✨ shishi_tkt_invalid_p ✨

okay so bestie, welcome to the shishi manual, section 3 (that's the library functions girlies 💅). today's main character is shishi_tkt_invalid_p and she is literally here to answer one (1) question: is this ticket valid or not. no cap.

🌸 NAME 🌸

shishi_tkt_invalid_p — an API function, and yes she is exactly as iconic as she sounds 🎀

🦋 SYNOPSIS 🦋

#include <shishi.h>

int shishi_tkt_invalid_p(Shishi_tkt * tkt);

💜 ARGUMENTS 💜

  • Shishi_tkt * tkt — your input variable holding the ticket info, bestie. she's the one we're vibe-checking. 🫶

✨ DESCRIPTION ✨

So what does she do? She determines if a ticket is invalid. that's it, that's the function. 🎯

Now let's talk about the INVALID flag, because it's giving serious business. The INVALID flag indicates that a ticket is invalid. Application servers MUST reject tickets which have this flag set — no exceptions, no negotiating, periodt. 💀

A postdated ticket will be issued in this form, iykyk. Invalid tickets MUST be validated by the KDC before use, by presenting them to the KDC in a TGS request with the VALIDATE option specified. and the KDC will only validate tickets after their starttime has passed — she's picky like that. ⏰

Why all the drama? The validation is required so that postdated tickets which have been stolen before their starttime can be rendered permanently invalid (through a hot-list mechanism). yes bestie, the hot-list is the villain origin story. 🔥

💖 RETURN VALUE 💖

Returns non-0 iff the invalid flag is set in the ticket. so like, truthy = bad vibes, falsy = we're so back. 🌈
