為了處理這點，我們會先將 `username` 與 `password` 以 UTF-8 編碼成 `bytes`。

接著我們可以使用 `secrets.compare_digest()` 來確認 `credentials.username` 等於 `"stanleyjobson"`，而 `credentials.password` 等於 `"swordfish"`。

這大致等同於：

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
