OpenSSH 5.1 introduced a visual hash representation of public keys to help users easily recall and verify SSH host keys. This tool, 'ssh-artist,' allows users to create SSH keys with desired visual patterns by drawing the end state and running a command to generate keys matching that design.

Interesting, but is it safe? I mean, does the provided pattern also need to be kept secret to protect the secrecy and/or privacy of the generated key, or it does not matter?

“This feature presents a great opportunity to fight against truly random key generation in order to trade security for arbitrary human desires.” - Gotta love it, I’m laughing so hard right now. Great project :)

Great procrastination tool ! But would probably be a lot faster in another language (ASM, WAT, C, Rust, C++, Go, C#, Java, other), even if cryptographic implementation are made in C / C++.
