Preparing OpenStack for the post-quantum era: A systematic approach to crypto-agility

OpenStack powers clouds used by some of the most security-sensitive organizations on the planet: government agencies, telecommunications providers, financial institutions, and healthcare systems. Behind every API call, every stored secret, and every tenant workload, cryptography quietly holds the trust model together.That trust model is about to face its biggest challenge in decades. Shor’s algorithm, running on a cryptographically relevant quantum computer (CRQC), will break RSA (Rivest-Shamir-Adleman), ECDSA (Elliptic Curve Digital Signature Algorithm), ECDH (Elliptic Curve Diffie-Hellman),
