The organization targets a staging environment for MTCs by late 2026, with full production deployment expected in 2027. This initiative addresses the need for post-quantum cryptography to extend beyond encryption into authentication at web scale.", "body_md": "Let’s Encrypt plans to pursue a post-quantum-safe Web PKI through Merkle Tree Certificates (MTCs), a new approach that adds post-quantum authentication to the web without sacrificing the speed and reliability that have made TLS universal. The project is targeting late 2026 for a staging environment that issues MTCs, with a production-ready environment planned for 2027. “For much of the last several years, the conversation about post-quantum cryptography has been a conversation about encryption.
