Is there anything on #cpan for creating a “visual representation” of a string, something like how randomart for ssh-keygen works? @Perl #askFedi

What is randomart produced by ssh-keygen?

When you generate a key, you get "randomart" from newer versions of OpenSSH. I am unable to find an explanation of why, and what I'm supposed to use it for. Generating public/private rsa key pair....

All I could find was some decade-old code by Robert Krimen that looks like a port of the relevant #OpenSSH #C code to #Perl as part of a package to store secrets in YAML and JSON files: metacpan.org/release/ROKR/App-…

Here’s the corresponding OpenSSH `fingerprint_randomart` function: github.com/openssh/openssh-por…

@mjgardner Thanks I didn’t think to check for an ssh module itself. I was looking for anything, like I was thinkin maybe either finding a way to turn strings into emoji representations somehow or worst-case just use something like the fold command in the shell to just arrange the string into a square/grid

As for folding to a certain line length:
• metacpan.org/pod/Text::Fold
• metacpan.org/pod/Text::ANSI::F…

Text::Fold

Turn “unicode” and “byte” string text into lines of a given width, soft-hyphenating broken words
