GNUTLS_X509_CRQ_SET_EXTENSION_BY_OID(3)

✨ NAME ✨

gnutls_x509_crq_set_extension_by_oid — bestie, this is the API function that slaps an extension onto a certificate request 💅 (and yes, it lives in the gnutls manual, section 3, iykyk)

---

🌸 SYNOPSIS 🌸

#include <gnutls/x509.h>

int gnutls_x509_crq_set_extension_by_oid(gnutls_x509_crq_t crq, const
char * oid, const void * buf, size_t sizeof_buf, unsigned int critical);

okay so literally just include the header and you're in 🫶

---

🎀 ARGUMENTS 🎀

• gnutls_x509_crq_t crq — a certificate request of type gnutls_x509_crq_t. this is the main character you're decorating ✨
• const char * oid — holds an Object Identifier as a null terminated string. it's giving "who dis extension" energy 👑
• const void * buf — a pointer to DER encoded data. the actual contents, raw and real 🙈
• size_t sizeof_buf — holds the size of buf. like, how much data are we working with, fr fr
• unsigned int critical — should be non-zero if the extension is to be marked as critical ⚠️ non-zero = critical, zero = not critical, no in-between bestie

---

💖 DESCRIPTION 💖

This function will set an the extension, by the specified OID, in the certificate request. The extension data should be binary data DER encoded.

so basically: you hand it the crq, you hand it the OID of the extension you want, you hand it the DER-encoded bytes, and boom — the extension is set. the way that the data must be DER encoded though... no cap, it's not optional. binary DER or nothing 🦋

---

⭐ RETURNS ⭐

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value. so like... zero is the slay outcome, anything negative means something went sideways 😭
