# モデル - より詳しく

先ほどの例に続き、複数の関連モデルを持つことが一般的です。

これはユーザーモデルの場合は特にそうです。なぜなら:

* **入力モデル** にはパスワードが必要です。
* **出力モデル**はパスワードをもつべきではありません。
* **データベースモデル**はおそらくハッシュ化されたパスワードが必要になるでしょう。

/// danger | 危険

ユーザーの平文のパスワードは絶対に保存しないでください。常に認証に利用可能な「安全なハッシュ」を保存してください。

知らない方は、[セキュリティの章](security/simple-oauth2.md#password-hashing){.internal-link target=_blank}で「パスワードハッシュ」とは何かを学ぶことができます。

Although this release is labeled _alpha_, the only unstable thing in it is our new APIs. This
release has many critical bug fixes and is safe to run in production. We're eager to stabilize our
new APIs so we can get out of alpha.

 *  New: Support Java 21's virtual threads (‘OpenJDK Project Loom’). We changed OkHttp's internals

field, [`Policies`](/pkg/crypto/x509/#Certificate.Policies), which supports
certificate policy OIDs with components larger than 31 bits. By default this
field is only used during parsing, when it is populated with policy OIDs, but
not used during marshaling. It can be used to marshal these larger OIDs, instead
of the existing PolicyIdentifiers field, by using the
[`x509usepolicies` setting](/pkg/crypto/x509/#CreateCertificate).

Pero si usamos el mismo modelo para otra *path operation*, podríamos estar enviando las contraseñas de nuestros usuarios a cada cliente.
