💖 gnutls_x509_ext_import_proxy — bestie edition 💖

okay so this is a page from the gnutls manual, and it's literally all about pulling the deets out of a proxy certificate extension. no cap, it's a whole vibe. let's get into it 🦋

✨ NAME ✨

gnutls_x509_ext_import_proxy — the API function that yoinks info out of a proxy cert extension 💅

---

🎀 SYNOPSIS 🎀

#include <gnutls/x509-ext.h>

int gnutls_x509_ext_import_proxy(const gnutls_datum_t * ext, int *
pathlen, char ** policyLanguage, char ** policy, size_t *
sizeof_policy);

---

🌸 ARGUMENTS 🌸

• const gnutls_datum_t * ext — bestie this is the DER encoded extension data, the raw material, the main character of the input 🫶
• int * pathlen — pointer to an output integer that tells you the path length. it may be NULL, so it's giving optional. here's the tea: non-negative error codes mean there's a present pCPathLenConstraint field and that's the actual value, and -1 means the field is literally absent, she's not there 😭
• char ** policyLanguage — output variable holding the OID of the policy language ✨
• char ** policy — output variable holding the policy data itself 👑
• size_t * sizeof_policy — output variable with the size of the policy data, because we need to know how much policy we're dealing with 📏

---

💖 DESCRIPTION 💖

so this function returns the information from a proxy certificate extension. it reads the ProxyCertInfo X.509 extension, which is 1.3.6.1.5.5.7.1.14 — yes, that exact OID, copy it carefully bestie, character for character, iykyk 🔥

⚠️ IMPORTANT: the policyLanguage and policy values must be deinitialized using gnutls_free() after use. don't leave them hanging, that's rude and also a memory leak 💀

---

⭐ RETURNS ⭐

on success, GNUTLS_E_SUCCESS (0) is returned. otherwise you get a negative error value. that's it, that's the whole vibe check 🌈

---
