KRB5_FIND_PADATA(3)

💖 KRB5_FIND_PADATA(3) 💖

okay bestie, welcome to the Library Functions Manual for KRB5_FIND_PADATA — yes it's a mouthful, no we're not scared of it 🫶

✨ NAME ✨

krb5_find_padata, krb5_padata_add — the Kerberos 5 pre-authentication data handling functions 💅 like, this is where the pre-auth data gets found and where it gets added. that's the whole job. iconic behaviour fr fr.

🌸 LIBRARY 🌸

Kerberos 5 Library (libkrb5, -lkrb5) — link it and she's yours, no cap 🎀

🦋 SYNOPSIS 🦋

#include <krb5.h>

PA_DATA *
krb5_find_padata(PA_DATA *val, unsigned len, int type, int *index);

int
krb5_padata_add(krb5_context context, METHOD_DATA *md, int type,
    void *buf, size_t len);

like look at her. two whole functions. main character energy, honestly 👑

💜 DESCRIPTION 💜

🔍 krb5_find_padata()

so this one tries to find the pre-authentication data entry of type type inside the array val of length len — like a little scavenger hunt through the array, but for the exact type you asked for 🧚

here's the cute part: the search starts at the entry pointed out by *index — and heads up, that's zero based indexing, so no, 0 is not a mistake, that's just how she counts 🙈

and if the type isn't found? you get NULL back. nothing. nada. she looked, she didn't see it, that's the whole story 😭

➕ krb5_padata_add()

this one's the opposite vibe — instead of searching, she adds a pre-authentication data entry of type type pointed out by buf and len, and drops it right into md ✨

that's it. that's the function. obsessed 🍓
