DNS::LD...taChain(3)

💖 NAME 💖

DNS::LDNS::DNSSecDataChain — bestie, it's a DNSSec data chain element 🦋

Like, this little cutie is one link in the DNSSec trust chain. That's the whole vibe. The page itself lives in the User Contributed Perl Documentation section, and yeah, its name is literally DNS::LDNS::DNSSecDataChain(3). Iconic, long, slay. 💅

✨ SYNOPSIS ✨

  use DNS::LDNS ':all'

  chain = new DNS::LDNS::DNSSecDataChain
  chain->print(fp)
  chain->derive_trust_tree(rr)
  chain->derive_trust_tree_time(rr, checktime)

  # Node attributes
  rrset = chain->rrset
  rrset = chain->signatures
  rrtype = chain->parent_type
  pchain = chain->parent
  rcode = chain->packet_rcode
  rrtype = chain->packet_qtype
  bool = chain->packet_nodata

okay so real quick, let me walk you through what's happening here 🫶

First you pull in the goods with use DNS::LDNS ':all' — no semicolon at the end, I know, I know, that's just how they wrote it, don't come for me, I'm just the messenger. 😭

Then you can spin up a brand-new chain object with new DNS::LDNS::DNSSecDataChain. Main character energy, fr fr. ✨

After that you've got your methods:

• chain->print(fp) — prints the chain out to fp
• chain->derive_trust_tree(rr) — derives the trust tree from rr
• chain->derive_trust_tree_time(rr, checktime) — same thing but you also hand it a checktime

And then the node attributes, aka the lil peekaboo accessors 👀:

• rrset = chain->rrset — grabs the rrset
• rrset = chain->signatures — grabs the signatures, also an rrset situation
• rrtype = chain->parent_type — gives you the parent's type as an rrtype
• pchain = chain->parent — hands back the parent chain as pchain
• rcode = chain->packet_rcode — the packet's rcode
• rrtype = chain->packet_qtype — the packet's question type, as an rrtype
• bool = chain->packet_nodata — a bool telling you about packet nodata

That's the whole menu bestie, no cap. 🍓
