KMS / Client / list_aliases



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/<service-name>, 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.

Request Syntax

response = client.list_aliases(
  • KeyId (string) –

    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.

  • Limit (integer) –

    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.

  • Marker (string) – 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.

Response Structure

  • (dict) –

    • Aliases (list) –

      A list of aliases.

      • (dict) –

        Contains information about an alias.

        • AliasName (string) –

          String that contains the alias. This value begins with alias/.

        • AliasArn (string) –

          String that contains the key ARN.

        • TargetKeyId (string) –

          String that contains the key identifier of the KMS key associated with the alias.

        • CreationDate (datetime) –

          Date and time that the alias was most recently created in the account and Region. Formatted as Unix time.

        • LastUpdatedDate (datetime) –

          Date and time that the alias was most recently associated with a KMS key in the account and Region. Formatted as Unix time.

    • NextMarker (string) –

      When Truncated is true, this element is present and contains the value to use for the Marker parameter in a subsequent request.

    • Truncated (boolean) –

      A flag that indicates whether there are more items in the list. When this value is true, the list in this response is truncated. To get more items, pass the value of the NextMarker element in thisresponse to the Marker parameter in a subsequent request.
