SSH 异步暴力破解器 (AsyncSSH + Paramiko 双引擎)
================================================
- 异步高并发：asyncio + asyncssh，单机可达 500+ 并发
- 智能字典：内置 Top200 常用凭证 + 自定义字典文件
- 多端口支持：22, 2222, 22222 等非标端口自动探测
- 断点续传：支持中断后从上次位置继续
- 成功凭证自动写入 JSON/CSV，可对接 02_账号密码管理
- 速率控制：避免触发目标 fail2ban / DenyHosts

用法:
    # 单IP测试
    python3 ssh_bruter.py --target 192.168.1.100

    # 批量IP（从文件读取，每行一个IP或IP:port）
    python3 ssh_bruter.py --targets targets.txt

    # 指定自定义字典
    python3 ssh_bruter.py --target 192.168.1.100 --userdict users.txt --passdict passwords.txt

    # 从扫描结果导入（01_扫描模块输出的JSON）
    python3 ssh_bruter.py --from-scan ../01_扫描模块/results/scan_results.json

    # 高并发模式
    python3 ssh_bruter.py --targets targets.txt --concurrency 300 --timeout 8

依赖安装:
    pip install asyncssh paramiko aiofiles
