Example Configuration ->

1. WiFi SSID: WiFi network to which your PC is also connected to.

1. WiFi Password: wifi password

The private key and certification at the example are not trusted by web browser, because they are not created by CA official, just by ourselves.

You can alse create your own private key and ceritification by "openssl at ubuntu or others".

We have the document of "ESP8266_SDKSSL_User_Manual_EN_v1.4.pdf" at "http://www.espressif.com/en/support/download/documents". By it you can gernerate the private key and certification with the fomate of ".pem"
