gen-secp 0.1.5

Generate secp256k1 keypair CLI

gen-secp

gen-secp is a lightweight Python CLI and website for generating secp256k1 keypairs. It quickly prints fresh keys for local development, can emit detailed output, and offers a static WebAssembly-powered demo so you can generate keys directly in your browser.

• Web demo: https://gen-secp.github.io
• Source: https://github.com/tonidy/gen-secp

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Requirements:

• uv (https://docs.astral.sh/uv)

Installation

Install directly from PyPI (recommended):

uv tool install gen-secp

Or for development, clone and install locally:

git clone https://github.com/tonidy/gen-secp.git
cd gen-secp
uv tool install .

To update after pulling new changes:

uv tool update

For PEM export support, install with coincurve extra:

uv sync --extra coincurve

Usage

The project provides a CLI entry. Example commands:

uv run genkey

Runs the command to generate a new key or secure artifact and prints or saves the result depending on configuration.

uv run genkey --long

Prints the private key plus compressed and uncompressed public keys.

uv run genkey --save mykey

Writes mykey.priv.hex (private key hex string) and mykey.pub.txt with both public key encodings in the current directory.

Run uv run genkey -h for the full list of options.

uv run genkey --coincurve --save mykey

Uses the original coincurve implementation (requires the extra above) and writes SEC1 PEM files (mykey.pem, mykey.pub.pem).

Browser demo

The static site under docs/ is deployed to GitHub Pages. It bundles the same Python implementation (executed through Pyodide WebAssembly) to generate keypairs client-side. Open https://tonidy.github.io/gen-secp and click “Generate Keypair”.

Troubleshooting

• If you see "python: command not found", ensure Python is installed and on your PATH.
• If dependencies fail to install, try uv sync again.
