SmartGenCC.py

Overview

The SmartGenCC.py script is designed to generate valid (Luhn-compliant) credit card numbers based on BIN (Bank Identification Number) wildcard strings.

Features

• Outputs Luhn-compliant CC numbers (15 or 16 digits).
• Inputs a single BIN wildcard OR file with BIN wildcards.
• Adjustable batch size per output CSV (default is 100,000 CCs per CSV).

Usage

To run the script, use the following command format:

python3 CCs_from_BINs.py <bin_value_or_file> [--batch <batch_size>]

• <bin_value_or_file> (required):

  • The BIN value or the path to a file containing BIN values. The BIN value should contain asterisks (*) representing the variable digits.
  • Example: 372395********* (American Express: 15 digits total)
  • Example: 423456********** (other cards: 16 digits total)
  • Example: bin_values.txt (text file with multiple wildcard BINs)

• --batch, -b: (optional):

  • Maximum number of credit card numbers per CSV file (default is 100,000).

Examples

• Generate credit card numbers for a single BIN value with the default batch size:

  python CCs_from_BINs.py 423456**********
  

• Generate credit card numbers for multiple BIN values from a file with a specified batch size:

  python CCs_from_BINs.py bin_values.txt --batch 50000
