public class CfnAlias
extends CfnResource
implements IInspectable

A CloudFormation `AWS::KMS::Alias`.

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();

Specified by:

inspect in interface IInspectable

Parameters:

inspector - - tree inspector to collect and process attributes. This parameter is required.

getAliasName

public java.lang.String getAliasName()

Specifies the alias name. This value must begin with `alias/` followed by a name, such as `alias/ExampleAlias` .

If you change the value of the AliasName property, the existing alias is deleted and a new alias is created for the specified KMS key. This change can disrupt applications that use the alias. It can also allow or deny access to a KMS key affected by attribute-based access control (ABAC).

The alias must be string of 1-256 characters. It can contain only alphanumeric characters, forward slashes (/), underscores (_), and dashes (-). The alias name cannot begin with alias/aws/ . The alias/aws/ prefix is reserved for AWS managed keys .

Pattern : ^alias/[a-zA-Z0-9/_-]+$

Minimum : 1

Maximum : 256

setAliasName

public void setAliasName(java.lang.String value)

Specifies the alias name. This value must begin with `alias/` followed by a name, such as `alias/ExampleAlias` .

If you change the value of the AliasName property, the existing alias is deleted and a new alias is created for the specified KMS key. This change can disrupt applications that use the alias. It can also allow or deny access to a KMS key affected by attribute-based access control (ABAC).

The alias must be string of 1-256 characters. It can contain only alphanumeric characters, forward slashes (/), underscores (_), and dashes (-). The alias name cannot begin with alias/aws/ . The alias/aws/ prefix is reserved for AWS managed keys .

Pattern : ^alias/[a-zA-Z0-9/_-]+$

Minimum : 1

Maximum : 256

getTargetKeyId

public java.lang.String getTargetKeyId()

Associates the alias with the specified [customer managed key](https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#customer-cmk) . The KMS key must be in the same AWS account and Region.

A valid key ID is required. If you supply a null or empty string value, this operation returns an error.

For help finding the key ID and ARN, see Finding the key ID and ARN in the AWS Key Management Service Developer Guide .

Specify the key ID or the key ARN of the KMS key.

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 KMS key, use ListKeys or DescribeKey .

setTargetKeyId

public void setTargetKeyId(java.lang.String value)

Associates the alias with the specified [customer managed key](https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#customer-cmk) . The KMS key must be in the same AWS account and Region.

A valid key ID is required. If you supply a null or empty string value, this operation returns an error.

For help finding the key ID and ARN, see Finding the key ID and ARN in the AWS Key Management Service Developer Guide .
