About PEM Inspector

PEM Inspector is a Chrome extension that parses and visualizes PEM-formatted data—including both X.509 certificates and Certificate Signing Requests (CSR)—directly from web pages. It provides an intuitive interface for viewing detailed certificate information, making it easier for developers and security professionals to inspect and analyze certificate data.
