Beleth

Beleth is a multi-threaded asynchronous SSH password auditing tool written in C. There are plenty of other password cracking programs out there that can do the job, but I wanted something small, fast, and custom as a proof of concept. After preliminary tests, Beleth was able to outperform both THC-Hydra and Ncrack. Beleth also allows you to run a remote command after successfully cracking a password. Pull requests are welcome as the development is an ongoing process. For a more in depth look at the code, check out Chokepoint development blog.

Disclaimer

Beleth is a password auditing tool and should not be run against anyone else's system without receiving proper permission first. By using this application on a live connection, you do so at your own risk.
