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).

	"github.com/minio/minio/internal/hash"
	xhttp "github.com/minio/minio/internal/http"
)

func getDefaultOpts(header http.Header, copySource bool, metadata map[string]string) (opts ObjectOptions, err error) {
	var clientKey [32]byte
	var sse encrypt.ServerSide

	opts = ObjectOptions{UserDefined: metadata}
	if v, ok := header[xhttp.MinIOSourceProxyRequest]; ok {
		opts.ProxyHeaderSet = true
		opts.ProxyRequest = strings.Join(v, "") == "true"
	}

			[]string{}, // only need DN, so pass no attributes here
			nil,
		)

		searchResult, err := conn.Search(searchRequest)
		if err != nil {
			// Object does not exist error?
			if ldap.IsErrorWithCode(err, 32) {
				ndn, err := ldap.ParseDN(dn)
				if err != nil {
					return nil, err
				}
				nonExistentUsers = append(nonExistentUsers, ndn.String())
				continue
			}
			return nil, err
		}

## 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"`。

创建设置令牌过期时间的变量。

	{dataBlocks: 2, onDisks: 4, offDisks: 0, blocksize: int64(blockSizeV2), data: int64(oneMiByte), offset: -1, length: 3, algorithm: DefaultBitrotAlgorithm, shouldFail: true, shouldFailQuorum: false},                                              // 32

          alternatingKeysAndValues[outKeyIndex ^ 1] = value;
        }
        outI++;
      }
      return outI == n ? hashTable : new Object[] {hashTable, outI, duplicateKey};
    } else {
      /*
       * Use 32 bits per entry.
       */
      int[] hashTable = new int[tableSize];
      Arrays.fill(hashTable, ABSENT);

      int outI = 0;
      entries:
      for (int i = 0; i < n; i++) {
