Password Hash Cracker

Echo “c7e86705ea4642f5b8a6e5” hash.txt The simplest password cracking method that will crack basic passwords is with john or hashcat using the rockyou.txt word list This is. Password Cracker is a desktop tool that will let you view hidden passwords in Windows applications. Some applications hide passwords by asterisks for security purposes when creating an account. Using the tool, you don’t have to note down the passwords on a piece of paper. If you want to obtain a lost Windows password, you have to extract the NTLM password hashes from the SAM (Security Account Manager) file and use password hacking tool to crack them. LCP is one of the most effective password auditing and recovery tools that can crack Windows password using a dictionary attack, brute force attack, or a hybrid attack.

About Md4 :

Md4 (Message Digest 4) is a cryptographic hash function created by Ronald Rivest in 1990. This algorithm takes as input a string and makes a hash from it. This hash is 128 bits, 32 caracters long. Because of security problems, Md4 was abandoned for its little brother, Md5. The reason for that is that one can easily attack Md4 with collisions, in a few milliseconds. The Md5 is more secure, because you need 2^64 operations (anniversary attack) to make a collision (even though Md5 is not secure enough). Microsoft's NTLM hash use Md4 with few differences. You shouldn't use Md4 as a cryptographic function to store critical data, since it's very easy to decrypt. This website allows you to decrypt your md4 hashes

CrackStation uses massive pre-computed lookup tables to crack password hashes. These tables store a mapping between the hash of a password, and the correct password for that hash. The hash values are indexed so that it is possible to quickly search the database for a given hash. In the simplest model, the password cracker may begin by trying 00000000. Then it may try 00000001, 00000010, 00000100, and so on and so forth until it has tried every possible combination of. This challenge is all about cracking password hashes. The two most popular tools for doing this kind of work are Hashcat and John the Ripper. The first thing to do before you try and crack a hash is to attempt to identify what type it is - and I say “ attempt ” because sometimes it can be a bit of a challenge, as we’ll see in a bit. As we know in the brute force attacks, hash cracker produces all the possible combinations in the plain text format and computes and compares with the password hash it cracks and once it finds the match of the password, it’s all done but if it doesn’t find the perfect match of the plain text then all the cracked hashes result are discarded.

if you're lucky of course. Our online database contains more than 1.000.000.000 Md4 hash, coming from all the wordlist I was able to find on the internet. I then computed for days to enlarge it and to make it relevant and unique, in order to help you decrypt your Md4 hashes.
You shouldn't use Md4 to store your passwords, you would better be using Sha-2 functions, and use a salt, which is a little (or not) string that you add to your user's password to make it way more difficult to bruteforce or to find using rainbow tables such as this website.

Brute force password cracker and breaking tools are sometimes necessary when you lose your password. There are other cases as well, such as white hat penetration testing or possibly testing the strength of your own passwords.

Password crackers that can brute force passwords by trying a large amount of queries pulled from a .txt or .csv file are available across all operating systems.

Windows Brute Force Password Cracker’s

If you are not a native Linux or Unix user you may wish to brute force passwords on your windows operating system.

Brutus

Download Brutus

Are you are looking for lightning fast and windows only password cracking software? Brutus is you answer.

Brutus uses a technique called time memory trade off which allows for large multi-threaded brute forcing attacks all at once.

Brutus like Ophcrack requires you to use rainbow tables for brute force password cracking. You can go a few routes to obtain rainbow tables.

Rainbow tables can be generated yourself and collected over time.
Free sets of rainbow tables can also be grabbed here: http://project-rainbowcrack.com/table.htm
As a last resort or for a bit more data rainbow tables are available for purchase at http://www.osforensics.com/rainbowtables_hashsets.html and http://project-rainbowcrack.com/buy.php

Cain and Able

Download Cain and Able

Cain and Able is not only a password cracker but and overall excellent network security tool.

Oxid.it the creators of Cain and Able detail the software as,

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.

As you can see Cain and Able opens up many more options and methods for obtaining passwords to crack and brute forcing them.

Linux Password Cracking Software

Linux is widely known as a common OS for security professionals and students. Linux has the most brute force password cracking software available compared to any OS and will give you endless options.

John the Ripper

Download John the Ripper

John the Ripper is compatible with Linux, Unix and fully able to brute force Windows LM hashes. Although, John the Ripper is not directly suited to Windows. This software is extremely fast at brute force cracking Linux and Unix NTLM hashes.

John the Ripper Pro is also available for business facing users that would like the software tailored to their operating system. The free JtR will work very well for the average user.

John the Ripper is a registered project with Open Hub and it is listed at SecTools.

Medusa

Download Medusa

Medusa is a variation of the THC Hydra cracking software. Medusa has many advantages by being a speedy parallel, modular and login brute forcing tool.

Medusa speed really brings a great amount of appeal to the password cracking suite but the best feature of Medusa is their ability to run across a wide array of platforms and services.

Medusa supports:

HTTP
FTP
SSH
AFP
IMAP
MS SQL
MYSQL
NCP
NNTP
POP3
