How to Decrypt RAR Files without Password

RAR is an abbreviation for Roshal Archive. It is a file format developed by Eugene Roshal, a Russian software engineer. This archive file format provides computer users with a quick way to compress and secure files. Users can add a password while compressing files to ensure only intended users access the files. Unfortunately, this security feature is difficult to surmount when the user forgets the password. This can be quite inconvenient.

To make matters worse, WinRAR, the GUI-based version for Windows, uses a 256 bit AES encryption, which is hard to crack. So how do you decrypt a RAR file? Below are four methods that show you how to decrypt RAR files without password.

Method 1. Guess RAR Password with the Frequently-Used Password

This method is a no-brainer. If you can’t open the password-protected RAR file, begin by entering all the passwords you can remember. More often than not, the password is one of your most frequently used passwords. Follow the steps below:

Step 1: Double-click the RAR file and click the Extract to tab.

Step 2: Select the folder where you want to extract the contents. Windows will show you a prompt to enter a password. Enter the most likely password and click OK.

Step 3: Repeat step two and try all your frequently used passwords.

Step 4: If you still can’t decrypt WinRAR password protected files, move on to the next method below.
