Hi,

In this post we will see how we can crack password protected Zip file by using John The Ripper.

So lets start. First lets create a password protected .zip file using following command(fig-2.0):

$ zip — — password [password] [file_name.zip] [your file]

Now we have password protected zip file so lets assume we don’t know the password of that file so lets crack the password of the zip file.

First of all we need a tool called John The Ripper. In Kali its comes pre-installed but if you using any other linux distro you can simply install it by following command:-

$ sudo apt install john

After installation you can use it by simply typing following command(fig 3.0):

$ John -h
