This tool was designed for network administrators, penetration testing, security professionals and forensic personnel. Download Cain and Abel


3. Rainbowcrack

Project-rainbowcrack.com  differs from the brute force method, as it uses large pre-computed tables called rainbow tables to reduce the amount of time needed to decrypt a password.

I was able to unload the rainbow boards myself when I tried it. This tool is available for Windows and Linux operating systems.


4. John the Ripper

John the Ripper is well known and fast to decrypt passwords available for UNIX, Windows, DOS, BeOS, and OpenVMS.

Its main objective is to detect weak UNIX passwords. There is professional software that offers extraordinary versions and native packages for the different operating systems.


5. Wfuzz

Wfuzz was designed for brute force attacks. It can be used to search for unlinked resources (directories, servlets, script, etc).

Forms with parameters (user/password), Bruteforce get and post for the control of different types of injections (SQL, XSS, LDAP, etc.).


6. Aircrack Ng

Analyze the wireless encryption packets and then try to discover passwords through your cracking algorithm.

Implements the standard FMS attack along with some optimizations such as Korek and PTW attacks.

Thanks to this method in which the results are faster compared to other cracking tools such as WEP.

It is available for Windows and Linux operating systems and you can Download Aircrack ng now.


7. Tch Hydra

You can perform fast dictionary attacks against more than 3 protocols including Telnet, FTP, HTTP, HTTPS, SMB and much more.

Medusa is also a tool to decrypt passwords similar to THC Hydra.

Working with HTTP, FTP, CVS, IMAP, MS SQL, NCP, NNTP, POP3, Postgres SQL, PCAnywhere, login, SMB, RSH, SMTP, SMNP, SSH, SVH, VNC, VMAUTHD, and Telenet.

Medusa allows you to perform a parallel attack, for example, if you want to know passwords of a few email accounts, at the same time you can mention the list of user names, along with the list of passwords.


9. L0phtCrack

It uses Windows workstations, primary domain controllers, network servers, and Active Directory for password cracking. It also uses the dictionary and brute force method.

L0phtCrack is full of advanced features such as programming, hash extraction from Windows versions of 64 bits, multiprocessor algorithms, and network monitoring and decoding.


10. Ophcrack

This is based on a Windows-based rainbow table. It comes with a graphical user interface (GUI) and runs on multiple platforms.

It can also be used on Linux and Mac systems. It’s an excellent free tool for all hackers and you can Download OphCrack here

You can also download free and paid rainbow tables for ophcrack.
