## Project history and usage

mkp224o is cathugger's C program for generating vanity Tor onion service v3 addresses. Its name refers to Tor proposal 224, the proposal that introduced the v3 onion service design, and its README describes generation of vanity ed25519 onion addresses. The repository was created in 2017, is licensed under CC0-1.0, and depends on libsodium plus a C99 compiler and make/autoconf build tooling.

### Project history

In practice the user supplies one or more desired prefixes, and mkp224o repeatedly generates keys until it finds onion hostnames matching those filters. The README documents output directories containing secret and public keys and hostnames for discovered services, along with steps for copying the generated key material into a Tor hidden-service directory. It also notes base32 constraints on onion names, which makes some digits impossible in filters.

### How it is used

The tool's performance focus is a major part of its identity. Its optimization notes describe multiple ed25519 implementations selected at configure time, integer and binary-string filter representations, binary search for large filter lists, and batch mode for faster generation. Package managers such as Homebrew and Nix provide it as a niche security/privacy command-line tool; Homebrew records libsodium as its runtime dependency.
