Linux create zip with password

How to Create a Password Protected ZIP File in Linux

ZIP is a very popular compression and file packaging utility for Unix-like operating systems as well as Windows. While perusing through the zip man page, I discovered some useful options for protecting zip archives.

In this post, I will show you how to create a password protected zip file on the terminal in Linux. This will help you learn a practical way of encrypting and decrypting contents of zip archive files.

First install zip utility in your Linux distribution using the package manger as shown.

How to Create Password Protected ZIP in Linux

Once installed, you can use the zip command with -p flag to create a password protected zip archive called ccat-command.zip from the directory of files called ccat-1.1.0 as follows.

However, the above method is absolutely insecure, because here the password is provided as clear-text on the command line. Secondly, it will also be stored in the history file (e.g

.bash_history for bash), meaning another user with access to your account (more especially root user) will easily see the password.

Therefore, try to always use the -e flag, it shows a prompt allowing you to enter a hidden password as shown.

How to Unzip Password Protected ZIP in Linux

To unzip and decrypt the content of the archive file called ccat-command.zip, use the unzip program and provide the password you entered above.

How to Create Password Protected ZIP File in Linux

An anonymous reader asked, «Why people want to create a zip password in Linux?». Well creating a password protected zip file is common these days especially if you are sending a confidential file or folder along the way. A zipped file with password will only be accessed by those whom you provide the password and this way it stays secure. While Linux is an Open source OS; it is considered most powerful and protected one as well. So, in this article I will be guiding through the process of creating an encrypted zip file while using Linux in two different ways.

[GUI Method] Create Password Protected ZIP File in Linux

Creating zip password in Linux using GUI method is pretty easy and it works great in these terms. Here’s what you can do to create protected zip file using Linux GUI:

Step 1: Choose Files and Folders and «Right Click» and then click on»Compress».

Step 2: Now choose .zip format from drop down menu in front of name file and Click on «Other Options».

Step 3: You’ll have option to Enter Password to encrypt .zip file with. Enter your password and click on «Create».

Step 4: Depending on your systems specification and size of files; a protected zip will be created within few seconds or minutes.

Congrats, you just created your first Linux zip with password using graphical user interface on Linux that no one can access without knowing its code.

[Command Line Method] Create password protect zip file in Linux

There are many things that comes in mind when we are choosing to protect a zip using Linux command line/terminal. You could be protecting it from your friends, colleges or securing it from anyone else accessing the files inside zip file. Okay, so now that we have an idea why you might be protecting your zip file let’s see how you can achieve it. First of all, you’ll have to install zip support and make sure it is working. Here’s step by step guide to do it.

Use This Command to Install Zip support in your Linux based system: sudo apt install zip unzip

Now that you have installed zip support into your system let’s see how you can zip a file before proceeding to protecting it:
zip -r output_file_name.zip file_name folder_name

Note: The -r option is used to recursively look into directories.

The above command will create a zip file in you with the name you given it. Now, let’s see how to password protect a zip file in Linux operating system. The method is quite similar as creating zip folder in Linux. The only difference is we also use option -e option that is for encryption purpose:
zip -re output_file_name.zip file_name folder_name

After entering above command once you hit the Return button; You’ll be asked to enter and verify the password. You will not be able to see the password; it’s Linux protocol there’s nothing wrong; just make sure you remember it. After entering password press enter and verify it again.

Other Tips: How to Unlock Password Protected ZIP in Windows

Now you know about two methods of creating a zip with password in Linux, you will be creating a lot of them depending on your need. In case you forget password of zip file that you’ve created, and it has important data inside and you need them immediately. This is where PassFab for ZIP comes in; it is a third-party software that offers 100% success rate. It recovers your password without losing a single bit of it. It uses multiple decryption technique that it can even decrypt AES algorithm protected file as well. PassFab for ZIP is using three major techniques for breaking password that offers optimal result. These techniques are:

• Brute-force Attack: Try all possible combinations, which takes more time.
• Brute-force with Mask Attack: Customize numbers, symbols, characters, etc.
• Dictionary Attack: Quickly find the password from inbuilt or customized dictionary.

If you don’t have an idea of how you can use it. Here is the guide to help you step by step during the process:

Step 1. Download and install PassFab for ZIP from its official site.

