Fields
kmsKey

string

Optional. Resource name of the Cloud KMS key that is used to encrypt the object. The Cloud KMS key must be located in the same location as the object. For details, see customer-managed encryption keys.

Format: projects/{projectId}/locations/{location}/keyRings/{keyring}/cryptoKeys/{key}

For example: projects/123456/locations/us-central1/keyRings/my-keyring/cryptoKeys/my-key. The object will be rewritten and set with the specified KMS key.
storageClass

enum (StorageClass)

Optional. Rewrites the object to the specified storage class. Setting this field will perform a full byte copy of the object if the storage class is different from the object's current storage class. If Autoclass is enabled on the bucket, storage class changes are ignored by Cloud Storage.

StorageClass

The Google Cloud Storage class of an object. For more details, see Storage classes. New storage classes can be added in the future.
