You forgot the password of a RAR archive and you do not know how to find it? In this tutorial I will show you some quick and easy techniques that will help you recover the password of a RAR or ZIParchive.

Before you begin, you should know that the password can be found in the comments of your WinRAR file, especially if it is downloaded from the internet.

To check this, open your archive by double clicking the left mouse button.

Read the reviews, if you find a link, open it and look at the page, you need to find the password.Otherwise, try to crack the password for the archive with specialized software.

How's the password cracking?

There is a bunch of articles and videos on the Internet that explain how to find a Winrar password. What has always bothered in the content of these articles is lying.

Indeed, in many cases, the authors simply say for example "This is a 100% effective technique to find the password of your RAR archive" without saying that these methods prove ineffective if the password for the archive is complex.

In this part, I will mainly explain how the password cracking  to understand that there is not really a 100% effective technique to crack the password of a RAR file

You should know that all password cracking software uses in principle two methods:

  • The attack by Bruteforce: it  is to test all possible combinations of uppercase, lowercase letters, numbers and special characters.
  • The dictionary attack:  It is to  use a dictionary word, that is to say a file that contains many words. Indeed, most of the time users choose passwords with real meaning. (Love, 0000, QWERTY, password, dog's name, quotes, names of movies, etc ...).

 

So  to successfully crack a password, three factors are taken into account.

  • Your computer power calculation
  • The complexity of the password
  • The words containing the dictionary of the software used

So if the password you are looking for is more than 7 or 8 characters in length and contains special characters and numbers ... it may be impossible to break with your personal computer.

What you should remember is that the methods found on the Internet can be ineffective if the mixture of uppercase password, lowercase, numbers, punctuation marks and special characters.
