 ** KmsKeyArn **   <a name="ManagedBlockchain-Type-MemberConfiguration-KmsKeyArn"></a>
The Amazon Resource Name (ARN) of the customer managed key in AWS Key Management Service (AWS KMS) to use for encryption at rest in the member. This parameter is inherited by any nodes that this member creates. For more information, see [Encryption at Rest](https://docs.aws.amazon.com/managed-blockchain/latest/hyperledger-fabric-dev/managed-blockchain-encryption-at-rest.html) in the *Amazon Managed Blockchain Hyperledger Fabric Developer Guide*.  
Use one of the following options to specify this parameter:  
+  **Undefined or empty string** - By default, use an AWS KMS key that is owned and managed by AWS on your behalf.
+  **A valid symmetric customer managed KMS key** - Use the specified KMS key in your account that you create, own, and manage.

  Amazon Managed Blockchain doesn't support asymmetric keys. For more information, see [Using symmetric and asymmetric keys](https://docs.aws.amazon.com/kms/latest/developerguide/symmetric-asymmetric.html) in the * AWS Key Management Service Developer Guide*.

  The following is an example of a KMS key ARN: `arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab`
