) and/or Certificate Practice Statement (CPS) documents relating to that certificate, and also statements of attestation of their conformance to various requirements and other operational criteria (“audits”), those statements being made by a competent independent party or parties. These documents are hosted elsewhere and the URLs are stored in the CCADB. The URLs to such CPs, CPSes and audits, and any metadata about them such as the name of the auditor or the date of the audit, need to be updated as new information become available. For technical reasons, URLs to audit statements need to point to a PDF file.
The entry for each intermediate certificate has "Audits Same as Parent" and "CP/CPS Same as Parent" checkboxes. When those are checked, the details do not need to be duplicated from the parent cert. However, the intermediate certificate must be specifically listed in the audit statements of the parent certificate.
URLs for the following documents are required for each certificate:
- Certificate Policy (CP)
- Certificate Practice Statement (CPS)
- Standard audit (WebTrust or ETSI)
- Baseline Requirements (BR) audit (if the certificate is capable of issuing TLS/SSL server certificates)
- Extended Validation (EV) SSL and/or Code Signing audit (if applicable)
CAs must provide English versions of any Certificate Policy, Certification Practice Statement and Audit documents which are not originally in English, with version numbers matching the document they are a translation of. The English version is not required to be authoritative in all cases of dispute, but the CA must attest that the translation is not materially different to the original.
From time to time, a Store may use the CCADB to send information to CAs. Mailshots will be sent to at least the Primary POC and the email aliases, and may also go to one or more of the other POCs; the exact recipient list is defined by the Store sending the information.
