GPU can perform mathematical functions in parallel as GPU have hundreds of core that gives massive advantage in cracking password. 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. When user enter password the password information stored in form of computer hashes using the one-way hashing algorithm. Before talking about GPU password cracking we must have some understanding about hashes. GPU is graphics processing unit, sometimes also called visual processing unit. Time taken by brute force password cracking software to crack password is normally depend upon speed of system and internet connection. This method of password cracking is very fast for short length passwords but for long length passwords dictionary attack technique is normally used. Basically it’s a trail-and-error technique used by software to obtain password information from system.Ī 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. Brute force password cracking is respective process of guessing password, in this process software or tool creates a large number of password combinations.

Term brute force password cracking may also be referred as brute force attack. Password cracking is normally performed thought repetitive process in which computer applies different combinations of password till the exact match. There might be another reason of using password cracking technique that is for testing password strength so hacker could not hack into system. Purpose and reason of password cracking includes gaining an unauthorized access to a computer system or it can be recovery of forgotten password. Password cracking term refers to group of techniques used to get password from a data system. Password cracking process involves recovering a password from storage locations or from data, transmitted by a computer system on network.
