✨ shishi_tkt_initial_p ✨

okay bestie, gather round 💖 this is a page from the shishi manual, section 3 — and today's main character is shishi_tkt_initial_p, an API function that's literally just here to answer one (1) very specific question for you. no cap.

🌸 SYNOPSIS 🌸

#include <shishi.h>

int shishi_tkt_initial_p(Shishi_tkt * tkt);

like, that's the whole thing. short king energy 👑

🎀 ARGUMENTS 🎀

  • Shishi_tkt * tkt — your input variable with ticket info in it. that's the tea you're handing over for inspection 🍓

💅 DESCRIPTION 💅

so what does it actually do? it figures out whether the ticket was issued using the AS exchange. periodt.

now let's talk about the INITIAL flag, because this is the part that matters and it's giving very much "important lore" 🔥

the INITIAL flag says that a ticket was issued using the AS protocol, rather than issued based on a ticket-granting ticket. two very different origin stories, bestie 🌈

and why do we care?? because application servers that want to require the demonstrated knowledge of a client's secret key — think, like, a password-changing program as the classic example — can insist that this flag be set in any tickets they accept. and by doing that, they get to be assured that the client's key was recently presented to the application client. so it's not just a vibe check, it's an actual security vibe check 🫶

⭐ RETURN VALUE ⭐

returns non-0 iff the initial flag is set in the ticket. so:

  • non-0 → yep, flag's set, it's initial 💖
  • 0 → nope, not initial 🙈
