Nosey Parker is a command-line program designed to identify secrets and sensitive information within textual data and Git history. The tool scans repositories and files to detect various types of confidential data including API keys, passwords, tokens, and other sensitive credentials that may have been inadvertently committed to version control systems. It operates through pattern matching and signature-based detection to locate potentially exposed secrets across different file types and formats. The tool can analyze both current file contents and historical Git commits to identify sensitive data that may have been present in previous versions. Nosey Parker provides functionality for scanning local repositories, remote Git repositories, and individual files or directories. It generates reports detailing the location and type of sensitive information discovered during the scanning process. The tool supports various output formats and can be integrated into continuous integration pipelines to prevent sensitive data from being committed to repositories.
