### Bug or Regression

- Kubeadm: allow the "certs check-expiration" command to not require the existence of the cluster CA key (ca.key file) when checking the expiration of managed certificates in kubeconfig files. ([#106931](https://github.com/kubernetes/kubernetes/pull/106931), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

そのユーザーが存在しない場合は、「Incorrect username or password」というエラーを返します。

エラーには `HTTPException` 例外を使います:

### パスワードのチェック { #check-the-password }

この時点でデータベースからユーザーデータは取得できましたが、まだパスワードを確認していません。

まず、そのデータを Pydantic の `UserInDB` モデルに入れます。

プレーンテキストのパスワードを保存してはいけないので、（疑似の）パスワードハッシュ化システムを使います。

パスワードが一致しなければ、同じエラーを返します。

    // * Everything with (to <= index < from) should be removed.
    // * The element with (index == from) should be kept.
    // * Everything with (index > from) has not been checked yet.

    // Check from the end of the list backwards (minimize expected cost of
    // moving elements when remove() is called). Stop before 'from' because
    // we already know that should be kept.
