* Opera Software had a root store program until fall 2013. Opera 14+ will use the root store provided by the OS and the list of EV-enabled roots maintained by Google. Opera < 12 use Opera’s online root store, hereafter based on NSS by Mozilla. To get certificates accepted by Opera, apply to the above-mentioned root store programs for the relevant OS. (Based on visit to http://www.opera.com/docs/ca/)

Roots in NSS are listed here – https://www.mozilla.org/en-US/about/governance/policies/security-group/certs/included/ and here: https://docs.google.com/spreadsheet/pub?key=0Ah-tHXMAwqU3dGx0cGFObG9QM192NFM4UWNBMlBaekE&single=true&gid=1&output=html

S/MIME Requirements
v1.0.12 - Ballot SMC014 - Oct 13, 2025

This ballot introduces requirements that a Certificate Issuer MUST deploy DNSSEC validation back to the IANA DNSSEC root trust anchor on all DNS queries associated with CAA record lookups performed by the Primary Network Perspective, effective March 15, 2026. The ballot is intended to maintain consistency in the S/MIME Baseline Requirements with the requirements of Ballot SC-085 which implemented identical requirements in the TLS Baseline Requirements. Note: SC-085 also introduced requirements in TLS Baseline Requirements for the use of DNSSEC in domain control validation. These requirements are automatically adopted in the S/MIME BR by the email domain control methods that include a normative reference to section 3.2.2.4 of the TLS Baseline Requirements. The draft also includes minor corrections to web links in the text. This ballot is proposed by Stephen Davidson (DigiCert) and endorsed by Client Wilson (Apple) and Ashish Dhiman (GlobalSign).
