💖 shishi_kdcreq_validate_p — the manual page, bestie edition 💖

okay so real talk, this is a page from the shishi manual (section 3, the library-function girlies 🎀), and it's all about one tiny little function that answers one tiny little question. let's get into it. ✨

✨ NAME ✨

shishi_kdcreq_validate_p — it's an API function, bestie. that's the whole job description. 💅

🌸 SYNOPSIS 🌸

#include <shishi.h>

int shishi_kdcreq_validate_p(Shishi * handle, Shishi_asn1 kdcreq);

look at her. two args, one int return, zero drama. iconic. 👑

🦋 ARGUMENTS 🦋

  • Shishi * handle — your shishi handle, the one you got from shishi_init(). she's the main character here, pls be nice to her. 🫶
  • Shishi_asn1 kdcreq — the KDC-REQ variable we're gonna reach into to grab the kdc-options field from. that's the vibe. 💖

💅 DESCRIPTION 💅

so basically: this function determines whether the KDC-Option validate flag is set. yes/no. set or not set. that's it, that's the whole thing. ✨

now for the lore, because this flag has lore: the VALIDATE option is used only by the ticket-granting service. no cap. 🎟️

what does it mean though? the VALIDATE option is saying "hey, this request is here to validate a postdated ticket." and here's the thing — it will only be honored if all of these are true:

  • the ticket presented is postdated,
  • it presently has its INVALID flag set,
  • and it would be otherwise usable at this time.
🚨 important, and I mean it: a ticket cannot be validated before its starttime. periodt. don't even try it. 💀

and one more detail, because details are everything: the ticket presented for validation is encrypted in the key of the server for which it is valid, and it gets passed in the padata field as part of the authentication header. slay. 🔥

⭐ RETURN VALUE ⭐

Returns non-0 iff the validate flag is set in KDC-REQ. that's the whole answer. non-zero = yes bestie, zero = nope. 🌈
