Written by
Updated at November 26, 2024

Schedules the specified key version for destruction.

Scheduled destruction can be cancelled with the SymmetricKeyService.CancelVersionDestruction method.

gRPC request

rpc ScheduleVersionDestruction (ScheduleSymmetricKeyVersionDestructionRequest) returns (operation.Operation)

ScheduleSymmetricKeyVersionDestructionRequest

{
  "key_id": "string",
  "version_id": "string",
  "pending_period": "google.protobuf.Duration"
}

Field

Description

key_id

string

Required field. ID of the key whose version should be scheduled for destruction.

version_id

string

Required field. ID of the version to be destroyed.

pending_period

google.protobuf.Duration

Time interval between the version destruction request and actual destruction.
Default value: 7 days.

  }
  // end of the list of possible fields
}

An Operation resource. For more information, see 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

ScheduleSymmetricKeyVersionDestructionMetadata

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.

error

google.rpc.Status

The error result of the operation in case of failure or cancellation.

Includes only one of the fields error, 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.

response

SymmetricKeyVersion

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.

Includes only one of the fields error, 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.

ScheduleSymmetricKeyVersionDestructionMetadata

Field

Description

key_id

string

ID of the key whose version is being scheduled for destruction.

version_id

string

ID of the version that is being scheduled for destruction.

destroy_at

google.protobuf.Timestamp

Time when the version is scheduled to be destroyed.

SymmetricKeyVersion

Symmetric KMS key version: metadata about actual cryptographic data.

Field

Description

id

string

ID of the key version.

key_id

string

ID of the symmetric KMS key that the version belongs to.

status

enum Status

Status of the key version.

  • STATUS_UNSPECIFIED
  • ACTIVE: The version is active and can be used for encryption and decryption.
  • SCHEDULED_FOR_DESTRUCTION: The version is scheduled for destruction, the time when it will be destroyed
    is specified in the SymmetricKeyVersion.destroy_at field.
  • DESTROYED: The version is destroyed and cannot be recovered.

algorithm

enum SymmetricAlgorithm

Encryption algorithm that should be used when using the key version to encrypt plaintext.

  • SYMMETRIC_ALGORITHM_UNSPECIFIED
  • AES_128: AES algorithm with 128-bit keys.
  • AES_192: AES algorithm with 192-bit keys.
  • AES_256: AES algorithm with 256-bit keys.
  • AES_256_HSM: AES algorithm with 256-bit keys hosted by HSM

created_at

google.protobuf.Timestamp

Time when the key version was created.

primary

bool

Indication of a primary version, that is to be used by default for all cryptographic
operations that don't have a key version explicitly specified.

destroy_at

google.protobuf.Timestamp

Time when the key version is going to be destroyed. Empty unless the status
is SCHEDULED_FOR_DESTRUCTION.

hosted_by_hsm

bool

Indication of the version that is hosted by HSM.
