En utilisant les identifiants :

Nom d'utilisateur : `johndoe`
Mot de passe : `secret`

Remarquez qu'à aucun endroit du code le mot de passe en clair « secret » n'apparaît, nous n'avons que la version hachée.

/**
 * API access to the <a href="https://api.slack.com/apps">Slack API</a> as an application. One

 *
 * <p>You must configure your Slack API OAuth and Permissions page with a localhost URL like {@code

Example: Limit a MinIO cluster to accept at max 1600 simultaneous S3 API requests across all nodes of the cluster.

```sh
export MINIO_API_REQUESTS_MAX=1600
export MINIO_ROOT_USER=your-access-key
export MINIO_ROOT_PASSWORD=your-secret-key
minio server http://server{1...8}/mnt/hdd{1...16}
```

or

```sh
mc admin config set myminio/ api requests_max=1600
mc admin service restart myminio/
```

 *   // If this is preemptive auth, use a preemptive credential.
 *   if (challenge.scheme().equalsIgnoreCase("OkHttp-Preemptive")) {
 *     return response.request().newBuilder()
 *         .header("Proxy-Authorization", "secret")
 *         .build();
 *   }
 * }
 * return null; // Didn't find a preemptive auth scheme.
 * ```

        String originalParams = "config.timeout=30\npassword=secret\nclient.host=localhost";

        // First parse
        Map<String, String> parsed = ParameterUtil.parse(originalParams);
        assertEquals(3, parsed.size());
        assertEquals("secret", parsed.get("password"));

        // Then encrypt
        String encrypted = ParameterUtil.encrypt(originalParams);

你會看到這樣的介面：

用和先前相同的方式授權應用。

使用下列認證資訊：

Username: `johndoe`
Password: `secret`

/// check | 檢查

注意在程式碼中完全沒有明文密碼「`secret`」，我們只有雜湊後的版本。
