crowbar - Brute forcing tool that can be used during penetration tests

Description

Crowbar (formally known as Levye) is a brute forcing tool that can be used during penetration tests. It was developed to brute force some protocols in a different manner according to other popular brute forcing tools. As an example, while most brute forcing tools use username and password for SSH brute force, Crowbar uses SSH key(s). This allows for any private keys that have been obtained during penetration tests, to be used to attack other SSH servers.

Currently Crowbar supports

OpenVPN (-b openvpn)
Remote Desktop Protocol (RDP) with NLA support (-b rdp)
SSH private key authentication (-b sshkey)
VNC key authentication (-b vpn)
