2.3. Decrypt Encrypted ZIP File Online

Asides from applications, you can also decrypt your encrypted ZIP file with an online tool. Online Hash Crack is the go-to online password hacker for the majority of people who use this option. However, while this method may seem convenient, it is not one that we fully recommend.

First, this online software doesn’t guarantee the safety of your file. Also, the software produces a list of password combinations that you have to try individually. Finally, you can’t use Online Hash Crack if you have a ZIP file that is larger than 200 MB.

We only recommend this method if the other two don’t work.

Step 1: Visit the Online Hash Crack website.
