💅 Net::DNS::SEC::ECDSA — like, the whole page, bestie

okay so before we even start: this is a section 3 manpage, it lives in the User Contributed Perl Documentation manual, and its whole government name is Net::DNS::SEC::ECDSA. yes the header up top gets truncated to Net::DN...::ECDSA(3) because terminals are haters. anyway. 🎀

✨ NAME ✨

Net::DNS::SEC::ECDSA — the DNSSEC ECDSA digital signature algorithm. that's it, that's the vibe. she signs, she verifies, she slays. 🔥

🌸 SYNOPSIS 🌸

require Net::DNS::SEC::ECDSA;

$signature = Net::DNS::SEC::ECDSA->sign( $sigdata, $private );

$validated = Net::DNS::SEC::ECDSA->verify( $sigdata, $keyrr, $sigbin );

literally copy-paste that and you're in your era ✨

🦋 DESCRIPTION 🦋

so this module is the implementation of the ECDSA elliptic curve digital signature generation and verification procedures. it does the two things. the signing thing and the verifying thing. iconic behavior honestly. 👑

✨ sign ✨

$signature = Net::DNS::SEC::ECDSA->sign( $sigdata, $private );

generates the wire-format signature from the sigdata octet string and the appropriate private key object. yes she takes your sigdata AND your private key and gives you a signature. main character energy fr fr. 🫶

💜 verify 💜

$validated = Net::DNS::SEC::ECDSA->verify( $sigdata, $keyrr, $sigbin );

verifies the signature over the sigdata octet string using the specified public key resource record. so it's like "is this signature actually valid, or are we being lied to" and the answer comes back as $validated. vibe check passed or not, no cap. 💀
