Struct aws_sdk_kms::client::fluent_builders::UpdatePrimaryRegion

pub struct UpdatePrimaryRegion { /* private fields */ }

Fluent builder constructing a request to UpdatePrimaryRegion.

Changes the primary key of a multi-Region key.

This operation changes the replica key in the specified Region to a primary key and changes the former primary key to a replica key. For example, suppose you have a primary key in us-east-1 and a replica key in eu-west-2. If you run UpdatePrimaryRegion with a PrimaryRegion value of eu-west-2, the primary key is now the key in eu-west-2, and the key in us-east-1 becomes a replica key. For details, see Updating the primary Region in the Key Management Service Developer Guide.

This operation supports multi-Region keys, an KMS feature that lets you create multiple interoperable KMS keys in different Amazon Web Services Regions. Because these KMS keys have the same key ID, key material, and other metadata, you can use them interchangeably to encrypt data in one Amazon Web Services Region and decrypt it in a different Amazon Web Services Region without re-encrypting the data or making a cross-Region call. For more information about multi-Region keys, see Multi-Region keys in KMS in the Key Management Service Developer Guide.

The primary key of a multi-Region key is the source for properties that are always shared by primary and replica keys, including the key material, key ID, key spec, key usage, key material origin, and automatic key rotation. It's the only key that can be replicated. You cannot delete the primary key until all replica keys are deleted.

The key ID and primary Region that you specify uniquely identify the replica key that will become the primary key. The primary Region must already have a replica key. This operation does not create a KMS key in the specified Region. To find the replica keys, use the DescribeKey operation on the primary key or any replica key. To create a replica key, use the ReplicateKey operation.

You can run this operation while using the affected multi-Region keys in cryptographic operations. This operation should not delay, interrupt, or cause failures in cryptographic operations.

Even after this operation completes, the process of updating the primary Region might still be in progress for a few more seconds. Operations such as DescribeKey might display both the old and new primary keys as replicas. The old and new primary keys have a transient key state of Updating. The original key state is restored when the update is complete. While the key state is Updating, you can use the keys in cryptographic operations, but you cannot replicate the new primary key or perform certain management operations, such as enabling or disabling these keys. For details about the Updating key state, see Key states of KMS keys in the Key Management Service Developer Guide.

This operation does not return any output. To verify that primary key is changed, use the DescribeKey operation.

Cross-account use: No. You cannot use this operation in a different Amazon Web Services account.

Required permissions:

• kms:UpdatePrimaryRegion on the current primary key (in the primary key's Region). Include this permission primary key's key policy.

• kms:UpdatePrimaryRegion on the current replica key (in the replica key's Region). Include this permission in the replica key's key policy.

Implementations

impl UpdatePrimaryRegion

pub async fn send(
    self
) -> Result<UpdatePrimaryRegionOutput, SdkError<UpdatePrimaryRegionError>>

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

pub fn key_id(self, input: impl Into<String>) -> Self

Identifies the current primary key. When the operation completes, this KMS key will be a replica key.

Specify the key ID or key ARN of a multi-Region primary key.

For example:

• Key ID: mrk-1234abcd12ab34cd56ef1234567890ab

• Key ARN: arn:aws:kms:us-east-2:111122223333:key/mrk-1234abcd12ab34cd56ef1234567890ab

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

pub fn set_key_id(self, input: Option<String>) -> Self

Identifies the current primary key. When the operation completes, this KMS key will be a replica key.

Specify the key ID or key ARN of a multi-Region primary key.

For example:

• Key ID: mrk-1234abcd12ab34cd56ef1234567890ab

• Key ARN: arn:aws:kms:us-east-2:111122223333:key/mrk-1234abcd12ab34cd56ef1234567890ab

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

pub fn primary_region(self, input: impl Into<String>) -> Self

The Amazon Web Services Region of the new primary key. Enter the Region ID, such as us-east-1 or ap-southeast-2. There must be an existing replica key in this Region.

When the operation completes, the multi-Region key in this Region will be the primary key.

pub fn set_primary_region(self, input: Option<String>) -> Self

The Amazon Web Services Region of the new primary key. Enter the Region ID, such as us-east-1 or ap-southeast-2. There must be an existing replica key in this Region.

When the operation completes, the multi-Region key in this Region will be the primary key.
