✨ NAME ✨

gnutls_dh_params_export2_pkcs3 — bestie, it's an API function 💅 and it's here to turn your DH params into a PKCS3 DHParams glow-up ✨

---

🌸 SYNOPSIS 🌸

#include <gnutls/gnutls.h>

int gnutls_dh_params_export2_pkcs3(gnutls_dh_params_t params,
gnutls_x509_crt_fmt_t format, gnutls_datum_t * out);

---

🎀 ARGUMENTS 🎀

• gnutls_dh_params_t params — okay so this one holds the DH parameters. It's the whole point of the operation, the main character fr 👑
• gnutls_x509_crt_fmt_t format — the format of output params. One of PEM or DER. Pick your vibe, bestie, you literally can't have both 💜
• gnutls_datum_t * out — this is where the output lives. It will contain a PKCS3 DHParams structure, PEM or DER encoded, depending on what you asked for above 🦋

---

🧚 DESCRIPTION 🧚

So like. This function will export the given dh parameters to a PKCS3 DHParams structure. No cap. And get this — this is the format generated by the "openssl dhparam" tool 🔥 so if you're interoperating with that, you're eating, you're slaying, you're done.

The data in out will be allocated using gnutls_malloc(). Remember that — it's yours to free later, so don't ghost it 🙈

If the structure is PEM encoded, it will have a header of "BEGIN DH PARAMETERS". Iconic header, honestly. The way that header just announces itself 💖

---

⭐ RETURNS ⭐

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned. So like, zero = slay, negative = not slay 😭 check your return values bestie, always.
