Is Docker Quantum Safe?
No. Docker image signing uses classical cryptography (RSA/ECDSA), and container-to-registry TLS depends on the host TLS stack.
Key Takeaway: Docker is NOT quantum safe. Scan container images for quantum-vulnerable cryptographic libraries. Generate CBOM for all container images with QScout.

Technical Analysis
Docker is NOT quantum safe. Docker Content Trust uses Notary for image signing with RSA or ECDSA keys. Docker registry communication uses TLS with classical key exchange. Container images may embed applications with quantum-vulnerable cryptographic libraries. A comprehensive quantum security assessment for Docker environments requires scanning both the orchestration layer and application code within containers.
