The AWS::KMS::Alias resource specifies a display name for a KMS key . You can use an alias to identify a KMS key in the AWS KMS console, in the DescribeKey operation, and in cryptographic operations , such as Decrypt and GenerateDataKey .

Adding, deleting, or updating an alias can allow or deny permission to the KMS key. For details, see ABAC for AWS KMS in the AWS Key Management Service Developer Guide .

Using an alias to refer to a KMS key can help you simplify key management. For example, an alias in your code can be associated with different KMS keys in different AWS Regions . For more information, see Using aliases in the AWS Key Management Service Developer Guide .

When specifying an alias, observe the following rules.

  • Each alias is associated with one KMS key, but multiple aliases can be associated with the same KMS key.
  • The alias and its associated KMS key must be in the same AWS account and Region.
  • The alias name must be unique in the AWS account and Region. However, you can create aliases with the same name in different AWS Regions . For example, you can have an alias/projectKey in multiple Regions, each of which is associated with a KMS key in its Region.
  • Each alias name must begin with alias/ followed by a name, such as alias/exampleKey . The alias name can contain only alphanumeric characters, forward slashes (/), underscores (_), and dashes (-). Alias names cannot begin with alias/aws/ . That alias name prefix is reserved for AWS managed keys .

Regions

AWS KMS CloudFormation resources are available in all AWS Regions in which AWS KMS and AWS CloudFormation are supported.

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.kms.*;
 CfnAlias cfnAlias = CfnAlias.Builder.create(this, "MyCfnAlias")
         .aliasName("aliasName")
         .targetKeyId("targetKeyId")
         .build();
