Small python script to convert list of Bitcoin / Bitcoin Cash private keys into public addresses and check for current balance, total in and total out of that address.

Install requirements:

python 2.*

Usage:

git clone git@github.com:asimd/bitcoincheck.git
pip install pybitcointools
python btc.py

This tool uses Google BigQueryDB query results as input. That input comes from scanning regex expression for all public Github repos matching the Bitcoin private key.

BigQueryDB query:

#standardSQL
SELECT f.repo_name, f.path, c.pkey
FROM `bigquery-public-data.github_repos.files` f JOIN
     (SELECT id,
             REGEXP_EXTRACT(content, r'(?:^|[^a-zA-Z0=9])(5[HJK][123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ]{48,49})(?:$|[^a-zA-Z0-9])') AS pkey
      FROM `bigquery-public-data.github_repos.contents`
      WHERE REGEXP_CONTAINS(content, r'(?:^|[^a-zA-Z0=9])(5[HJK][123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ]{48,49})(?:$|[^a-zA-Z0-9])')
     ) c
     ON f.id = c.id;

After that, it uses Blockchain's public API for BTC and BitBox's public API for BCH to check the balances for the given address.
