1. Brutus |
Brutus is one of the most popular remote online password cracking tools. It claims to be the fastest and most flexible password cracking tool. I would argue this, please see 11. This tool is free and is only available for Windows systems. It was released back in October 2000. |
It supports HTTP (Basic Authentication), HTTP (HTML Form/CGI), POP3, FTP, SMB, Telnet and other types such as IMAP, NNTP, NetBus, etc. You can also create your own authentication types. This tool also supports multi-stage authentication engines and is able to connect 60 simultaneous targets. It also has resume and load options. So, you can pause the attack process any time and then resume whenever you want to resume. |
This tool has not been updated for many years. Still, it can be useful for you. |
2. RainbowCrack |
RainbowCrack is a hash cracker tool that uses a large-scale time-memory trade off process for faster password cracking than traditional brute force tools. Time-memory trade off is a computational process in which all plain text and hash pairs are calculated by using a selected hash algorithm. After computation, results are stored in the rainbow table. This process is very time consuming. But, once the table is ready, it can crack a password must faster than brute force tools. |
You also do not need to generate rainbow tablets by yourselves. Developers of RainbowCrack have also generated LM rainbow tables, NTLM rainbow tables, MD5 rainbow tables and Sha1 rainbow tables. Like RainbowCrack, these tables are also available for free. You can download these tables and use for your password cracking processes. |

This tool is available for both Windows and Linux systems. |

3. Wfuzz |
Wfuzz is another web application password cracking tool that tries to crack passwords with brute forcing. It can also be used to find hidden resources like directories, servlets and scripts. This tool can also identify different kind of injections including SQL Injection, XSS Injection, LDAP Injection, etc in Web applications. |
Key features of Wfuzz password cracking tool: |
Capability of injection via multiple points with multiple dictionary |
Output in colored HTML |
Post, headers and authentication data brute forcing |
Proxy and SOCK Support, Multiple Proxy Support |
Multi Threading |
Brute force HTTP Password |
POST and GET Brute forcing |
Time delay between requests |
Cookies fuzzing |
4. Cain and Abel |
Cain and Abel is a well-known password cracking tool that is capable of handling a variety of tasks. The most notable thing is that the tool is only available for Windows platforms. It can work as sniffer in the network, cracking encrypted passwords using the dictionary attack, recording VoIP conversations, brute force attacks, cryptanalysis attacks, revealing password boxes, uncovering cached passwords, decoding scrambled passwords, and analyzing routing protocols. |
Cain and Abel does not exploit any vulnerability or bugs. It only covers security weakness of protocols to grab the password. This tool was developed for network administrators, security professionals, forensics staff, and penetration testers. |

5. John the Ripper |
John the Ripper is another well-known free open source password cracking tool for Linux, Unix and Mac OS X. A Windows version is also available. This tool can detect weak passwords. A pro version of the tool is also available, which offers better features and native packages for target operating systems. You can also download Openwall GNU/*/Linux that comes with John the Ripper. |

6. THC Hydra |
THC Hydra is a fast network logon password cracking tool. When it is compared with other similar tools, it shows why it is faster. New modules are easy to install in the tool. You can easily add modules and enhance the features. It is available for Windows, Linux, Free BSD, Solaris and OS X. This tool supports various network protocols. Currently it supports Asterisk, AFP, Cisco AAA, Cisco auth, Cisco enable, CVS, Firebird, FTP, HTTP-FORM-GET, HTTP-FORM-POST, HTTP-GET, HTTP-HEAD, HTTP-PROXY, HTTPS-FORM-GET, HTTPS-FORM-POST, HTTPS-GET, HTTPS-HEAD, HTTP-Proxy, ICQ, IMAP, IRC, LDAP, MS-SQL, MYSQL, NCP, NNTP, Oracle Listener, Oracle SID, Oracle, PC-Anywhere, PCNFS, POP3, POSTGRES, RDP, Rexec, Rlogin, Rsh, SAP/R3, SIP, SMB, SMTP, SMTP Enum, SNMP, SOCKS5, SSH (v1 and v2), Subversion, Teamspeak (TS2), Telnet, VMware-Auth, VNC and XMPP. |

7. Medusa |
Medusa is also a password cracking tool similar to THC Hydra. It claims to be a speedy parallel, modular and login brute forcing tool. It supports HTTP, FTP, CVS, AFP, IMAP, MS SQL, MYSQL, NCP, NNTP, POP3, PostgreSQL, pcAnywhere, rlogin, SMB, rsh, SMTP, SNMP, SSH, SVN, VNC, VmAuthd and Telnet. While cracking the password, host, username and password can be flexible input while performing the attack. |
Medusa is a command line tool, so you need to learn commands before using the tool. Efficiency of the tool depends on network connectivity. On a local system, it can test 2000 passwords per minute. |
With this tool, you can also perform a parallel attack. Suppose you want to crack passwords of a few email accounts simultaneously. You can specify the username list. |

8. OphCrack |
OphCrack is a free rainbow-table based password cracking tool for Windows. It is the most popular Windows password cracking tool, but can also be used on Linux and Mac systems. It cracks LM and NTLM hashes. For cracking Windows XP, Vista and Windows 7, free rainbow-tables are also available. |
A live CD of OphCrack is also available to simplify the cracking. One can use the Live CD of OphCrack to crack Windows-based passwords. This tool is available for free. |

9. L0phtCrack |
L0phtCrack is an alternative to OphCrack. It attempts to crack Windows password from hashes. For cracking passwords, it uses Windows workstations, network servers, primary domain controllers, and Active Directory. It also uses dictionary and brute force attacking for generating and guessing passwords. It was acquired by Symantec and discontinued in 2006. Later L0pht developers again re-acquired it and launched L0phtCrack in 2009. |
It also comes with a schedule routine audit feature. One can set daily, weekly or monthly audits, and it will start scanning on the scheduled time. |
