🗝️ Random Private Key Generator

This is a web application that allows users to generate random private keys and corresponding public addresses for Bitcoin and Ethereum. Users can also view their balances (for Ethereum, it queries real-time balances using the Ethereum blockchain). The application uses BitcoinJS, Ethers.js, and Elliptic libraries for cryptographic key generation.

🚀 Features

  • Bitcoin and Ethereum Key Generation:

    • Easily generate random private keys for Bitcoin and Ethereum.
    • Bitcoin private keys can be viewed in WIF (Wallet Import Format) or hexadecimal.
    • Ethereum private keys are displayed in hexadecimal.

  • Public Key Formats for Bitcoin:

    • Supports both P2PKH (Pay-to-PubKey-Hash) and P2WPKH (Pay-to-Witness-PubKey-Hash) formats for Bitcoin public addresses.

  • Balance Check for Ethereum:

    • Queries real-time Ethereum balances using the Infura API.
    • Displays the balance in ETH for Ethereum addresses.

  • Dynamic UI:

    • Toggle between Bitcoin and Ethereum key generation.
    • Choose between different public key and private key formats for Bitcoin.

🛠️ Built With

  • Next.js - React framework for server-side rendering and static site generation.
  • BitcoinJS - JavaScript library for Bitcoin cryptography and transactions.
  • Ethers.js - Library for interacting with the Ethereum blockchain.
  • Elliptic - Elliptic curve cryptography library (secp256k1 for Bitcoin and Ethereum).

📦 Installation

To set up this project locally, follow these steps:

  1. Clone the repository:
git clone https://github.com/gkfyr/random-pvk-generator.git
  1. Navigate to the project folder:
cd random-pvk-generator
  1. Install the dependencies:
npm install
  1. Set up the .env file with your Infura API endpoint:
NEXT_PUBLIC_INFURA_ENDPOINT=<YOUR_INFURA_ENDPOINT>

Replace <YOUR_INFURA_ENDPOINT> with your Infura Project ID.

  1. Run the development server:
npm run dev

Open http://localhost:3000 to view the app in the browser.

📋 Usage

  1. Select either Bitcoin or Ethereum using the toggle buttons.
  2. For Bitcoin, you can choose the type of public key (P2PKH or P2WPKH) and private key format (WIF or Hexadecimal).
  3. Click the Reload button to generate 8 new keys and addresses.
  4. If Ethereum is selected, balances for the generated addresses will be fetched automatically.
