✨ shishi_kdcreq_get_padata ✨

okay bestie, so this is a page out of the shishi manual (that's the GNU Shishi Kerberos-ish situation 💅) and it's literally just one little function that goes digging for pre-auth data. stay with me, it's giving main character energy 🎀

🌸 SYNOPSIS 🌸

#include <shishi.h>

int shishi_kdcreq_get_padata(Shishi * handle, Shishi_asn1 kdcreq,
       Shishi_padata_type padatatype, char ** out, size_t * outlen);

🫶 ARGUMENTS 🫶

  • Shishi * handle — the shishi handle, and it's gotta be one that was allocated by shishi_init(). no bootleg handles, bestie.
  • Shishi_asn1 kdcreq — the KDC-REQ you're pulling PA-DATA out of. it's the source, the moment, the origin story 🦋
  • Shishi_padata_type padatatype — which type of PA-DATA you want, peek at Shishi_padata_type for the whole menu.
  • char ** out — the output array, and it comes with a freshly allocated PA-DATA value inside. new in the wrapper, no cap ✨
  • size_t * outlen — the size of that output array with the PA-DATA value. the receipts, basically.

💖 DESCRIPTION 💖

So what it does: it gets the pre authentication data (PA-DATA) from a KDC-REQ. 📬

And why do we care? Because pre authentication data is literally how you pass all kinds of info over to the KDC — like, in the case of a SHISHI_PA_TGS_REQ padatatype, it's the AP-REQ that authenticates the user so they can get the ticket. it's the little VIP pass that says "yes it's me, let me in" 👑

⭐ RETURN VALUE ⭐

Returns SHISHI_OK iff successful. that's it. that's the whole vibe check. if you get SHISHI_OK you ate. 🔥
