Free Hacking tools for Password Cracking
#26 John The Ripper
John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, and OpenVMS.
John, better known as John the Ripper, is a tool to find weak passwords of users in a server. John can map a dictionary or some search pattern as well as a password file to check for passwords. John supports different cracking modes and understands many ciphertext formats, like several DES variants, MD5 and blowfish. It can also be used to extract AFS and Windows NT passwords.
Documentation : https://www.openwall.com/john/doc/
According to official website Hashcat is the world’s fastest CPU-based password recovery tool.
While it’s not as fast as its GPU counterpart oclHashcat, large lists can be easily split in half with a good dictionary and a bit of knowledge of the command switches.
Hashcat was written somewhere in the middle of 2009. Yes, there were already close-to-perfect working tools supporting rule-based attacks like “PasswordsPro”, “John The Ripper”. However for some unknown reason, both of them did not support multi-threading. That was the only reason to write Hashcat: To make use of the multiple cores of modern CPUs.
Granted, that was not 100% correct. John the Ripper already supported MPI using a patch, but at that time it worked only for Brute-Force attack. There was no solution available to crack plain MD5 which supports MPI using rule-based attacks.

#28 Cain and Abel
Cain & Abel is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kind of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, recovering wireless network keys, revealing password boxes, uncovering cached passwords and analyzing routing protocols.
According to official website of thc-hydra, One of the biggest security holes are passwords, as every password security study shows. This tool is a proof of concept code, to give researchers and security consultants the possibility to show how easy it would be to gain unauthorized access from remote to a system and different online services
There are already several login hacking tools available, however the online services Either support more than one protocol to attack or support panellized Connects.
fcrackzip searches each zipfile given for encrypted files and tries to guess the password. All files must be encrypted with the same password, the more files you provide, the better.
Have you ever mis-typed a password for unzip? Unzip reacted pretty fast with ´incorrect password´, without decrypting the whole file. While the encryption algorithm used by zip is relatively secure, PK made cracking easy by providing hooks for very fast password-checking, directly in the zip file. Understanding these is crucial to zip password cracking.
