Net::DNS::SEC(3)

💖 NAME 💖

okay bestie, this is Net::DNS::SEC(3) — a User Contributed Perl Documentation page for the DNSSEC extensions to Net::DNS. yes, we're doing crypto DNS stuff and it's lowkey iconic. 🦋

✨ SYNOPSIS ✨

        use Net::DNS::SEC;

🌸 DESCRIPTION 🌸

So Net::DNS::SEC is installed as an extension to an existing Net::DNS installation, providing packages to support DNSSEC as specified in RFC4033, RFC4034, RFC4035 and related documents. 💅

It also provides support for SIG0, which is useful for dynamic updates. not me being useful for dynamic updates 😭

It implements cryptographic signature generation and verification functions using RSA, DSA, ECDSA, and Edwards curve algorithms. 🔥

And the extended features are made available by replacing Net::DNS by Net::DNS::SEC in the use declaration. that's the whole slay: swap the name, get the extensions. ✨

🧰 UTILITY FUNCTIONS 🧰

These are the little helper functions, bestie. no cap, they're here to convert things and diff keys. 🫶

🔢 algorithm

        $mnemonic = algorithm( 5 );
        $numeric  = algorithm( 'RSA-SHA1' );
        print "algorithm mnemonic\t", $mnemonic, "\n";
        print "algorithm number:\t",  $numeric,  "\n";

algorithm() provides conversions between an algorithm code number and the corresponding mnemonic. numeric in, mnemonic out; mnemonic in, numeric out. icon behavior. 💖

🧬 digtype

        $mnemonic = digtype( 2 );
        $numeric  = digtype( 'SHA-256' );
        print "digest type mnemonic\t", $mnemonic, "\n";
        print "digest type number:\t",  $numeric,  "\n";

digtype() provides conversions between a digest type number and the corresponding mnemonic. same energy as above, but for digest types. 🎀

🔑 key_difference

        @result = key_difference( \@a, \@b );

Fills @result with all keys in array @a that are not in array @b. it's giving "what's in @a but not @b" and honestly? useful. 💀
