Today passwords are used to control access to information, varying from personal identification numbers that we use for credit cards, automatic teller machines, telephone calling cards, and the voice mail systems to more complex alphanumeric passwords that are used to protect access towards different files, network servers, and computer systems.
Today we will share with you the best password cracking tools of 2021. Passwords are being used as they are simple, less expensive and very convenient to use and implement. In short, we can say that passwords are the most common form of authentication.
On the other hand, passwords are also seemed to be a poor form of protection. The CERT that stands for Computer Emergency Response Team has calculated that about 80% of the security accidents occur due to the selection of poor passwords.
It is difficult to handle problems related to passwords as a single computer system may have hundreds or even thousands of password-protected accounts and only one needs to be compromised to give access to the attacker to enter the local system or network. Today problems are much devastating on a big scale because of the interconnected internet, a professional hacker might just enter into our computer system causing no harm but using it as a platform to attack a population of millions of targets.

Different Types of Password Attacks
- The Dictionary Attack
A dictionary attack is an attack that is based on estimation guessing and uses a precompiled list of options. An option that is to work is tried only in this kind of attack and not all the options are gone forward with
Here the dictionary combinations are indeed based on possible values and not tend to consider options of remote possibility. It might be based on the knowledge of one or a few ley information about the target that includes names of family members or even birthdays. Moreover, a dictionary is based on the combinations that are observed around a massive number of users in order to determine the most commonly used patterns. The dictionary usually includes real words other than random strings of characters.
The attack time over here is reduced as the numbers of combinations are restricted only to ones on the list.
- The Brute Force attack
The brute force attack is an attack in which the hacker tries to get the password by trying out every possible combination of characters. Here the number of attempts gets restricted by maximum position and number of characters.
This takes a lot of time to complete but here there are more chances of coverage of likely clear text value ( all possibilities are seen when set to maximum length and every possible character is considered in every position). This is a combination lock that requires three numbers that are to be taken in a sequence and every possible combination needs to be tried on. For example first 1-2-3 and then 1-2-4
Such an attack may not use all the options in a sequenced manner. The advanced brute attack makes particular assumptions like complexity rules need uppercase, the first character must be upper than lower case.
