安全性：SecKeychainSearchCopyNext :(通过终端的Wi-Fi密码）

我试图通过终端[1]以明文方式查看（作为root）wifi密码，但得到以下错误：

sh-3.2# security find-generic-password -ga "ROUTER-NAME-HERE"
security: SecKeychainSearchCopyNext: The specified item could not be found in the keychain.

sh-3.2# security find-generic-password -a lily -s "ROUTER-NAME-HERE" -g
security: SecKeychainSearchCopyNext: The specified item could not be found in the keychain.

所以我用谷歌搜索错误[2]，但我没有找到答案有帮助。

显示与此类似的无线网络的WiFi密码，将“wifinetworkname”替换为引号中的无线网络名称：
