| Supported Targets | ESP32 | ESP32-C2 | ESP32-C3 | ESP32-S2 | ESP32-S3 | | ----------------- | ----- | -------- | -------- | -------- | -------- | # HTTP server with SSL support using OpenSSL This example creates a SSL server that returns a simple HTML page when you visit its root URL. See the `esp_https_server` component documentation for details. ## How to use example Before project configuration and build, be sure to set the correct chip target using `idf.py set-target `. ### Configure the project ``` idf.py menuconfig ``` Open the project configuration menu (`idf.py menuconfig`) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more details. ### 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 ``` (Replace PORT with the name of the serial port to use.) (To exit the serial monitor, type ``Ctrl-]``.) See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects. ## Certificates You will need to approve a security exception in your browser. This is because of a self signed certificate; this will be always the case, unless you preload the CA root into your browser/system as trusted. You can generate a new certificate using the OpenSSL command line tool: ``` openssl req -newkey rsa:2048 -nodes -keyout prvtkey.pem -x509 -days 3650 -out cacert.pem -subj "/CN=ESP32 HTTPS server example" ``` Expiry time and metadata fields can be adjusted in the invocation. Please see the openssl man pages (man openssl-req) for more details. It is **strongly recommended** to not reuse the example certificate in your application; it is included only for demonstration. ## Example Output ``` I (8596) example: Starting server I (8596) esp_https_server: Starting server I (8596) esp_https_server: Server listening on port 443 I (8596) example: Registering URI handlers I (8606) esp_netif_handlers: example_connect: sta ip: 192.168.194.219, mask: 255.255.255.0, gw: 192.168.194.27 I (8616) example_connect: Got IPv4 event: Interface "example_connect: sta" address: 192.168.194.219 I (9596) example_connect: Got IPv6 event: Interface "example_connect: sta" address: fe80:0000:0000:0000:266f:28ff:fe80:2c74, type: ESP_IP6_ADDR_IS_LINK_LOCAL I (9596) example_connect: Connected to example_connect: sta W (9606) wifi:idx:0 (ifx:0, ee:6d:19:60:f6:0e), tid:0, ssn:2, winSize:64 I (9616) example_connect: - IPv4 address: 192.168.194.219 I (9616) example_connect: - IPv6 address: fe80:0000:0000:0000:266f:28ff:fe80:2c74, type: ESP_IP6_ADDR_IS_LINK_LOCAL W (14426) wifi:idx:1 (ifx:0, ee:6d:19:60:f6:0e), tid:4, ssn:0, winSize:64 I (84896) esp_https_server: performing session handshake ```
