✨ gnutls_pubkey_export2 ✨

okay bestie, gather round, because this one lives in the gnutls manual (yes, the whole big Texinfo situation, we'll get there) and it is genuinely one of the cutest little utility functions in the abstract.h family. it's giving "let me hand you your public key in a tidy format" energy and honestly? obsessed. 🎀

💖 NAME 💖

gnutls_pubkey_export2 — an API function 🦋

🌸 SYNOPSIS 🌸

#include <gnutls/abstract.h>

int gnutls_pubkey_export2(gnutls_pubkey_t key, gnutls_x509_crt_fmt_t
format, gnutls_datum_t * out);

like yes, it's a mouthful, but look at her, she's doing her best and she's slaying 💅

🫶 ARGUMENTS 🫶

  • gnutls_pubkey_t key — holds the certificate. that's the thing you're exporting from, your little key holder, your main character ✨
  • gnutls_x509_crt_fmt_t format — the format of the output params, and it's one of PEM or DER. no in-between, no third option, pick a lane bestie 🌈
  • gnutls_datum_t * out — this is where the goods land. it will contain a certificate, PEM or DER encoded 🎀

💜 DESCRIPTION 💜

so here's the tea: this function will export the public key to DER or PEM format. periodt.

and what's actually inside that exported data? it's the SubjectPublicKeyInfo X.509 structure. that's the whole vibe. no cap.

the output buffer is allocated using gnutls_malloc(), so like, that memory is yours to deal with (iykyk) 💀

and if the structure is PEM encoded, it will have a header of "BEGIN CERTIFICATE". iconic header, honestly. 🔥

⭐ RETURNS ⭐

in case of failure, a negative error code gets returned. on success you get 0. simple as that, bestie, no plot twists 🙈

🦋 SINCE 🦋

3.1.3 — an elder, but a beloved one 👑
