在ESP32-C3芯片上，展示如何使用ESP-IDF环境的API计算MD5值

| Supported Targets | ESP32 | ESP32-C2 | ESP32-C3 | ESP32-C6 | ESP32-H2 | ESP32-S2 | ESP32-S3 | | ----------------- | ----- | -------- | -------- | -------- | -------- | -------- | -------- | # HTTP server with TLS support using mbedTLS (See the README.md file in the upper level 'examples' directory for more information about examples.) Simple HTTPS example that uses mbedTLS to establish a secure socket connection using the certificate bundle with two custom certificates added for verification: ## How to use example ### Hardware Required * A development board with ESP32/ESP32-S2/ESP32-C3 SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.) * A USB cable for power supply and programming ### 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. ## Example Output ``` I (9599) example_connect: - IPv4 address: 192.168.194.219 I (9599) example_connect: - IPv6 address: fe80:0000:0000:0000:266f:28ff:fe80:2c74, type: ESP_IP6_ADDR_IS_LINK_LOCAL I (9609) example: Seeding the random number generator I (9619) example: Attaching the certificate bundle...
