Post-Quantum Cryptography: Standards and Progress

Google announces NIST’s finalized post-quantum cryptography standards for key encapsulation and digital signatures, explains the risks of cryptographically relevant quantum computers (e.g., “store now, decrypt later”), advises crypto-agility steps (cryptographic inventory, key rotation, abstraction layers, end-to-end testing), and details its own deployments (e.g., ML-KEM enabled by default in Chrome/QUIC and internal PQC protections) alongside ongoing contributions to ISO/IETF and a commitment to update services across Android, Chrome, and Cloud.
