Google Cloud announces quantum-safe key import preview
🔒 Google Cloud announced the preview of quantum-safe key import for software-based keys in Cloud KMS, extending its post-quantum offerings including quantum-safe digital signatures and KEMs. The feature uses hybrid public key encryption (HPKE) to wrap keys in a quantum-resistant envelope during transit, mitigating store-now, decrypt-later risks. The import workflow integrates with existing Cloud KMS APIs and supports client-side wrapping via libraries like Tink and OpenSSL, with options for X-Wing, ML-KEM-768, or ML-KEM-1024 and AES-256-GCM for symmetric wrapping.
