💖 Net::DN...:ZONEMD(3) — the glow-up era 💖

okay so this is from the User Contributed Perl Documentation corner of the universe, and bestie, it's literally the manual page for Net::DNS::RR::ZONEMD. yes the name is abbreviated with dots, no I don't know why, it's giving mysterious. 🎀

✨ NAME ✨

Net::DNS::RR::ZONEMD — the DNS ZONEMD resource record. that's it, that's the whole name section, she's concise. 👑

🌸 SYNOPSIS 🌸

like, just look at her:

        use Net::DNS;
        $rr = Net::DNS::RR->new("example.com. ZONEMD 2018031500 1 1
                FEBE3D4CE2EC2FFA4BA99D46CD69D6D29711E55217057BEE
               7EB1A7B641A47BA7FED2DD5B97AE499FAFA4F22C6BD647DE");

one use, one constructor call, and a digest so long it needs its own lines. main character energy, honestly. 🦋

💅 DESCRIPTION 💅

this is the class for the DNS Zone Message Digest (ZONEMD) resource record. that's the vibe check: it's a ZONEMD RR, and this package is the one holding its hand. 🫶

⭐ METHODS ⭐

okay so the methods you get are:

  • everything inherited from the base class, plus ✨
  • the type-specific methods defined right here in this package ✨
⚠️ real talk though: using undocumented package features or reaching directly into internal data structures is discouraged. the docs literally say it could result in program termination or other unpredictable behaviour. not the cute kind of unpredictable. the crashing kind. 😭 so don't. 🙈

🎀 serial 🎀

        $serial = $rr->serial;
        $rr->serial( $serial );

this is an unsigned 32-bit integer — the zone serial number. she's a number, she's 32 bits, she's unsigned, she's the serial. periodt. 🔥

🎀 scheme 🎀

        $scheme = $rr->scheme;
        $rr->scheme( $scheme );

the scheme field is an 8-bit unsigned integer that says which methods are used to collate the data and present it as input to the hashing function. so basically: how do we feed this to the hash. iykyk. 🧚

🎀 algorithm 🎀

        $algorithm = $rr->algorithm;
        $rr->algorithm( $algorithm );

the algorithm field is an 8-bit unsigned integer that identifies the cryptographic hash algorithm used to construct the digest. 8 bits of "which hash are we doing". 👑

🎀 digest 🎀

        $digest = $rr->digest;
        $rr->digest( $digest );

the hexadecimal representation of the digest over the zone content. hex. pretty. iconic. ✨

🎀 digestbin 🎀

        $digestbin = $rr->digestbin;
        $rr->digestbin( $digestbin );

same digest, except binary representation of it, over the zone content. two representations, one digest, no cap. 💜
