Digest:...eBabble(3)

💖 NAME 💖

okay so this is the Digest::BubbleBabble(3) manual page, and its whole main-character thing is literally Create bubble-babble fingerprints. slay. ✨

🫧 SYNOPSIS 🫧

bestie, the vibe is two little snippets of code:

# Create a fingerprint of a simple string.
use Digest::BubbleBabble qw( bubblebabble );
my $fingerprint = bubblebabble( Digest => "Pineapple" );

# Create a fingerprint of a SHA-1 hash.
use Digest::SHA1 qw( sha1 );
$fingerprint = bubblebabble( Digest => sha1("hello") );

🦋 DESCRIPTION 🦋

Digest::BubbleBabble takes a message digest — often generated by either of the MD5 or SHA-1 message digest algorithms — and creates a fingerprint of that digest in “bubble babble” format. Bubble babble is a method of representing 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. no cap, that’s the whole charm. 🫶

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. The key (a DSA or RSA key) is converted into a textual form, digested using Digest::SHA1, and run through bubblebabble to create the key fingerprint. iconic behavior, honestly. 👑

🌸 USAGE 🌸

Digest::BubbleBabble conditionally exports one function called bubblebabble; to import the function you must choose to import it, like this:

use Digest::BubbleBabble qw( bubblebabble );

🎀 bubblebabble( Digest => $digest ) 🎀

Currently takes only one pair of arguments, the key of which must be Digest, the value of which is the actual message digest $digest. You should generate this message digest yourself using either Digest::MD5 of Digest::SHA1. bestie, that’s the whole argument situation — one pair, no extras. 💅

Returns the bubble babble form of the digest. periodt. ✨
