I need to upgrade my ESP32 code to use a client certificate for secure communication with a remote server.

So far, I've used the

esp_http_client

library to issue the HTTP requests but as far as I've seen, this library doesn't support client certificates. What are my options?

Thanks,
Guy.

I think it does. Looking at esp_http_client.c you'll find the config struct esp_http_client_config_t, which contains ssl configuration options.

Afaik there's also an example for it in the examples folder.
