GNURLOPT_P...SLCERTTYPE(3)

💅 GNURLOPT_P...SLCERTTYPE(3) — proxy cert type core 💅

Okay bestie, quick vibe check: this page lives in the curl_easy_setopt options manual, section 3, and the main character is GNURLOPT_P...SLCERTTYPE(3). It's giving “tell curl what format my proxy client cert is in” energy, and honestly? We love a narrowly focused icon. 🎀

🌸 NAME 🌸

CURLOPT_PROXY_SSLCERTTYPE — specify the type of the proxy client SSL certificate. Slay. ✨

🦋 SYNOPSIS 🦋

#include <gnurl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLCERTTYPE, char *type);

🎀 DESCRIPTION 🎀

So you pass a pointer to a null-terminated string as the parameter, bestie. That string should be the format of your client certificate used when connecting to an HTTPS proxy. Literally that's the whole assignment. 💖

The supported formats are "PEM" and "DER", except with Secure Transport. OpenSSL (versions 0.9.3 and later) and Secure Transport (on iOS 5 or later, or OS X 10.7 or later) also support "P12" for PKCS#12-encoded files. Not me knowing the exact version lore — it's in the text, periodt. 📚✨

And good news: the application does not have to keep the string around after setting this option. Set it, forget it, live your life. 🫶

🍓 DEFAULT 🍓

The default is "PEM" — iconic, classic, default behavior. 💅

🌈 PROTOCOLS 🌈

All — no protocol gatekeeping here. All of them. 🌍✨

🔥 EXAMPLE 🔥

CURL *curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
  curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy");
  curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERT, "client.pem");
  curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERTTYPE, "PEM");
  curl_easy_setopt(curl, CURLOPT_PROXY_SSLKEY, "key.pem");
  curl_easy_setopt(curl, CURLOPT_PROXY_KEYPASSWD, "s3cret");
  ret = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
}

Obsessed with a complete little setup block. The way it just sets the URL, proxy, cert, cert type, key, key password, performs, and cleans up? Highkey tidy. ✨🧚
