✨ gnutls_x509_crt_export2(3) ✨

okay bestie, so this one lives in the gnutls manual, and it's literally the glow-up moment for your certificate — it takes that cert and turns it into something you can actually write out to a file or send somewhere. 💖

🎀 NAME 🎀

gnutls_x509_crt_export2 — API function

---

🌸 SYNOPSIS 🌸

#include <gnutls/x509.h>

int gnutls_x509_crt_export2(gnutls_x509_crt_t cert,
gnutls_x509_crt_fmt_t format, gnutls_datum_t * out);

---

🦋 ARGUMENTS 🦋

• gnutls_x509_crt_t cert — this is the certificate you're holding, the main character of the whole operation. 💅
• gnutls_x509_crt_fmt_t format — the format of the output params, girl. One of PEM or DER. pick your aesthetic ✨
• gnutls_datum_t * out — will contain a certificate that's PEM or DER encoded. this is where the magic lands, so make sure you hand it a real pointer. 🫶

---

💜 DESCRIPTION 💜

so this function will export the certificate to DER or PEM format. iconic behaviour, no cap.

the output buffer is allocated using gnutls_malloc(). so yeah, that memory is yours to deal with — it came from gnutls_malloc(), act accordingly. 🧚

and if the structure is PEM encoded, it will have a header of "BEGIN CERTIFICATE". you know the vibe, the little armour-plated fence around the base64. ⭐

---

🌈 RETURNS 🌈

In case of failure a negative error code will be returned, and 0 on success. so like — negative means something went wrong, 0 means slay. check it. 😭

---

⭐ SINCE ⭐

3.1.3 — she's been around a minute, lowkey a legend. 👑
