Please note that almost all online tools present a security threat especially if you want to unzip a file that contains important private data. When you upload your file over the Internet to their servers, you put your data at risk of being leaked out and hacked. Therefore, for data security, we don't recommend you to try online tools.

Another method to unzip an encrypted ZIP file when you have no password is the Command Prompt. With this method, you don't have to expose your private information to a security risk by using an online tool or even a downloadable tool.

To use the CMD line tool to unzip an encrypted ZIP file follow these steps:
To begin with, download the John the Ripper Zip file onto your computer and then extract it to your desktop and rename the folder as "John".
Step 1: Now open the "John" folder and then click to open the folder named "run" then create a new fold there and name it "Crack".
Step 2: Copy the password encrypted ZIP file that you want to crack and paste it in this new folder that you have named "Crack".
Step 3: Now, go back to your desktop then run the "Command Prompt" then key in the command "cd desktop/john/run" then click "Enter".
Step 4: Now, Create a password Harsh by typing in the command "zip2john.exe crack/YourFileName.zip>crack/key.txt" then click "Enter". Remember to insert the name of the file you want to crack in the above command in place of the phrase "YourFileName".
