Project Structure

The project has been simplified to use vanilla JavaScript with ES modules:

key2pub/
├── index.js       # Main library functions
├── cli.js         # Command-line interface
├── index.html     # Web UI
├── script.js      # Web UI JavaScript
└── styles.css     # Web UI styling

Installation

npm install

Usage

Command Line

Run directly:

node cli.js <private-key>

Or install globally:

npm install -g .
key2pub <private-key>

Web Interface

Simply open the index.html file in any modern browser. No server is required as it uses ES modules to directly import the library functions.
