Returns the items you need to import key material into a symmetric encryption KMS key. For more information about importing key material into KMS, see Importing key material in the Key Management Service Developer Guide.
This operation returns a public key and an import token. Use the public key to encrypt the symmetric key material. Store the import token to send with a subsequent ImportKeyMaterial request.
You must specify the key ID of the symmetric encryption KMS key into which you will
import key material. The KMS key
Origin must be
You must also specify the wrapping algorithm and type of wrapping key (public key)
that you will use to encrypt the key material. You cannot perform this operation on
an asymmetric KMS key, an HMAC KMS key, or on any KMS key in a different Amazon Web
To import key material, you must use the public key and import token from the same
response. These items are valid for 24 hours. The expiration date and time appear
GetParametersForImport response. You cannot use an expired token
in an ImportKeyMaterial request. If your key and token expire, send another
The KMS key that you use for this operation must be in a compatible key state. For details, see Key states of KMS keys in the Key Management Service Developer Guide.
Cross-account use: No. You cannot perform this operation on a KMS key in a different Amazon Web Services account.
Required permissions: kms:GetParametersForImport (key policy)
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginGetParametersForImport and EndGetParametersForImport.
public virtual Task<GetParametersForImportResponse> GetParametersForImportAsync( GetParametersForImportRequest request, CancellationToken cancellationToken )
Container for the necessary parameters to execute the GetParametersForImport service method.
A cancellation token that can be used by other objects or threads to receive notice of cancellation.
|DependencyTimeoutException||The system timed out while trying to fulfill the request. You can retry the request.|
|InvalidArnException||The request was rejected because a specified ARN, or an ARN in a key policy, is not valid.|
|KMSInternalException||The request was rejected because an internal exception occurred. The request can be retried.|
|KMSInvalidStateException||The request was rejected because the state of the specified resource is not valid for this request. This exceptions means one of the following: The key state of the KMS key is not compatible with the operation. To find the key state, use the DescribeKey operation. For more information about which key states are compatible with each KMS operation, see Key states of KMS keys in the Key Management Service Developer Guide. For cryptographic operations on KMS keys in custom key stores, this exception represents a general failure with many possible causes. To identify the cause, see the error message that accompanies the exception.|
|NotFoundException||The request was rejected because the specified entity or resource could not be found.|
|UnsupportedOperationException||The request was rejected because a specified parameter is not supported or a specified resource is not valid for this operation.|
