Cloud KMS with Autokey is now in General Availability for Cloud Storage, Compute Engine, BigQuery, Secret Manager, Cloud SQL, and Spanner.

Autokey simplifies creating and using customer-managed encryption keys (CMEKs) by automating provisioning and assignment. With Autokey, key rings, keys, and service accounts don't need to be planned and provisioned before they're needed. Instead, Autokey generates keys on demand as resources are created.

Using keys generated by Autokey can help you consistently align with industry standards and recommended practices for data security, including the HSM protection level, separation of duties, key rotation, location, and key specificity. Keys requested using Autokey function identically to other Cloud HSM keys with the same settings. For more information, see Autokey overview.

June 14, 2024

As previously announced, Cloud KMS has changed the default duration of the scheduled for destruction period from 24 hours to 30 days.

As of February 1, 2024, newly created CryptoKeys use the new default duration of 30 days, unless a different duration is specified during key creation. For more information about key destruction, see Destroy and restore key versions.

Owners of existing CryptoKeys that had used the default duration were given until May 1, 2024 to opt out from automatically updating those keys to use the new default duration. Existing CryptoKeys that were not opted out have been updated to use the new default duration of 30 days. No further action is required from you.

May 16, 2024
