Password cracking process involves recovering a password from storage locations or from data, transmitted by a computer system on network. Password cracking term refers to group of techniques used to get password from a data system.
Hydra 4.2 For Mac Torrent Crack Free Download. Hydra 4.2 For Mac is a powerful image processor that offers you the possibility to combine a series of regular photos in order to create high dynamic range (HDR) images. Hydra Camera for Windows 10 Free Hydra Camera is a free and good point and shoot camera that comes with some extra features, special effects and editing tools. Hydra is a simple Mac app that enables you to recreate the effect by superimposing multiple images taken with the same scenery. Straightforward image processor that can combine up to 7 different images.
Purpose and reason of password cracking includes gaining an unauthorized access to a computer system or it can be recovery of forgotten password. There might be another reason of using password cracking technique that is for testing password strength so hacker could not hack into system.
Password cracking is normally performed thought repetitive process in which computer applies different combinations of password till the exact match.
Brute Force Password Cracking: Term brute force password cracking may also be referred as brute force attack. Brute force password cracking is respective process of guessing password, in this process software or tool creates a large number of password combinations. Basically it’s a trail-and-error technique used by software to obtain password information from system.
A brute force attack are normally used by hackers when there is no chance of taking advantage of encrypted system weakness or by security analysis experts to test an organization’s network security .This method of password cracking is very fast for short length passwords but for long length passwords dictionary attack technique is normally used.
Time taken by brute force password cracking software to crack password is normally depend upon speed of system and internet connection.
GPU Password Cracking:GPU is graphics processing unit, sometimes also called visual processing unit. Before talking about GPU password cracking we must have some understanding about hashes. When user enter password the password information stored in form of computer hashes using the one-way hashing algorithm.
In this password cracking technique using GPU software take a password guess and look through hashing algorithm and compare it or match it with the existing hashes till the exact match.
GPU can perform mathematical functions in parallel as GPU have hundreds of core that gives massive advantage in cracking password. GPU is much faster than CPU so that’s the reason of using GPU instead of CPU.
CUDA Password Cracking:CUDA Compute Unified Device Architecture is a model for programming and a platform that perform computations in parallel, created by NVIDIA for graphic processing.
CUDA Password cracking includes cracking passwords using Graphics card which have GPU chip, GPU can perform mathematical functions in parallel so the speed of cracking password is faster than CPU.GPU have many 32bit chips on it that perform this operation very quickly.
We can easily access CUDA through libraries, directives and with the help of different programming languages that includes C, C++ and FORTRAN.

A simple detail about password cracking tools from the wiki. In cryptanalysis and computer security, password cracking is the process of recovering passwords from data that have been stored in or transmitted by a computer system. A standard approach (brute-force attack) is to try guesses repeatedly for the password and check them against an available cryptographic hash of the password. Password cracker is not hacking a password; this software only recovers your password. Got it? So don’t use against someone’s system or illegally.
The other purposes of password cracking tools might be to help a user recover a forgotten password of a system or any software. But in the world of hacking, hackers are using such a tools to break or crack the stolen password hashes of a database. Or using them to hack the wireless network and crack the passwords. So hope you completely understand the primary purpose of password cracking tools.
List of Top 10 Password Cracking Tools:
- OphCrack
- RainbowCrack
- HashCat

2. RainbowCrack
The RainbowCrack password cracking tools is a general propose implementation of Philippe Oechslin’s faster time-memory trade-off technique. It cracks hashes with rainbow tables. RainbowCrack uses time-memory tradeoff algorithm to crack hashes. It differs from brute force hash crackers.
A brute force hash cracker generates all possible plaintexts and compute the corresponding hashes on the fly, then compare the hashes with the hash to be cracked. Once a match is found, the plaintext is found. If all possible plaintexts are tested, and no match is found, the plaintext is not found. With this type of hash cracking, all intermediate computation results are discarded.
Features:
- Full time-memory tradeoff tool suites, including rainbow table generation, sort, conversion and lookup
- Support rainbow table of any hash algorithm
- Support rainbow table of any charset
- Support rainbow table in raw file format (.rt) and compact file format (.rtc)
- Computation on multi-core processor support
- GPU acceleration with NVIDIA GPUs (CUDA technology)
- GPU acceleration with AMD GPUs (OpenCL technology)
- GPU acceleration with multiple GPUs
- Runs on Windows operating systems
- Windows XP 32-bit / 64-bit
- Windows Vista 32-bit / 64-bit
- Windows 7 32-bit / 64-bit
- Windows 8 32-bit / 64-bit
- Runs on Linux operating systems (x86 and x86_64)
- Unified rainbow table file format on all supported operating systems
- Command line user interface
- Graphics user interface

It 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.
It also helps you for recovering wireless network keys, revealing password boxes, uncovering cached passwords and analysing routing protocols. The program does not exploit any software vulnerabilities or bugs that could not be fixed with little effort. It covers some security aspects/weakness present in protocol’s standards, authentication methods and caching mechanisms; its main purpose is the simplified recovery of passwords and credentials from various sources. However, it also ships some “non-standard” utilities for Microsoft Windows users.
