But that means that if you just convert it to a string and return that information directly, you could be leaking a bit of information about your system, that's why here the code extracts and shows each error independently.

## パスワードのハッシュ化と検証

必要なツールを `passlib`からインポートします。

PassLib の「context」を作成します。これは、パスワードのハッシュ化と検証に使用されるものです。

/// tip | 豆知識

PassLibのcontextには、検証だけが許された非推奨の古いハッシュアルゴリズムを含む、様々なハッシュアルゴリズムを使用した検証機能もあります。

例えば、この機能を使用して、別のシステム（Djangoなど）によって生成されたパスワードを読み取って検証し、Bcryptなどの別のアルゴリズムを使用して新しいパスワードをハッシュするといったことができます。
