Developed and delivered a post-quantum TLS KEM enforcement feature for the spiffe/spire repository, enabling administrators to require quantum-resistant key exchange mechanisms for TLS connections. This work introduced a new configuration option, require_pq_kem, which mandates the use of post-quantum-safe KEMs, thereby strengthening the cryptographic security posture of SPIRE deployments. The implementation encompassed Go development, configuration management, and cryptography, with comprehensive updates to documentation and thorough testing to ensure reliability. By focusing on security and administrative control, the contribution addressed emerging cryptographic threats and provided a practical mechanism for enforcing advanced TLS security standards within the SPIRE ecosystem.
