💖 Net::DNS::RR::SSHFP 💖

okay so this is the manual page for Net::DNS::RR::SSHFP, living in section 3 of the User Contributed Perl Documentation, and bestie it is literally the DNS SSH Fingerprint (SSHFP) resource record module. Buckle up, it's cute and it's short and we're gonna slay it 🫶

✨ NAME ✨

Net::DNS::RR::SSHFP — DNS SSHFP resource record. that's it, that's the vibe 💅

🌸 SYNOPSIS 🌸

        use Net::DNS;
        $rr = Net::DNS::RR->new('name SSHFP algorithm fptype fp');

look at that. iconic. you just use Net::DNS; and then build the record with that one new call, no cap 🎀

🦋 DESCRIPTION 🦋

DNS SSH Fingerprint (SSHFP) resource records. yes babe, that's the whole description, we love a concise queen 👑

⭐ METHODS ⭐

The available methods are those inherited from the base class augmented by the type-specific methods defined in this package.

⚠️ real talk: use of undocumented package features or direct access to internal data structures is discouraged and could result in program termination or other unpredictable behaviour. like… don't poke the internals, she bites 😭💀

🧚 algorithm

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

The 8-bit algorithm number describes the algorithm used to construct the public key. eight whole bits of "which crypto are we doing" energy ✨

🍓 fptype

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

The 8-bit fingerprint type number describes the message-digest algorithm used to calculate the fingerprint of the public key. so algorithm is the key algorithm, fptype is the digest algorithm — two different 8-bit numbers, don't mix them up bestie 💜

🎀 fingerprint, fp

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

Hexadecimal representation of the fingerprint digest. hex girlies rise 🌈

🔥 fpbin

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

Returns opaque octet string representing the fingerprint digest. the raw bytes version, for when hex just isn't your main character 💅

🫶 babble

        print $rr->babble;

The babble() method returns the 'BabbleBubble' representation of the fingerprint if the Digest::BubbleBabble package is available, otherwise an empty string is returned. so like, no package = empty string, no error, no drama 🙈

Bubble babble represents a message digest as a string of "real" words, to make the fingerprint easier to remember. The "words" are not necessarily real words, but they look more like words than a string of hex characters. it's giving "hex but make it readable" ✨

Bubble babble fingerprinting is used by the SSH2 suite (and consequently by Net::SSH::Perl, the Perl SSH implementation) to display easy-to-remember key fingerprints. so yes, this is the thing your SSH client shows you and you go "huh, cute" 🔑

The 'BubbleBabble' string is appended as a comment when the string method is called. free little garnish, we love that 🎁
