<p>
The Amazon KMS key identifier for an encrypted DB instance.
</p>
<p>
The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are creating a DB
instance with the same Amazon account that owns the KMS encryption key used to encrypt the new DB instance, then
you can use the KMS key alias instead of the ARN for the KM encryption key.
</p>
<p>
Not applicable. The KMS key identifier is managed by the DB cluster. For more information, see
<a>CreateDBCluster</a>.
</p>
<p>
If the <code>StorageEncrypted</code> parameter is true, and you do not specify a value for the
<code>KmsKeyId</code> parameter, then Amazon Neptune will use your default encryption key. Amazon KMS creates the
default encryption key for your Amazon account. Your Amazon account has a different default encryption key for
each Amazon Region.
