Ophcrack is a free Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a Graphical User Interface and runs on multiple platforms.Crowbar (formally known as Levye) is a brute forcing tool that can be used during penetration tests. It was developed to brute horse some protocols in a different manner according to other popular brute forcing tools. BruteSpray takes nmap GNMAP/XML output and automatically brute-forces services with default credentials using Medusa. BruteSpray can even find non-standard ports by using the -sV inside Nmap.DBPwAudit is a Java tool that allows you to perform online audits of password quality for several database engines. The application design allows for easy adding of additional database drivers by simply copying new JDBC drivers to the jdbc directory.hashcat is the world’s fastest and most advanced password recovery utility, supporting five unique modes of attack for over 200 highly-optimized hashing algorithms. hashcat currently supports CPUs, GPUs, and other hardware accelerators on Linux, Windows, and OSX, and has facilities to help enable distributed password cracking.HexorBase is a database application designed for administering and auditing multiple database servers simultaneously from a centralized location, it is capable of performing SQL queries and bruteforce attacks against common database servers (MySQL, SQLite, Microsoft SQL Server, Oracle, PostgreSQL ).
