  • •The program is limited to closed testing environments and custom applications.
  • •Certificates from this pilot will not be publicly trusted or used in production.

On October 9, 2026, Microsoft announced the launch of a Post-Quantum Cryptography (PQC) TLS Pilot Program through its Trusted Root Program. This initiative allows approved certificate authorities to test PQC-enabled TLS certificate hierarchies, specifically using ML-DSA-87. The pilot is limited to closed testing environments and is not intended for public trust or production scenarios. Certificates issued under this program will not be publicly trusted or included in the Common CA Database. The focus of the pilot is on interoperability and ecosystem readiness for server authentication. Participants must meet specific requirements to join the program. The pilot program aims to advance cryptographic agility across the ecosystem.
