--
-- 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
-- <https://docs.aws.amazon.com/kms/latest/developerguide/limits.html#aliases-limit KMS aliases quota>.
--
-- __Cross-account use__: No. @ListAliases@ does not return aliases in
-- other Amazon Web Services accounts.
--
-- __Required permissions__:
-- <https://docs.aws.amazon.com/kms/latest/developerguide/kms-api-permissions-reference.html kms:ListAliases>
-- (IAM policy)

-- For details, see
