그 다음 인증서를 사용해 클라이언트와 TLS Termination Proxy는 나머지 **TCP 통신**을 어떻게 **암호화할지 결정**합니다. 이로써 **TLS 핸드셰이크** 단계가 완료됩니다.

이후 클라이언트와 서버는 TLS가 제공하는 **암호화된 TCP 연결**을 갖게 됩니다. 그리고 그 연결을 사용해 실제 **HTTP 통신**을 시작할 수 있습니다.

이것이 바로 **HTTPS**입니다. 순수(암호화되지 않은) TCP 연결 대신 **안전한 TLS 연결** 안에서 **HTTP**를 그대로 사용하는 것입니다.

/// tip | 팁

통신의 암호화는 HTTP 레벨이 아니라 **TCP 레벨**에서 일어난다는 점에 주의하세요.
