// we could just insert before selecting and catch the error,
      // but my hunch is that it's cheaper not to serialize the blob
      // from JS to C if we don't have to (TODO: confirm this)

      ' (digest, body, escaped) VALUES (?,?,1)';
      tx.executeSql(sql, [digest, escapeBlob(data)], function () {
