💅 gnutls_x509_cr...expiration_time(3) 💅

okay bestie, so this is one of those pages from the gnutls manual — the TLS/SSL library that literally holds the internet together, no big deal. this one's about telling a certificate when it's time to say bye-bye. ✨

✨ NAME ✨

gnutls_x509_crt_set_expiration_time — an API function, and yes she's a queen for it 👑

🎀 SYNOPSIS 🎀

#include <gnutls/x509.h>

int gnutls_x509_crt_set_expiration_time(gnutls_x509_crt_t cert, time_t exp_time);

🌸 ARGUMENTS 🌸

  • gnutls_x509_crt_t cert — a certificate of type gnutls_x509_crt_t. that's your little certificate baddie, the one you're about to give an expiry date. 🦋
  • time_t exp_time — The actual time. like, the real actual time, fr fr. this is the moment you want her to expire. ⏰

💖 DESCRIPTION 💖

This function will set the time this Certificate will expire. the way that this just straight-up hands your cert her expiration date… iconic.

and here's the lil plot twist: setting an expiration time to (time_t)-1 will set to the no well-defined expiration date value. so (time_t)-1 is the "idk bestie, no real date here" option. it's giving undefined-vibes-on-purpose. 🙈

⭐ RETURNS ⭐

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value. so if you get a 0, she ate. if you get a negative number, that's a whole red flag and you gotta check yourself. 💀
