# 解释信息的安全意义：
#
# - 如果证书的 Common Name 与请求的 IP 不匹配（如这里的 'crnn.f3322.net'），
# 则可能表明服务隐藏了真实身份或存在配置错误，这在后续攻击中可以作为信息收集的一部分。
#
# - TLS 连接信息（如 TLS1.3 和加密套件）有助于判断是否存在弱加密或旧版协议问题。
#
# - HTTP 状态和 Content-Type 帮助确认返回的是一个合法的 Web 服务，
# 而 HTML Title 暗示了实际运行的是 SoftEther VPN Server，可能存在默认配置或已知漏洞。
#
# 这些信息可以作为进一步探测、漏洞验证和渗透测试的依据。
