- Seal the KMS such that it cannot be accessed by MinIO server anymore. That will lock **all** SSE-S3 encrypted objects protected by master keys stored on the KMS. All these objects can not be decrypted as long as the KMS is sealed.

* Дуже потужна і проста у використанні система **<abbr title="також відома як: components, resources, providers, services, injectables">Ін'єкція Залежностей</abbr>**.
* Безпека та автентифікація, включаючи підтримку **OAuth2** з **JWT tokens** та **HTTP Basic** автентифікацію.

        // The root artifact may, or may not be resolved so we need to check before we attempt to resolve.
        // This is often an artifact like a POM that is taken from disk and we already have hold of the
        // file reference. But this may be a Maven Plugin that we need to resolve from a remote repository
        // as well as its dependencies.

FastAPI is smart enough (actually, Pydantic is smart enough) to realize that, even though `description`, `tax`, and `tags` have the same values as the defaults, they were set explicitly (instead of taken from the defaults).

So, they will be included in the JSON response.

/// tip

Notice that the default values can be anything, not only `None`.

They can be a list (`[]`), a `float` of `10.5`, etc.

### Bảo mật và xác thực

Bảo mật và xác thực đã tích hợp mà không làm tổn hại tới cơ sở dữ liệu hoặc data models.

Tất cả cơ chế bảo mật định nghĩa trong OpenAPI, bao gồm:

* HTTP Basic.
* **OAuth2** (với **JWT tokens**). Xem hướng dẫn [OAuth2 with JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* API keys in:
    * Headers.
    * Các tham số trong query string.
    * Cookies, etc.

    * Email.
    * UUID.
    * ...及其他.

所有的校验都由完善且强大的 **Pydantic** 处理。

### 安全性及身份验证

集成了安全性和身份认证。杜绝数据库或者数据模型的渗透风险。

OpenAPI 中定义的安全模式，包括：

* HTTP 基本认证。
* **OAuth2** (也使用 **JWT tokens**)。在 [OAuth2 with JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}查看教程。
* API 密钥，在:
    * 请求头。
    * 查询参数。
    * Cookies, 等等。

加上来自 Starlette（包括 **session cookie**）的所有安全特性。
