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.
Each CMK can have multiple aliases, but each alias points to only one CMK. The alias name must be unique in the AWS account and region. To simplify code that runs in multiple regions, use the same alias name, but point it to a different CMK in each region.
Because an alias is not a property of a CMK, you can delete and change the aliases of a CMK without affecting the CMK. Also, aliases do not appear in the response from the DescribeKey operation. To get the aliases of all CMKs, use the ListAliases operation.
An alias must start with the word
alias followed by a forward slash (
The alias name can contain only alphanumeric characters, forward slashes (/), underscores
(_), and dashes (-). Alias names cannot begin with
aws; that alias name
prefix is reserved by Amazon Web Services (AWS).
The alias and the CMK it is mapped to must be in the same AWS account and the same region. You cannot perform this operation on an alias in a different AWS account.
To map an existing alias to a different CMK, call UpdateAlias.
For .NET Core and PCL this operation is only available in asynchronous form. Please refer to CreateAliasAsync.
public virtual CreateAliasResponse CreateAlias( String aliasName, String targetKeyId )
String that contains the display name. The name must start with the word "alias" followed by a forward slash (alias/). Aliases that begin with "alias/AWS" are reserved.
Identifies the CMK for which you are creating the alias. This value cannot be an alias. Specify the key ID or the Amazon Resource Name (ARN) of the CMK. For example: Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab To get the key ID and key ARN for a CMK, use ListKeys or DescribeKey.
