Implementation for "Time-lock puzzles and timed-release Crypto" by Rivest, Shamir and Wagner.

Time Lock Puzzle Implementation

Getting Started

This repository is a Python implementation of the excellent paper Time-lock puzzles and timed-release Crypto by Shamir and Rivest.

Instructions:

1. Download 🐍 Python 3.7

2. Setup the environment. I recommend using virtualenvwrapper. Run : mkvirtualenv -p $(which python3) {YOUR_ENV_NAME}. Then workon {YOUR_ENV_NAME}.

3. Install packages/dependencies: pip install -r requirements.txt

4. Run the main function: python puzzle.py {SECONDS} {SQUARINGS_PER_SECOND} {REPEATS}. All three arguments are ints and all are required.

Production

🛑 DO NOT USE IN PRODUCTION ✋. This code is very experimental and is part of a bigger project which will be linked here soon. Security is not guaranteed, assume it is unsafe. In the meantime, feel free to play around. PRs are very welcome.
