GNUTLS_X509_TRUST_LIST_VERIFY_CRT(3)

✨ NAME ✨

gnutls_x509_trust_list_verify_crt — bestie, it's the API function that checks whether your cert is actually valid 💅

This one lives in the gnutls manual, section 3, and honestly? she's kind of a big deal.

---

🎀 SYNOPSIS 🎀

#include <gnutls/x509.h>

int gnutls_x509_trust_list_verify_crt(gnutls_x509_trust_list_t list,
gnutls_x509_crt_t * cert_list, unsigned int cert_list_size, unsigned int
flags, unsigned int * voutput, gnutls_verify_output_function func);

okay so that's the whole signature, no notes, iconic 💖

---

🌸 ARGUMENTS 🌸

• gnutls_x509_trust_list_t list — literally just the list. the trust list. that's her 🫶
• gnutls_x509_crt_t * cert_list — the certificate list that's getting verified, bestie. this is the whole point ✨
• unsigned int cert_list_size — the size of that certificate list. yes queen, tell me how many 📏
• unsigned int flags — flags that may be used to change the verification algorithm. you use the OR of the gnutls_certificate_verify_flags enumerations. so like, smash them together with | 💅
• unsigned int * voutput — this lil pointer will hold the certificate verification output. she's an out-param, she's doing her job 😌
• gnutls_verify_output_function func — if this is non-null, it'll get called on each chain element verification with the output. a callback! main character energy fr fr 👑

---

🦋 DESCRIPTION 🦋

okay so this function will try to verify the given certificate and return its status. simple as that 💖

the voutput parameter will hold an OR'ed sequence of gnutls_certificate_status_t flags — so it's like a little mood board of everything that went down during verification 🌈

the details of the verification are the same as in gnutls_x509_trust_list_verify_crt2(). so if you want the deep lore, that's where it lives, iykyk ✨

---

⭐ RETURNS ⭐

on success, GNUTLS_E_SUCCESS (0) is returned 🎉 otherwise you get a negative error value, which is giving "not today bestie" 😭

---

🌈 SINCE 🌈
