Bitcoin Private Key Scanner Github Repack

If you want to experiment for learning:

These scanners are not inherently illegal. Developers create them for:

However, the celebrity status of these tools comes from the hypothetical "lottery" scenario: finding an address with a non-zero balance.

Even if a scanner works perfectly:

In practice, scanners find keys only in:

You will NOT find "lost" Satoshi-era wallets with a random scanner – it's mathematically impossible.

Before you run any crypto-related tool from GitHub, perform this checklist: bitcoin private key scanner github repack

import ecdsa
import hashlib
import base58
def private_key_to_address(private_key_hex):
# Convert hex to bytes
private_key_bytes = bytes.fromhex(private_key_hex)
# Generate public key
sk = ecdsa.SigningKey.from_string(private_key_bytes, curve=ecdsa.SECP256k1)
vk = sk.get_verifying_key()
public_key = b'\x04' + vk.to_string()
# SHA-256 then RIPEMD-160
sha256_b = hashlib.sha256(public_key).digest()
ripemd160 = hashlib.new('ripemd160')
ripemd160.update(sha256_b)
public_key_hash = ripemd160.digest()
# Add version byte (0x00 for mainnet) and checksum
versioned_payload = b'\x00' + public_key_hash
checksum = hashlib.sha256(hashlib.sha256(versioned_payload).digest()).digest()[:4]
address_bytes = versioned_payload + checksum
return base58.b58encode(address_bytes).decode('utf-8')

For API queries, they often use:

A Bitcoin private key scanner is a tool that generates or loads private keys, derives the corresponding public address, and checks if that address has a non-zero balance on the blockchain.

Repack usually means someone has taken an existing open-source scanner, bundled it with dependencies, maybe added a GUI or batch scripts, and redistributed it.

git clone https://github.com/ryancdotorg/brainflayer
cd brainflayer
make
# Download a list of funded addresses (e.g., from https://addresses.loyce.club/)
# Then scan for brain wallets from a wordlist
./brainflayer -v -b funded_addresses.txt -f rockyou.txt

For a simple Python scanner (non-random, just checks a list): If you want to experiment for learning: These

import requests
addresses = ["1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa"]  # Genesis address
for addr in addresses:
    resp = requests.get(f"https://blockchain.info/q/addressbalance/addr")
    print(f"addr: int(resp.text)/1e8 BTC")

GitHub is the world’s largest source code repository. You will find dozens of public repositories with names like btc-scanner, hound, brainflayer, or private-key-generator. Some are legitimate academic or security research tools. For example:

These are not scams in themselves; they are cryptographic tools. The problem arises from how they are repackaged and marketed to non-technical users.
