POST /#Action=ModifyEbsDefaultKmsKeyId

Changes the default KMS key for EBS encryption by default for your account in this Region.

Amazon Web Services creates a unique Amazon Web Services managed KMS key in each Region for use with encryption by default. If you change the default KMS key to a symmetric customer managed KMS key, it is used instead of the Amazon Web Services managed KMS key. To reset the default KMS key to the Amazon Web Services managed KMS key for EBS, use ResetEbsDefaultKmsKeyId. Amazon EBS does not support asymmetric KMS keys.

If you delete or disable the customer managed KMS key that you specified for use with encryption by default, your instances will fail to launch.

For more information, see Amazon EBS encryption in the Amazon Elastic Compute Cloud User Guide.

Request body fields

Name Type Required Description
KmsKeyId String Yes

The identifier of the Key Management Service (KMS) KMS key to use for Amazon EBS encryption. If this parameter is not specified, your KMS key for Amazon EBS is used. If KmsKeyId is specified, the encrypted state must be true.

You can specify the KMS key using any of the following:

  • Key ID. For example, 1234abcd-12ab-34cd-56ef-1234567890ab.

  • Key alias. For example, alias/ExampleAlias.

  • Key ARN. For example, arn:aws:kms:us-east-1:012345678910:key/1234abcd-12ab-34cd-56ef-1234567890ab.

  • Alias ARN. For example, arn:aws:kms:us-east-1:012345678910:alias/ExampleAlias.

Amazon Web Services authenticates the KMS key asynchronously. Therefore, if you specify an ID, alias, or ARN that is not valid, the action can appear to complete, but eventually fails.

Amazon EBS does not support asymmetric KMS keys.

DryRun Boolean No

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.
