created_by	string ID of the user or service account who initiated the operation.
modified_at	google.protobuf.Timestamp The time when the Operation resource was last modified.
done	bool If the value is false, it means the operation is still in progress. If true, the operation is completed, and either error or response is available.
metadata	google.protobuf.Any<RotateSymmetricKeyMetadata> Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
result	oneof: error or response The operation result. If done == false and there was no failure detected, neither error nor response is set. If done == false and there was a failure detected, error is set. If done == true, exactly one of error or response is set.
error	google.rpc.Status The error result of the operation in case of failure or cancellation.
response	google.protobuf.Any<SymmetricKey> if operation finished successfully.

RotateSymmetricKeyMetadata

Field	Description
key_id	string ID of the key being rotated.
new_primary_version_id	string ID of the version generated as a result of key rotation.

SymmetricKey

Field	Description
id	string ID of the key.
folder_id	string ID of the folder that the key belongs to.
created_at	google.protobuf.Timestamp Time when the key was created.
name	string Name of the key.
description	string Description of the key.
labels	map<string,string> Custom labels for the key as key:value pairs. Maximum 64 per key.
status	enum Status Current status of the key. CREATING: The key is being created. ACTIVE: The key is active and can be used for encryption and decryption. Can be set to INACTIVE using the SymmetricKeyService.Update method. INACTIVE: The key is inactive and unusable. Can be set to ACTIVE using the SymmetricKeyService.Update method.
primary_version	SymmetricKeyVersion Primary version of the key, used as the default for all encrypt/decrypt operations, when no version ID is specified.
default_algorithm	enum SymmetricAlgorithm Default encryption algorithm to be used with new versions of the key. AES_128: AES algorithm with 128-bit keys. AES_192: AES algorithm with 192-bit keys. AES_256: AES algorithm with 256-bit keys.
rotated_at	google.protobuf.Timestamp Time of the last key rotation (time when the last version was created). Empty if the key does not have versions yet.
rotation_period	google.protobuf.Duration Time period between automatic key rotations.

ListOperations

Lists operations for the specified symmetric KMS key.

rpc ListOperations (ListSymmetricKeyOperationsRequest) returns (ListSymmetricKeyOperationsResponse)

ListSymmetricKeyOperationsRequest

Field	Description
key_id	string Required. ID of the symmetric KMS key to get operations for. To get the key ID, use a SymmetricKeyService.List request. The maximum string length in characters is 50.
page_size	int64 The maximum number of results per page that should be returned. If the number of available results is larger than page_size, the service returns a ListSymmetricKeyOperationsResponse.next_page_token that can be used to get the next page of results in subsequent list requests. Default value: 100. The maximum value is 1000.
page_token	string Page token. To get the next page of results, set page_token to the ListSymmetricKeyOperationsResponse.next_page_token returned by a previous list request. The maximum string length in characters is 100.

ListSymmetricKeyOperationsResponse

Field	Description
operations[]	operation.Operation List of operations for the specified key.
next_page_token	string This token allows you to get the next page of results for list requests. If the number of results is larger than ListSymmetricKeyOperationsRequest.page_size, use the next_page_token as the value for the ListSymmetricKeyOperationsRequest.page_token query parameter in the next list request. Each subsequent list request will have its own next_page_token to continue paging through the results.

Operation

Field	Description
id	string ID of the operation.
description	string Description of the operation. 0-256 characters long.
created_at	google.protobuf.Timestamp Creation timestamp.
created_by	string ID of the user or service account who initiated the operation.
modified_at	google.protobuf.Timestamp The time when the Operation resource was last modified.
done	bool If the value is false, it means the operation is still in progress. If true, the operation is completed, and either error or response is available.
metadata	google.protobuf.Any Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
result	oneof: error or response The operation result. If done == false and there was no failure detected, neither error nor response is set. If done == false and there was a failure detected, error is set. If done == true, exactly one of error or response is set.
error	google.rpc.Status The error result of the operation in case of failure or cancellation.
response	google.protobuf.Any The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is the standard Create/Update, the response should be the target resource of the operation. Any method that returns a long-running operation should document the response type, if any.
