gen_btc_addr

Overview

gen_btc_addr.py is a Python script that generates Bitcoin private keys, public keys, and corresponding addresses in multiple formats including Base58, compressed, and Bech32. This tool also allows the creation of a QR code for easy sharing of the Bech32 address.

Features

• Generate Bitcoin private keys in hexadecimal, Wallet Import Format (WIF), and Base64.
• Generate public keys in uncompressed and compressed formats.
• Create Bitcoin addresses in Base58 (uncompressed and compressed) and Bech32 formats.
• Generate a QR code for the Bech32 address for easy sharing.

Usage

Command-Line Arguments

• -k <private_key>: Optionally specify a private key in hexadecimal format.

  Example:

  python3 gen_btc_addr.py -k d79c2d69c7eeaef52cfc7e2a35b5961ab77c4a0f637988a30436217007bd852a

If no private key is provided, a new one will be randomly generated using secure randomness from /dev/urandom.

Running the Script

Run the script from your command line:

python3 gen_btc_addr.py

Upon running the script, you will see the generated public and private key details, as well as a QR code image for the Bech32 address saved in the current directory.

Output

The script will generate:

Public Information

• Bitcoin Address (Uncompressed, Base58)
• Bitcoin Address (Compressed, Base58)
• Public Key (uncompressed Hex)
• Public Key (compressed Hex)
• Bech32 Address (QR code is generated for this address)

Private Information

• Private Key WIF (uncompressed)
• Private Key WIF (Compressed)
• Private Key (Hexadecimal)
• Private Key (Base64)

Dependencies

The script requires the following Python modules:

• ecdsa
• hashlib
• base58
• base64
• bech32
• qrcode
• Pillow (for QR code image generation)

You can install these dependencies using pip:

pip install ecdsa base58 bech32 qrcode[pil]
