💖 gnutls_x509_ext_import_basic_constraints 💖

okay bestie, so this one lives in the gnutls manual (you know, the whole TLS library situation) and it's version 3.8.13. It's an API function, and it's lowkey one of the cutest little X.509 helpers you'll ever meet. Let's get into it 🎀

✨ NAME ✨

gnutls_x509_ext_import_basic_constraints — it's an API function, and it does exactly one thing: pulls the basic constraints info out of a DER-encoded extension. slay 💅

🌸 SYNOPSIS 🌸

#include <gnutls/x509-ext.h>

int gnutls_x509_ext_import_basic_constraints(const gnutls_datum_t * ext,
       unsigned int * ca, int * pathlen);

🦋 ARGUMENTS 🦋

  • const gnutls_datum_t * ext — this is the DER encoded extension data, like the raw bytes, the whole vibe, unprocessed. it's giving "here's the blob, you deal with it" 💀
  • unsigned int * ca — when this comes back it'll be non zero if the CA status is true. so like, zero = not a CA, nonzero = yes queen she's a CA 👑
  • int * pathlen — the path length constraint, and listen: it gets set to -1 for no limit. so -1 is the "no cap, go wild" value fr fr 🙈

💜 DESCRIPTION 💜

So this function will return the CA status and the path length constraint exactly as they're written in the PKIX extension 2.5.29.19. That's it. That's the whole function. She's simple, she's effective, she ate ✨

🌈 RETURNS 🌈

On success, GNUTLS_E_SUCCESS (0) is returned. Otherwise you get a negative error value, which is never the vibe but at least it's honest about it 😭

⭐ SINCE ⭐

3.3.0 — so she's been around a minute, a real veteran, main character since day one 🫶
