## What it is
mkp224o is a C command-line tool that generates vanity ed25519 onion service (Tor hidden service v3) addresses by brute-forcing keypairs matching a given prefix. It outputs key directories ready to be used directly by Tor.

## Use cases
- generate a custom tor onion v3 address with a chosen prefix
- create vanity .onion addresses for hidden services
- brute-force ed25519 keypairs matching a base32 pattern
- benchmark ed25519 key generation performance
- produce tor service key folders ready to drop into torrc

## When to choose
- you run a tor onion service and want a memorable or branded .onion address
- you need offline generation of ed25519 hidden service keys on a unix-like system
- you want a fast, optimized C implementation for vanity onion address mining

## When to avoid
- you need vanity addresses for tor v2 (RSA) services or non-tor cryptocurrencies
- you are on a platform without libsodium and a C99 compiler
- you need addresses containing digits 0, 1, 8, or 9, which base32 encoding excludes
