HTTPS x509 Bundle Example

This example shows how to use the ESP certificate bundle utility to embed a bundle of x509 certificates and use them to establish a simple HTTPS connection over a secure connection. The path of the certificates are specified using menuconfig.

See the README.md file in the upper level 'examples' directory for more information about examples.

Example workflow

ESP TLS is initialized with the certificate bundle option enabled.
The application loops through the given URLs, establishing a secure TLS connection to all of them, verifying the server certificate included.

Configure the project

Open the project configuration menu (idf.py menuconfig)
Configure Wi-Fi or Ethernet under "Example Connection Configuration" menu. See "Establishing Wi-Fi or Ethernet Connection" section in examples/protocols/README.md for more details.
When using Make build system, set Default serial port under Serial flasher config.
If using a different folder than certs for storing certificates then update Custom Certificate Bundle Path under Component config - mbedTLS - Certificate Bundle

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT flash monitor

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
