💖 NAME 💖

gnutls_x509_crt_get_private_key_usage_period — bestie, this is an API function, and it's here to tell you when a certificate's private key is allowed to do its little thing ✨

It lives in the gnutls manual, section 3, so if you were hunting for it in the man pages, you found her 🎀

✨ SYNOPSIS ✨

#include <gnutls/x509.h>

int gnutls_x509_crt_get_private_key_usage_period(gnutls_x509_crt_t cert,
time_t * activation, time_t * expiration, unsigned int * critical);

okay so it's literally just one include and one function call, we love a low-effort baddie 🫶

🎀 ARGUMENTS 🎀

  • gnutls_x509_crt_t cert — should contain a gnutls_x509_crt_t type. like, that's the cert we're snooping on 💅
  • time_t * activation — the activation time ⏰
  • time_t * expiration — the expiration time ⌛
  • unsigned int * critical — the extension status 👑

🦋 DESCRIPTION 🦋

so what does she actually do?? This function will return the expiration and activation times of the private key of the certificate 🔥

And it gets those from the PKIX extension 2.5.29.16 — so that extension has to be present, no cap. If it's not there, girl, she's not gonna magic it out of thin air 🙈

⭐ RETURNS ⭐

  • On success, GNUTLS_E_SUCCESS (0) is returned 🎉
  • GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the extension is not present 😭 (yep, told you)
  • otherwise a negative error value 💀
