Bitcoin Address Generator

This script generates a P2PKH Bitcoin address with a specified prefix. It uses openssl for generating private keys, and Python libraries (ecdsa, pycryptodome, progressbar2) for cryptographic operations and displaying a progress bar.

Prerequisites

• openssl (to generate private keys)
• base58 (to encode keys in base58 format)
• Python 3
• Python packages: ecdsa, pycryptodome, progressbar2

Install openssl and base58

sudo apt-get install openssl base58

Install Python Packages

The script automatically checks for and installs the required Python packages. You can also manually install them using:

pip install ecdsa pycryptodome progressbar2

Usage

Clone the repository and run the script:

git clone https://github.com/zarei-dev/bitcoin_address_generator
cd bitcoin_address_generator
chmod +x generate_address.sh
./generate_address.sh <prefix>

Replace <prefix> with the desired prefix for the Bitcoin address.

Script Explanation

1. Private Key Generation: Uses openssl to generate a random 256-bit (32-byte) private key.
2. WIF Conversion: Converts the private key to Wallet Import Format (WIF) by adding a prefix, computing a checksum, and encoding it in base58.
3. Public Key Generation: Uses Python and the ecdsa library to derive the public key from the private key.
4. Address Generation: Uses Python with pycryptodome to compute the RIPEMD-160 hash, compute the SHA-256 hash, add the network byte, compute the checksum, and encode the result in base58 to produce the Bitcoin address.
5. Prefix Matching Loop with Progress Bar: Continuously generates keys, updates the progress bar, and checks if the address starts with the specified prefix. If it finds a match, it stops the progress bar and outputs the relevant keys.
6. Package Installation: Checks if the required Python packages are installed and installs them if necessary, suppressing the verbose output to keep it clean.

Example

./generate_address.sh a
