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
underSerial flasher config
. - If using a different folder than
certs
for storing certificates then updateCustom Certificate Bundle Path
underComponent 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.
