Password security tools
acccheck (SMB password guessing and dictionary attack tool)
password discovery, password strength testing
The acccheck tool performs a password guessing and dictionary attack on SMB services used to share files and printers.
Crowbar (brute forcing tool)
While most brute forcing tools take a similar approach, Crowbar can use different methods that are not always available in other utilities. For example, Crowbar can use SSH keys, instead of the typical username and password combination. This might be useful during penetration testing when these type of details are discovered.
eapmd5pass (offline EAP-MD5 dictionary attack tool)
network analysis, password discovery, penetration testing
A tool like this would be most likely used to show the weakness of old authentication protocols, including penetration testing.

PassGen (password dictionary attack tool)
