## What it is
Scallion is a GPU-accelerated (OpenCL) vanity key generator that creates custom .onion addresses for Tor hidden services and vanity GPG keys. It runs on Mono/.NET and brute-forces RSA key hashes on the GPU to find addresses matching a chosen prefix.

## Use cases
- generate a custom vanity .onion address for a tor hidden service
- create a vanity gpg key with a chosen prefix
- brute-force onion hashes using a gpu
- find tor v2 onion addresses starting with a specific word

## When to choose
- you specifically need a vanity Tor v2 onion address and have an OpenCL-capable GPU
- you want a GPU-accelerated vanity GPG key generator

## When to avoid
- you need Tor v3 onion addresses - the project does not support them and v2 addresses no longer work
- you need a maintained tool - the project is explicitly unmaintained and depends on deprecated OpenSSL versions
- you don't have an Nvidia GPU or an old OS/docker image to satisfy the OpenSSL dependency
