Mozilla's CA Certificate Program
Mozilla’s CA Certificate Program governs inclusion of root certificates in Network Security Services (NSS), a set of open source libraries designed to support cross-platform development of security-enabled client and server applications. The NSS root certificate store is not only used in Mozilla products such as the Firefox browser, but is also used by other companies in a variety of products.
Override Default Root Certificate Settings
Users of Mozilla products may override the default root certificate settings by either deleting the root certificate or by changing the trust bit settings of a root certificate.
- User Root Certificate Settings -- How to override the default root settings in Mozilla products.
Policy and Included CAs
- Mozilla's CA Certificate Policy
- Baseline Requirements -- Mozilla's expectations regarding the CA/Browser Forum's Baseline Requirements.
- NSS:Release_Versions -- Mapping of Root Cert Inclusion Bugs to Mozilla Product Releases
- Pending CAs Spreadsheet -- CAs who have applied for inclusion of their certificates in the Mozilla project Root CA store, and whose applications are pending. Also CAs who have applied to add trust bits or enable EV for certificates that are already included in Mozilla's Root CA store, and their applications are pending.
- Changes to Mozilla's CA Certificate Policy -- How to view changes to the policy, and snapshots of old versions of the policy.
- Updating Mozilla CA Certificate Policy -- How the policy is updated, transitioning to new versions of the policy, things to discuss in regards to updating the Mozilla CA Certificate Policy.
- Dates for Phasing out MD5-based signatures and 1024-bit moduli
Maintenance and Enforcement
- Maintaining Confidence in Root Certificates -- includes potential problems, prevention, and response.
How to Apply for Root Inclusion or Changes
- Process Overview
- How to Apply -- A guide for CAs wishing to include their certificate in Mozilla's Root CA store, and also a guide for CAs wishing to add trust bits or enable EV for a certificate that is already included in Mozilla's Root CA store.
- Root Change Process -- How to request a change to a root certificate that is currently included in NSS. This includes the process for disabling or removing a root certificate from NSS.
- Checklist of CA information required to process a CA's application
- Recommended practices for CAs wishing to have their root CA certificates included in Mozilla products
- Potentially problematic CA practices. This discusses CA practices that are not explicitly forbidden by the Mozilla CA policy, and do not necessarily pose security issues, but that some people have expressed concerns about and that may cause delays in evaluating and approving CA applications. Some of these practices may be addressed in future versions of the Mozilla CA policy.
- Queue for Public Discussion of CA evaluations
- Technical recommendations for root certificates. This is a very first-cut attempt to outline what root certificates should contain, based on the relevant RFCs as supplemented by existing practices.
- Checklist for Subordinate CAs and CSPs Information needed when subordinate CAs are operated by third parties.
- EV Testing in Firefox: Explains how you can test that your CA certificate (that you want to enable for EV) and your OCSP infrastructure is working correctly according to the expectations of Mozilla, Firefox, the NSS library, and conforms to the SSL protocol specifications (as interpreted by Mozilla/NSS software).
- EV certificates and revocation checking. This discusses how revocation checking via OCSP or CRLs affects the UI treatment of EV certificates.
- Certificate download specification. This document describes the data formats used by Mozilla products for installing certificates.
The following Mozilla public forums are relevant to CA evaluation and related issues. Note that each forum can be accessed either as a mailing list or a newsgroup (using an NNTP-newsreader or the Google Groups service).
- Policy forum. This forum is used for discussions of Mozilla policies related to security in general and CAs in particular; among other things, it is the preferred forum for the public comment phase of CA evaluation.
- Crypto forum. This forum is used for discussions of the NSS cryptographic library used in Firefox and other Mozilla-based products, as well as the PSM module that implements higher-level security protocols for Firefox, et.al. Note that this forum was previously used to discuss CA request, but such discussions should now be moved to the policy forum.
- Security forum. This forum is used for discussions of Mozilla security issues in general. Crypto-related discussions should be moved to mozilla.dev.tech.crypto.
