/*

|
|
HTTP over TLS (HTTPS) example sketch
|
||
|
|
|
||
|
|
This example demonstrates how to use
|
||
|
|
WiFiClientSecure class to access HTTPS API.
|
||
|
|
We fetch and display the status of
|
||
|
|
esp8266/Arduino project continuous integration
|
||
|
|
build.
|
||
|
|
|
||
|
|
Limitations:
|
||
|
|
only RSA certificates
|
||
|
|
no support of Perfect Forward Secrecy (PFS)
|
||
|
|
TLSv1.2 is supported since version 2.4.0-rc1
|
||
|

Created by Ivan Grokhotkov, 2015.

This example is in public domain.
