모든 검증은 잘 확립되어 있고 견고한 **Pydantic**이 처리합니다.

### 보안과 인증 { #security-and-authentication }

보안과 인증이 통합되어 있습니다. 데이터베이스나 데이터 모델과 타협하지 않습니다.

다음을 포함해 OpenAPI에 정의된 모든 보안 스키마:

* HTTP Basic.
* **OAuth2**(**JWT tokens** 또한 포함). [JWT를 사용한 OAuth2](tutorial/security/oauth2-jwt.md) 자습서를 확인해 보세요.
* 다음에 들어 있는 API 키:
    * 헤더.
    * 쿼리 매개변수.
    * 쿠키 등.

추가로 Starlette의 모든 보안 기능(**세션 쿠키** 포함)도 제공합니다.

        try (RdmaBufferManager bufferManager = new RdmaBufferManager(provider)) {
            // Test basic buffer allocation
            RdmaMemoryRegion sendRegion = bufferManager.getSendRegion(4096);
            assertNotNull(sendRegion, "Send region should not be null");

Security and authentication integrated. Without any compromise with databases or data models.

All the security schemes defined in OpenAPI, including:

* HTTP Basic.
* **OAuth2** (also with **JWT tokens**). Check the tutorial on [OAuth2 with JWT](tutorial/security/oauth2-jwt.md).
* API keys in:
    * Headers.
    * Query parameters.
    * Cookies, etc.

Having **HTTPS** is very important, and quite **critical** in most cases. Most of the effort you as a developer have to put around HTTPS is just about **understanding these concepts** and how they work.

But once you know the basic information of **HTTPS for developers** you can easily combine and configure different tools to help you manage everything in a simple way.

// the content of an object has changed.
//
// In general, an S3 ETag is an MD5 checksum of the object
// content. However, there are many exceptions to this rule.
//
// # Single-part Upload
//
// In case of a basic single-part PUT operation - without server
// side encryption or object compression - the ETag of an object
// is its content MD5.
//
// # Multi-part Upload
