-Alternatively, for ESP32 device, you can use `ESP_SSLClient` that was included in this library. It works in the same way as ESP8266's `WiFiClientSecure` and the memory used for the transmit and receive buffers are adjustable (512 to 16384).

 The useful of using `ESP_SSLClient` is it uses `PSRAM` by default, you can use it in ESP32 and ESP8266 modules that have `PSRAM` or connected to external `PSRAM`.
