Testing Post-Quantum TLS in Python with OpenSSL 3.5

🔐 AWS provides a containerized sample to test post-quantum hybrid TLS (PQ TLS) from Python by bundling OpenSSL 3.5 with a standard interpreter and common libraries. The sample demonstrates hybrid key exchange using ML-KEM alongside classical algorithms and includes examples for boto3/AWS CLI, requests, and low-level ssl sockets. It also shows how to capture traffic and confirm PQ negotiation in TLS handshakes.
