AWS SDK Version 3 for .NET
API Reference

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.

Container for the parameters to the ListAliases operation. Gets a list of aliases in the caller's Amazon Web Services account and region. For more information about aliases, see CreateAlias.

By default, the ListAliases operation returns all aliases in the account and region. To get only the aliases associated with a particular KMS key, use the KeyId parameter.

The ListAliases response can include aliases that you created and associated with your customer managed keys, and aliases that Amazon Web Services created and associated with Amazon Web Services managed keys in your account. You can recognize Amazon Web Services aliases because their names have the format aws/, such as aws/dynamodb.

The response might also include aliases that have no TargetKeyId field. These are predefined aliases that Amazon Web Services has created but has not yet associated with a KMS key. Aliases that Amazon Web Services creates in your account, including predefined aliases, do not count against your KMS aliases quota.

Cross-account use: No. ListAliases does not return aliases in other Amazon Web Services accounts.

Required permissions: kms:ListAliases (IAM policy)

For details, see Controlling access to aliases in the Key Management Service Developer Guide.

Eventual consistency: The KMS API follows an eventual consistency model. For more information, see KMS eventual consistency.

public class ListAliasesRequest : AmazonKeyManagementServiceRequest

The ListAliasesRequest type exposes the following members


Public Method ListAliasesRequest()


Public Property KeyId System.String

Gets and sets the property KeyId.

Lists only aliases that are associated with the specified KMS key. Enter a KMS key in your Amazon Web Services account.

This parameter is optional. If you omit it, ListAliases returns all aliases in the account and Region.

Specify the key ID or 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.

Public Property Limit System.Int32

Gets and sets the property Limit.

Use this parameter to specify the maximum number of items to return. When this value is present, KMS does not return more than the specified number of items, but it might return fewer.

This value is optional. If you include a value, it must be between 1 and 100, inclusive. If you do not include a value, it defaults to 50.

Public Property Marker System.String

Gets and sets the property Marker.

Use this parameter in a subsequent request after you receive a response with truncated results. Set it to the value of NextMarker from the truncated response you just received.


The following example lists aliases.

To list aliases

var client = new AmazonKeyManagementServiceClient();
var response = client.ListAliases(new ListAliasesRequest 

List<AliasListEntry> aliases = response.Aliases; // A list of aliases, including the key ID of the KMS key that each alias refers to.
bool truncated = response.Truncated; // A boolean that indicates whether there are more items in the list. Returns true when there are more items, or false when there are not.
