HARICA: Transition Plan for Existing Dual-Purpose Roots

ASSIGNED HARICA
AI Summary

This case tracks HARICA's preliminary transition plan for two 2015 Root CAs, which are currently dual-purpose. HARICA aims to comply with the Mozilla Root Store Policy by transitioning to a single trust bit by December 31, 2028. The proposed plan includes distrust dates for TLS and S/MIME, with complete root removal from NSS scheduled for April 15, 2030. Challenges include legacy compatibility issues and the impact of Chrome's planned clientAuth EKU removal.
