✨ ldns(3) — the library functions manual, bestie edition ✨

okay so this is a page from the ldns manual, section 3 (that's the "library functions" girlies 💅). today's episode: calculating keytags, fr fr. let's get into it 🎀

🌸 NAME 🌸

ldns_calc_keytag, ldns_calc_keytag_raw — calculate ldns keytag

---

✨ SYNOPSIS ✨

#include <stdint.h>
#include <stdbool.h>

#include <ldns/ldns.h>

uint16_t ldns_calc_keytag(const ldns_rr *key);

uint16_t ldns_calc_keytag_raw(const uint8_t* key, size_t keysize);

like, just include those headers and you're set 🫶

---

💖 DESCRIPTION 💖

ldns_calc_keytag() calculates a keytag of a key for use in DNSSEC. she's giving "i do one thing and i do it well" 💅

• key: the key as an RR to use for the calc.
• Returns the keytag

ldns_calc_keytag_raw() Calculates keytag of DNSSEC key, operates on wireformat rdata. lowkey the same energy, just rawer 🔥

• key: the key as uncompressed wireformat rdata.
• keysize: length of key data.
• Returns the keytag

not me noticing both of these just... hand you back the keytag. that's it. that's the whole job. iconic. 👑
