keyFinder

KeyFinder is a browser extension designed for Chrome and Firefox that passively scans web pages for leaked API keys, tokens, and secrets. With over 80 detection patterns across multiple categories such as cloud services, payments, and databases, it operates silently in the background, leveraging techniques like entropy analysis and monitoring various attack surfaces to identify sensitive information. Notable features include zero dependencies, compatibility with modern web standards (Manifest V3), and the ability to alert users via tab badges when potential exposures are detected.
