Creating a Password-Protected ZIP File

To demonstrate how to unlock a password-protected ZIP file, we first need to create one. Follow these steps:

  1. Create a text file called “secretinfo.txt” using the command:
sudo touch secretinfo.txt
  1. Now, generate a password-protected ZIP file named “” with the password “12345678” using this command:
sudo zip --password 12345678 secretinfo.txt

You can verify the existence of the ZIP file using the ‘ls’ command.

Cracking the Password with a Dictionary

Fcrackzip offers two methods for password cracking: brute force and dictionary-based attacks. Additionally, in this section, we’ll focus on the dictionary-based approach, which is more efficient. Follow these steps:

  1. Utilize fcrackzip with the following command:
sudo fcrackzip -D -p /home/frost/rockyou.txt -u

Here is the breakdown of what each part of the command does: Firstly,…

  • -D specifies that you are using a dictionary or wordlist.
  • -p indicates the password file.
  • /home/frost/rockyou.txt points to the location of your dictionary file (in this example, “rockyou.txt”).
  • -u signifies the use of unzip.
  • “” is the target password-protected ZIP file.

Once you’ve configured the command, press “Enter” to initiate the password cracking process.


In the conclusion It’s important to note that the strength of a password greatly influences the time required to crack it. Complex passphrases with special symbols are more secure and can take a considerable amount of time to decipher, even when using efficient tools like fcrackzip.

In most cases, cracking weak passwords will only take a few minutes with the help of fcrackzip or similar tools. To enhance your security, always opt for strong and unique passwords when encrypting your files.
