✨ gnutls_x509_ext_import_subject_key_id ✨

okay bestie, so this one lives in the gnutls manual, section 3, under the very cute abbreviated name gnutls_x509_ex..._subject_key_id(3) (yes the middle got eaten, it's giving ✂️, we move on). It's an API function, and it's about pulling a subject key ID out of a DER extension. Let's go 💅

🦋 NAME 🦋

gnutls_x509_ext_import_subject_key_id — it's an API function, periodt.

🌸 SYNOPSIS 🌸

#include <gnutls/x509-ext.h>

int gnutls_x509_ext_import_subject_key_id(const gnutls_datum_t * ext,
gnutls_datum_t * id);

like. it's so simple. look at her. iconic 🎀

💖 ARGUMENTS 💖

  • const gnutls_datum_t * ext — this is a DER encoded extension. that's the vibe. that's all it is. DER. encoded. extension. no cap.
  • gnutls_datum_t * id — she's the output, bestie 🫶 this is where the subject key ID ends up living. will contain the subject key ID.

✨ DESCRIPTION ✨

so what does she actually DO. she will return the subject key ID stored in the provided SubjectKeyIdentifier extension. that's the whole job. the way she just... does it 😭

and listen — the ID gets allocated using gnutls_malloc(). so it's yours, okay? you own that memory. it's your child now. take care of it 🧚

⭐ RETURNS ⭐

  • on success, GNUTLS_E_SUCCESS (0) is returned 🎉 slay
  • GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the extension is not present — like, she looked, bestie, and it's just not there 💀
  • otherwise, a negative error value. yeah. that one's on you, fr fr.

🌈 SINCE 🌈

3.3.0 — she's been around a minute, an elder icon 👑
