✨ shishi_der2asn1 ✨

okay bestie so this is a page from the shishi manual — section 3, library calls, the good stuff 💅 — and it's literally just one tiny little function that does one tiny little glow-up. buckle up, it's a short one 🎀

🌸 NAME 🌸

shishi_der2asn1 — the API function that turns your raw DER bytes into a whole ASN.1 situation 💖

🦋 SYNOPSIS 🦋

#include <shishi.h>

Shishi_asn1 shishi_der2asn1(Shishi * handle, const char * der, size_t
derlen);

💜 ARGUMENTS 💜

  • Shishi * handle — your shishi handle, bestie. the one you got from shishi_init(). no handle, no party 🙈
  • const char * der — the input character array holding the DER encoding. this is the raw material, the before-picture 📸
  • size_t derlen — the length of that input character array with the DER encoding. like, how many bytes are we talking. you gotta tell her 🫶

🌈 DESCRIPTION 🌈

okay so the whole vibe here: you hand her arbitrary DER data from a packet, and she converts it into an ASN.1 type. that's it. that's the function. she takes the chaotic little byte blob and gives it structure, main character energy fr fr ✨

⭐ RETURN VALUE ⭐

she returns a newly allocated ASN.1 thing corresponding to your DER data 💖

and if it doesn't work out? she returns NULL. on failure. that's the whole story 😭

💀 REPORTING BUGS 💀

found a bug? not the vibe. report it to <bug-shishi@gnu.org> 📧

and that's the page, bestie!! this one's from shishi version 1.0.3, filed under shishi_der2asn1(3) — mwah, go convert some DER, slay 🎀💖🌈
