Have you had experience working with the HTTPS protocol for secure data transmission?

Yes, experience with the HTTPS protocol in C/C++ typically involves using libraries such as OpenSSL or libcurl to ensure secure data transmission over the network. HTTPS is HTTP over TLS/SSL, which encrypts data and provides server authentication.

Example of using libcurl for an HTTPS request:

#include <curl/curl.h>

int main() {
    CURL *curl = curl_easy_init();
    if(curl) {
        curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
        CURLcode res = curl_easy_perform(curl);
        if(res != CURLE_OK)
            fprintf(stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror(res));
        curl_easy_cleanup(curl);
    }
    return 0;
}

In this example, libcurl automatically handles the TLS connection, verifies certificates, and encrypts traffic.
