/*
|
|
* 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.
