💖 ldns(3) — Library Functions Manual 💖

okay bestie, welcome to ldns(3) — it's a Library Functions Manual situation and we're about to talk about verifying signature data buffers. yes. we're doing crypto. slay. 🎀

---

✨ NAME ✨

ldns_verify_rrsig_dsa, ldns_verify_rrsig_rsasha1, ldns_verify_rrsig_rsamd5 — verify signature data buffers 💅

---

🌸 SYNOPSIS 🌸

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

#include <ldns/ldns.h>

ldns_status ldns_verify_rrsig_dsa(ldns_buffer *sig, ldns_buffer *rrset,
ldns_buffer *key);

ldns_status ldns_verify_rrsig_rsasha1(ldns_buffer *sig, ldns_buffer
*rrset, ldns_buffer *key);

ldns_status ldns_verify_rrsig_rsamd5(ldns_buffer *sig, ldns_buffer
*rrset, ldns_buffer *key);

like yes, three functions, same shape, three different algorithms. the way that they all take the exact same three buffers… iconic honestly. 🦋

🌈 DESCRIPTION 🌈

okay so. all three of these are verify girlies. they take a buffer of signature data, a buffer of rrset data, and a buffer of key data, and they check whether the sig actually checks out. no cap. 🔥

• ldns_verify_rrsig_dsa() — verifies a buffer with signature data (DSA) for a buffer with rrset data with a buffer with key data.
  • sig: the signature data
  • rrset: the rrset data, sorted and processed for verification
  • key: the key data
• ldns_verify_rrsig_rsasha1() — verifies a buffer with signature data (RSASHA1) for a buffer with rrset data with a buffer with key data.
  • sig: the signature data
  • rrset: the rrset data, sorted and processed for verification
  • key: the key data
• ldns_verify_rrsig_rsamd5() — verifies a buffer with signature data (RSAMD5) for a buffer with rrset data with a buffer with key data.
  • sig: the signature data
  • rrset: the rrset data, sorted and processed for verification
  • key: the key data

bestie pls note: the rrset buffer has to be sorted and processed for verification before you hand it over. that's not optional, that's the whole vibe. 🫶

This manpage was automatically generated from the ldns source code. yes, a machine wrote it. and now a very enthusiastic teenager rewrote it. the circle of life. 🦋

and that's the whole page bestie!! this one's from 30 May 2006, it lives in ldns(3), and it ate. go verify some signatures, main character. 🎀✨💖
