STAyzer is a Python-based command-line tool that audits SSH trust relationships across Linux systems by analyzing users' authorized_keys files. It discovers who can access each machine, detects shared SSH keys, identifies potentially risky trust relationships, and generates detailed reports in both human-readable and machine-readable formats.
Designed for Linux administrators, DevOps engineers, and security professionals, STAyzer makes it easy to audit SSH trust across dozens or hundreds of servers.
