Open Source Java Brute Force Tools

Ophcrack is a Windows password cracker based on a time-memory trade-off using rainbow tables. This is a new variant of Hellman's original trade-off, with better performance. It recovers 99.9% of alphanumeric passwords in seconds.

DirBuster is a multi threaded java application designed to brute force directories and files names on web/application servers.

This is a simple but sophisticated open source password recovery tool for M$ Windows, it can effectively 'crack' any password protected archive that can be decompressed by 7zip given enough time and resources. It can also bruteforce MD2, MD5, SHA-1 and SHA-2 hashes (SHA-256, SHA-384, SHA-512), CRC16, CRC32, CRC64 and Adler32 hashed passwords for both Windows, and Linux. It requires java 7u4 and above, and 7-zip v9.20 and up for archive recovery. Keeping these above applications up to date ensures peak performance. if you have any ideas, bugs, tips/improvements and/or suggestions please dont hesitate to contact me NB AS OF V1.07 PLEASE MAKE SURE 'resources' FOLDER IS IN THE SAME DIRECTORY AS THE JPasswordRecoveryTool.jar Known Bugs(v1.09): -although md2 was selceted by default for hash recovery if you did not slected another value and reselect md2 it would use md5 by default

Hash Cracker is an application developed in java swings that allows a user to crack MD2, MD5, SHA-1,SHA-256,SHA-384,SHA-512 hashes either using brute force or using wordlists of the user's choice based on the users choice.

Java implementation of Sudoku. Visually attractive, interactive version with intelligent and brute force solving strategies.

AESTextCrypt is an easy-to-use open source tool for text encryption and decryption. Primarily intended for use with email, use it wherever you need to protect text from prying eyes. The encrypted text can be copy/pasted into any text-handling application (e.g. email) instead of plain text. Convenience buttons are provided for clipboard operations. AESTextCrypt uses AES-256 bit encryption which is the strongest available encryption scheme. It also employs bcrypt, which implements key-stretching and an adaptive key setup phase, the complexity (number of rounds) of which is automatically set to match the processing power of the encrypting computer. This makes it highly resistant to dictionary attack. AESTextCrypt is written in Java, so can be run on all desktop platforms - Windows, Mac and Linux.

Generic clustering/load-balancing platform (over a LAN or internet) using java based P2P Aorta workers that execute java "tasklets". Various tasklets can be implemented to solve fractals, process images, render webpages, crack RSA "brute force".

CryptoHelper is a Java program designed to aid in the decryption of classical ciphers, ie pre WWII ciphers. It brings together tools like frequency analysis, friedman tests, enciphering/deciphering for several clasical ciphers, and brute force algorithm

HTTPBrute is used to calculate HTTP Digest Access Authentication as per RFC 2617. The tool will be able to perform brute force attacks to retrieve a lost password for a given Authentication response. MD5 is the only hashing algorithm implemented.

HumanSudokuSolver is intended to solve Sudoku puzzles in a way human beings would do (non brute force). It currently solves most of the puzzles I tried and can output a step-by-step solution. Developers who want to contribute are welcome!

JBrute is an open source tool written in Java to audit security and stronghold of stored password for several open source and commercial apps. It is focused to provide multi-platform support and flexible parameters to cover most of the possible password-auditing scenarios. Java Runtime version 1.7 or higher is required for running JBrute.

Java project. A java application that creates jars with encrypted content inside. With a selfextract and decrypt built in. GUI aswell as console functionallity. Options to include a key salt inside of the jar to hinder bruteforce attempts.

Password strength testing Java API utilizes Java platform independence and threading mechanisms. Provides a way to conduct custom brute force and dictionary stregth tests.

Java implementation of the most commonly used algorithms for exact string matching, where the pattern is given first.

JoinFinder is a useful tool that helps you to find join between two tables by foreign keys defined into tables or by a brute-force method. It is a Java8 project and it uses jna library for autocompletition feature. At the moment JoinFinder is in Italian and supports only MS SQL server, but I hope to add soon other DB support and English translation.

Balacing a chemical equation using the Laplace's rule to solve a system of linear equations or using the brute-force method. Khembalancer 2.5.5 received the "100% Free" award and that means Khembalancer does not contain any viruses, spyware, trojans and backdoors. For more information see: http://www.softpedia.com/progClean/Khembalancer-Clean-207422.html

Mjölnir is a a java-based brute force algorithm for obtaining keystore passwords by brute force. It is multi-threaded

Brute-force the input parameters of your numeric models when only the output is known.

Simple UI to test the effectiveness of a heuristic algorithm against the brute force method for path finding among an arbitrary number of arbitrarily placed points on a grid. This is an educational project, don't expect new and better methods.

This project provides a 'brute-force' search for optimum assembler fragments for Microchip Technology Inc's mid-range PIC processor range.

A java application for creating, playing and solving SuDoku puzzles of various types. Features both a Swing GUI and command-line operation. The automatic solving of puzzles uses "smart" techniques rather than a brute force search of every possibility.

This software uses a genetic algorithm to "evolve" reactor designs for Schema's space-simulation game, Star-Made (http://star-made.org/). One of the more unique aspects of the game is that ship power management is not as simple as filling a cube with power generation blocks. This mechanism leads to difficulties in getting maximal power generation out of such reactors. This program rectifies this issue by using a self-organizing variant of brute force search. Much of the search space is pruned early on by a user-selectable fitness function. Within a few epochs, reactor output quickly converges to several sub-optimal, yet high-output reactors. Given enough time, the idea is that the optimal reactor configuration will be yielded.

SNames is a threaded java dns scanner. It uses patterns to provide good bruteforce strength when trying to resolve hostnames.

Java based webapp that utilizes TCP Wrappers to grant an IP access to a ssh server. Brute force attacks can be avoided while still allowing password based ssh access from multiple, changing IP values.

This is a simple app, created around an original sudoku solver based only on heuristics, not brute force. It's coded in Java/SWT(GUI toolkit). It's an example of MVC and of Visitor, Observer, Strategy, Abstract Factory, Singleton Design Patterns.
