Synopsis

Invokes the ReEncrypt operation against AWS Key Management Service.

Syntax

Invoke-KMSReEncrypt
-CiphertextBlob <MemoryStream>
-DestinationEncryptionContext <Hashtable>
-DestinationKeyId <String>
-GrantToken <String[]>
-SourceEncryptionContext <Hashtable>
-Force <SwitchParameter>

Description

Encrypts data on the server side with a new customer master key (CMK) without exposing the plaintext of the data on the client side. The data is first decrypted and then reencrypted. You can also use this operation to change the encryption context of a ciphertext. Unlike other operations, ReEncrypt is authorized twice, once as ReEncryptFrom on the source CMK and once as ReEncryptTo on the destination CMK. We recommend that you include the "kms:ReEncrypt*" permission in your key policies to permit reencryption from or to the CMK. This permission is automatically included in the key policy when you create a CMK through the console, but you must include it manually when you create a CMK programmatically or when you set a key policy with the PutKeyPolicy operation.

Parameters

-CiphertextBlob <MemoryStream>
Ciphertext of the data to reencrypt.
Required?False
Position?Named
Accept pipeline input?False
-DestinationEncryptionContext <Hashtable>
Encryption context to use when the data is reencrypted.
Required?False
Position?Named
Accept pipeline input?False
-DestinationKeyId <String>
A unique identifier for the CMK to use to reencrypt the data. This value can be a globally unique identifier, a fully specified ARN to either an alias or a key, or an alias name prefixed by "alias/".
  • Key ARN Example - arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012
  • Alias ARN Example - arn:aws:kms:us-east-1:123456789012:alias/MyAliasName
  • Globally Unique Key ID Example - 12345678-1234-1234-1234-123456789012
  • Alias Name Example - alias/MyAliasName
Required?False
Position?Named
Accept pipeline input?False
-Force <SwitchParameter>
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?False
-GrantToken <String[]>
A list of grant tokens.For more information, see Grant Tokens in the AWS Key Management Service Developer Guide.
Required?False
Position?Named
Accept pipeline input?False
-SourceEncryptionContext <Hashtable>
Encryption context used to encrypt and decrypt the data specified in the CiphertextBlob parameter.
Required?False
Position?Named
Accept pipeline input?False

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? False
-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? False
-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. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

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? False
-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? False
-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? False
-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
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-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? False

Inputs

This cmdlet does not accept pipeline input.

Outputs

This cmdlet returns a Amazon.KeyManagementService.Model.ReEncryptResponse object containing multiple properties. The object can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
