Since its inception, Certificate Transparency (CT) has profoundly transformed the security paradigm of the global WebPKI ecosystem. As a core mechanism for preventing certificate misissuance, detecting anomalous issuance, and strengthening transparent oversight across the CA industry, the CT log network has become an indispensable cornerstone of the modern Internet security ecosystem.
TrustAsia has always been committed to advancing a healthy and trustworthy security ecosystem. Following extensive technical research, engineering validation, and pilot operations, we have accumulated solid experience in operating distributed log clusters and maintaining high-availability governance. Today, TrustAsia is officially opening our public CT log services to the global community. We view the operation of CT logs as a long-term public-good commitment and will continue to provide stable, efficient, and strictly compliant transparency infrastructure for the community.
To facilitate integration and retrieval for monitors, CAs, and security researchers, we have published a complete metadata descriptor file in accordance with community specifications:
The temporal log shards currently open and accepting submissions in our cluster are listed below:
Classic Logs (RFC 6962)
Static Logs (static-ct-api)
Operating public CT logs is a rigorous, ongoing engineering endeavor that requires long-term dedication. We would like to extend our sincere gratitude to the Chromium team, fellow CAs, and all peer teams across the community who have selflessly maintained open log services over the years. It is this spirit of collaboration and openness within the community that has forged the foundation of today's Internet security.
TrustAsia looks forward to working hand in hand with global developers and security organizations to continuously contribute to the openness and transparency of Internet infrastructure!
