--
-- Returns information about the signing certificates associated with the
-- specified IAM user. If none exists, the operation returns an empty list.
--
-- Although each user is limited to a small number of signing certificates,
-- you can still paginate the results using the @MaxItems@ and @Marker@
-- parameters.
--
-- If the @UserName@ field is not specified, the user name is determined
-- implicitly based on the Amazon Web Services access key ID used to sign
-- the request for this operation. This operation works for access keys
-- under the Amazon Web Services account. Consequently, you can use this
-- operation to manage Amazon Web Services account root user credentials
-- even if the Amazon Web Services account has no associated users.
--
-- This operation returns paginated results.
