💖 NAME 💖

gnutls_x509_crt_set_subject_key_id — bestie, this is the API function that lets you set a cert's subject key ID. That's it. That's the whole job. ✨

(Also hey, hi, this page lives in the gnutls manual, section 3, and if you're here you're probably deep in X.509 land. Respect. 🫶)

🌸 SYNOPSIS 🌸

#include <gnutls/x509.h>

int gnutls_x509_crt_set_subject_key_id(gnutls_x509_crt_t cert, const
                                       void * id, size_t id_size);

Yeah, that's the whole vibe. Include the header, call the function, live your truth. 💅

🎀 ARGUMENTS 🎀

  • gnutls_x509_crt_t cert — a certificate of type gnutls_x509_crt_t. Like, the actual cert you're messing with. Your main character. 👑
  • const void * id — The key ID. Just the raw bytes, no thoughts, no commentary. 🦋
  • size_t id_size — Holds the size of the subject key ID field. So basically: how many bytes of id are we talking. 📏

✨ DESCRIPTION ✨

Okay so here's the tea: this function will set the X.509 certificate's subject key ID extension. That's it. You hand it a cert, you hand it an ID, you hand it a size, and boom — that extension is now on the certificate. Not me being obsessed with a setter function but here we are. 😭💖

🔥 RETURNS 🔥

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value. So if you get a 0, slay, you ate. If you get something negative, that's your sign to go read the error code, bestie. 🌈
