Import the modules installed.

Create a random secret key that will be used to sign the JWT tokens.

To generate a secure random secret key use the command:

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

And copy the output to the variable `SECRET_KEY` (don't use the one in the example).

## 处理 JWT 令牌

导入已安装的模块。

创建用于 JWT 令牌签名的随机密钥。

使用以下命令，生成安全的随机密钥：

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

然后，把生成的密钥复制到变量**SECRET_KEY**，注意，不要使用本例所示的密钥。

创建指定 JWT 令牌签名算法的变量 **ALGORITHM**，本例中的值为 `"HS256"`。

## JWT 토큰 처리

설치된 모듈을 임포트 합니다.

JWT 토큰 서명에 사용될 임의의 비밀키를 생성합니다.

안전한 임의의 비밀키를 생성하려면 다음 명령어를 사용하십시오:

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

그리고 생성한 비밀키를 복사해 변수 `SECRET_KEY`에 대입합니다. (이 예제의 변수 값을 그대로 사용하지 마십시오.)

      val connectionPreface = source.readByteString(CONNECTION_PREFACE.size.toLong())

      if (CONNECTION_PREFACE != connectionPreface) {
        throw IOException("Expected a connection header but was ${connectionPreface.utf8()}")
      }
    }
  }
