✨ shishi_der2asn1_asrep ✨

okay bestie, gather round, because we're diving into a lil corner of the shishi manual — yes, that shishi, the GNU one, and this particular page is the one for shishi_der2asn1_asrep(3). it's giving "niche but essential" and honestly? we love that for it. 🫶

🌸 NAME 🌸

shishi_der2asn1_asrep — it's an API function, bestie. that's the whole vibe. 💅

🎀 SYNOPSIS 🎀

first things first, you gotta pull in the header, no cap:

#include <shishi.h>

and here's the actual function signature, copy it exactly okay, don't freestyle:

Shishi_asn1 shishi_der2asn1_asrep(Shishi * handle, const char * der,
       size_t derlen);

🦋 ARGUMENTS 🦋

three lil guys walk into a function:

  • Shishi * handle — this is your shishi handle, the one you get handed to you when you call shishi_init(). it's like your VIP pass to the whole library, fr fr.
  • const char * der — an input character array holding the DER encoding. that's the raw bytes you're feeding in, bestie.
  • size_t derlen — the length of that input character array with the DER encoding. gotta tell it how big your lil byte blob is, otherwise how would it know?? 😭

💖 DESCRIPTION 💖

so what does this actually do? it takes the DER encoding of an AS-REP and decodes it, creating an ASN.1 structure out of it. that's it, that's the whole job. decode → structure. iconic behaviour honestly. ✨

⭐ RETURN VALUE ⭐

it hands you back an ASN.1 structure that corresponds to your DER data. that's the treasure at the end of the rainbow. 🌈
