Synopsis

Calls the AWS Key Management Service UpdatePrimaryRegion API operation.

Syntax

Update-KMSPrimaryRegion
-KeyId <String>
-PrimaryRegion <String>
-Select <String>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

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 Using multi-Region keys 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 state: Effect on your KMS key 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.

Parameters

This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-KeyId <String>
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.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the KeyId parameter. The -PassThru parameter is deprecated, use -Select '^KeyId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PrimaryRegion <String>
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.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The cmdlet doesn't have a return value by default. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.KeyManagementService.Model.UpdatePrimaryRegionResponse). Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRegionToCall
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
