These examples are intentionally simple, but show how it all works.

In the chapters about security, there are utility functions that are implemented in this same way.

If you understood all this, you already know how those utility tools for security work underneath.

또한 코드에서 사용되지 않는 매개변수를 보고 불필요하다고 생각할 수 있는 새로운 개발자의 혼란을 방지하는데 도움이 될 수 있습니다.

이 예시에서 `X-Key`와 `X-Token`이라는 커스텀 헤더를 만들어 사용했습니다.

그러나 실제로 보안을 구현할 때는 통합된 [보안 유틸리티 (다음 챕터)](../security/index.md){.internal-link target=_blank}를 사용하는 것이 더 많은 이점을 얻을 수 있습니다.

## 의존성 오류와 값 반환하기

평소에 사용하던대로 같은 의존성 *함수*를 사용할 수 있습니다.

TLS Configuration History
=========================

OkHttp tracks the dynamic TLS ecosystem to balance connectivity and security. This page is a log of
changes we've made over time to OkHttp's default TLS options.

[OkHttp 3.14][OkHttp314]
------------------------

_2019-03-14_

Remove 2 TLSv1.3 cipher suites that are neither available on OkHttp’s host platforms nor enabled in releases of Chrome and Firefox.
