 short_description: "密码暴力破解工具，支持多种协议和服务"
 description: |
-  Hydra是一个快速的网络登录破解工具，支持多种协议和服务的密码暴力破解。
+  Hydra 是网络登录口令爆破工具，支持 SSH、FTP、HTTP、SMB 等多种协议。
 
-  **主要功能：**
-  - 支持多种协议（SSH, FTP, HTTP, SMB等）
-  - 快速并行破解
-  - 支持用户名和密码字典
-  - 可恢复的会话
+  **调用约定（必读）：**
+  - 必须提供 **用户名**：`username`（-l）或 `username_file`（-L）至少其一
+  - 必须提供 **口令**：`password`（-p）、`password_file`（-P）或 `-C`（经 `additional_args`）至少其一
+  - **先用小字典试跑**（几十～几百条），确认目标可达再扩大；禁止默认使用 rockyou 等超大字典
+  - 默认已启用：找到即停（-f）、并行 4（-t）、忽略 restore（-I）；长任务请设 `output_file`
 
-  **使用场景：**
-  - 密码强度测试
-  - 渗透测试
-  - 安全评估
-  - 弱密码检测
+  **CLI 顺序：** `hydra [选项] <target> <service>`（本工具已按此顺序组参，勿把 target 写在选项前）
+
+  **使用场景：** 授权环境下的弱口令检测、密码强度评估
+
+  **注意：** 仅用于已授权目标；对无响应目标请减小 `wait_time` 或缩小字典，避免长时间挂起。
