crowbar

Crowbar, a brute forcing tool designed for penetration testing, uniquely enables the use of SSH keys for authentication instead of traditional username and password combinations, enhancing the effectiveness of attacks on various protocols. It supports OpenVPN, RDP with NLA, SSH private key authentication, and VNC key authentication, making it versatile for targeting different services. Notable features include the ability to scan target ports, utilize static or list-based passwords, and log successful attempts, all while supporting multi-threading for efficient operations.
