API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

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 EBS User Guide.


For .NET Core this operation is only available in asynchronous form. Please refer to ModifyEbsDefaultKmsKeyIdAsync.
