cathugger/mkp224o — reverse-engineered prompt

Build me a fast terminal tool that can generate vanity Tor onion v3 service addresses. I want to give it one or more words or prefixes, like neko, and have it keep searching until it finds onion addresses that start with those filters.

It should create a separate folder for each found address, with the hostname and the Tor hidden service keys saved in the normal format so I can copy the folder into Tor later. Let me choose an output folder, load filters from a file, show useful progress and speed stats, and print a clear help screen.

Please make it validate filters early, especially because onion base32 addresses can’t use 0, 1, 8, or 9. It should be written as a portable C command line program for Unix like systems, build with configure and make, and use libsodium or the right ed25519 code. Include simple build and usage instructions, plus a Docker option if practical. Look up current Tor onion v3 docs online if needed.
