以下是一個更完整的範例。

使用一個依賴來檢查使用者名稱與密碼是否正確。

為此，使用 Python 標準模組 [`secrets`](https://docs.python.org/3/library/secrets.html) 來比對使用者名稱與密碼。

`secrets.compare_digest()` 需要接收 `bytes`，或是只包含 ASCII 字元（英文字符）的 `str`。這表示它無法處理像 `á` 這樣的字元，例如 `Sebastián`。

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"`。

    //   1 byte for the strategy
    //   1 byte for the number of hash functions
    //   4 bytes for the array length
