💖 NAME 💖

shishi_der2asn1_apreq — bestie, this is an API function and it's about to decode some DER for you ✨

It lives in the shishi manual, so if you're the kind of girl who reads man 3 pages for fun (me, obviously 💅), you're in the right place.

✨ SYNOPSIS ✨

okay so here's the vibe, literally the whole function signature, no cap:

#include <shishi.h>

Shishi_asn1 shishi_der2asn1_apreq(Shishi * handle, const char * der,
       size_t derlen);

three arguments, one return value, zero drama 🎀

🫶 ARGUMENTS 🫶

  • Shishi * handle — the shishi handle, and yes bestie you gotta get it the proper way, as allocated by shishi_init(). no homemade handles, that's not the move 🙈
  • const char * der — the input character array holding the DER encoding. it's giving "raw bytes, handle with care" 💀
  • size_t derlen — the length of that input character array with the DER encoding. yeah you have to tell it how long the thing is, it's not psychic 😭

🌸 DESCRIPTION 🌸

So what does it even do? It decodes the DER encoding of AP-REQ and creates an ASN.1 structure. That's it, that's the whole assignment. DER goes in, ASN.1 comes out, main character energy from start to finish 👑

⭐ RETURN VALUE ⭐

It returns the ASN.1 structure corresponding to the DER data. Like, you hand it the encoded situation and it hands you back the actual structure. iconic behaviour fr fr 💜

💀 REPORTING BUGS 💀

Found a bug? Don't suffer in silence, bestie, tell the people:

not me begging you to actually file the bug instead of just complaining in the group chat 🫶
