How to Create a Password Protected Zip File in Linux | Secure Your Files Easily

Need to **secure your files on Linux with a password**? In this quick and easy tutorial, you'll learn **how to create a password-protected ZIP file in Linux** using the command line. Whether you're backing up sensitive documents, sharing private files, or just adding an extra layer of security, this guide has you covered.

We'll walk through step-by-step commands using tools like `zip`, `7z`, and `gpg` so you can choose the method that best fits your needs.

**What You’ll Learn:**

* How to install and use the `zip` command with password protection
* How to use `7zip` (7z) for stronger encryption
* Alternative: Encrypting with `gpg` for enhanced security
* Extracting and accessing protected ZIP files
* Best practices for secure file compression

**Method 1: Using `zip` (basic password protection)**

```bash
sudo apt install zip unzip # install if not already
zip -e secure.zip file1 file2
# You'll be prompted to enter a password
```

**Method 2: Using `7z` (AES-256 encryption)**

```bash
sudo apt install p7zip-full
7z a -p -mhe=on secure.7z file1 file2
# -p prompts for password, -mhe=on hides file names until decrypted
```

**Method 3: Using GPG for file encryption**

```bash
gpg -c file.txt
# This creates file.txt.gpg, a securely encrypted version
```

**To Extract Protected Files:**

* `unzip secure.zip` (will ask for password)
* `7z x secure.7z`
* `gpg -d file.txt.gpg - file.txt`

**When to Use This:**

* Sharing confidential documents via email
* Backing up personal or financial records
* Adding a security layer to cloud uploads
* Protecting config files or API keys

**Tips for Better Security:**

* Use 7z or GPG for stronger encryption than standard ZIP
* Never store passwords in plain text
* Always test your encrypted files before sharing

Works on:

* Ubuntu
* Debian
* Fedora
* Arch
* Any Linux distro with terminal access