Step 2. Run the PassFab for ZIP and all options will be displayed in front of you.

Step 3. Now import the password protected ZIP file by clicking «‘Add’ button.

Step 4. Once successfully imported select the one of the three attack options:

1. Choose «Brute Force Attack» if you can’t remember a single word of your password. It will try all possible combination of password.

2. Choose «Brute Force with Mass Attack’ if you have some clue about your password. It will pop multiple options. Select that are relevant to your lost password and click «OK’.

3. Choose «Dictionary Attack» if you have password dictionary with you. This will frequently recover your lost password. Add the dictionary and click «OK’.

Note: if you choose dictionary attack there might be a message «Upgrading the Dictionary Library». Don’t worry it will take some time to complete.

Step 5. After setting all the details to PassFab for ZIP, click «Start» button and let the program recover password for you.

Step 6. Once the program exits successfully, a success diagonal along with the password will appear.

How to Create a Password Protected Zip File in Linux

Last updated October 29, 2020 By Abhishek Prakash 13 Comments

Brief: This simple tutorial shows you how to create a password protected zip file in Linux both in command line and graphical way.

We have seen how to password protect folders in Ubuntu earlier. We have also seen encrypted text editor for Linux. Today, we’ll see how to create password protected zipped files in Linux, in both command line and graphical way.

I am using Ubuntu in this tutorial but you can use any Linux distribution that uses Nautilus (now called Files) file manager for the graphical part. Command line steps are the same for any Linux distribution.

There are several ways you can encrypt zip file in Linux. In fact, there are dedicated command line tools for this task, but I am not going to talk about those. I am going to show you how to password protect a zip file without installing a dedicated tool.

Create password protect zip file in Linux [Command Line Method]

First thing first, make sure that you have zip support enabled in your Linux system. Use your distribution’s package manager and try to install it. If its not installed already, it will be installed.

In Debian/Ubuntu, you can use this command:

Now, let’s see how to password protect a zip file in Linux. The method is almost the same as creating zip folder in Linux. The only difference is the use of option -e for encryption.

The -r option is used to recursively look into directories. The -e option is for encryption.

You’ll be asked to enter and verify the password. You won’t see the password being typed on the screen, that’s normal. Just type the password and press enter both times.

Here’s what the process looks like on the screen:

zip -re my_zip_folder.zip agatha.txt cpluplus.cpp test_dir
Enter password:
Verify password:
adding: agatha.txt (deflated 41%)
adding: cpluplus.cpp (deflated 4%)
adding: test_dir/ (stored 0%)
adding: test_dir/myzip1.zip (stored 0%)
adding: test_dir/myzip2.zip (stored 0%)
adding: test_dir/c.xyz (stored 0%)

Do note that if someone tries to unzip this file, he/she can see the content of the folder such as which files are there in the zipped file. But the files cannot be read.

If you are using Ubuntu 16.04 with Unity desktop environment, things will be slightly different. Click on the next section to see the steps for Unity desktop.

To follow this tutorial, you just need to make sure that you are using Nautilus/Files file explorer. If you are using Fedora, Ubuntu Unity, or any other Linux distribution with GNOME as its desktop environment, you have Nautilus.

Step 1

Right click on file(s) and/or folder(s) and click on Compress:

Select the compression format you want to choose. There are several formats available but you cannot use all of them for password protecting the files.

Step 2

I advise to use the .zip format. After selecting the compression format, click on the Other Options.

Step 3

You’ll see option of entering password in Other Options. If the compression format you selected doesn’t support encryption, this Password area would be greyed out.

It may also happen that you’ll have to install the compression utility to use the encryption. For example, if you do not have RAR installed, password option will not be available.

Step 4

Enter a suitable password and click on Create:

Compression takes time based on the size of the file or directory. You’ll see a message like this when the files are compressed successfully:

The compressed file thus created is password protected. If you try to extract it, it will ask you to enter the password:

As you can see, no one (in normal ways) can extract this file without the password. Congratulations, you just learned how to encrypt zip files in Ubuntu Linux.

Just for your information, double clicking on the password protected directory might give the impression that you may access the encrypted directory without a password, but you cannot actually read those files.

I hope this quick tutorial helped you to create password protected zip files in Linux. In coming days, we shall see how to password protect a directory in Linux and how to break the encryption. Stay tuned 🙂
