모든 보안 흐름을 구성했으므로, 이제 <abbr title="JSON 웹 토큰">JWT</abbr> 토큰과 안전한 패스워드 해싱을 사용해 애플리케이션을 실제로 안전하게 만들겠습니다.

이 코드는 실제로 애플리케이션에서 사용할 수 있으며, 패스워드 해시를 데이터베이스에 저장하는 등의 작업에 활용할 수 있습니다.

이전 장에서 멈춘 지점부터 시작해 내용을 확장해 나가겠습니다.

## JWT 알아보기 { #about-jwt }

JWT는 "JSON Web Tokens"를 의미합니다.

JSON 객체를 공백이 없는 길고 밀집된 문자열로 부호화하는 표준입니다. 다음과 같은 형태입니다:

```

  //    Imagine:
  //    guard.lock();
  //    try { /* monitor locked and guard satisfied here */ }
  //    finally { guard.unlock(); }
  // Here are Justin's design notes about this:
  //
  // This idea has come up from time to time, and I think one of my
  // earlier versions of Monitor even did something like this. I ended
  // up strongly favoring the current interface.

  private val noContextTakeover: Boolean,

  // Stateful data about the current frame.

  private var frameLength = 0L
  private var isFinalFrame = false
  private var isControlFrame = false
  private var readingCompressedMessage = false
