cred_scanner is a command line tool designed to identify AWS credentials within files across local directories and subdirectories. The tool performs recursive scanning to detect potential access keys and generates reports on files that cannot be scanned due to format limitations. Built specifically for integration with CI/CD systems like Jenkins, the scanner can automatically fail builds when potential credentials are discovered. This functionality helps prevent accidental exposure of sensitive AWS access keys in source code repositories and build artifacts. The tool operates by examining file contents for patterns that match AWS credential formats, providing a security checkpoint in development workflows. It outputs a list of files containing potential credentials and identifies files that could not be processed during the scan. Written in Python 3.6, the scanner is designed for simplicity and effectiveness in automated security testing environments. The tool focuses on AWS-specific credential detection rather than general secret scanning.
