1. Create a ZIP file:
First, create a ZIP file of the files you want to protect. To do this, open a terminal window and navigate to the directory containing the files you want to protect. Then, run the following command:
zip -r protected.zip *
This will create a ZIP file called “protected.zip” containing all the files in the current directory.
2. Set a password:
Next, set a password for the ZIP file. To do this, run the following command:
zip -e protected.zip
This will prompt you to enter and confirm a password for the ZIP file.
3. Verify the password:
Finally, verify that the password is working by trying to open the ZIP file. To do this, run the following command:
unzip protected.zip
This will prompt you to enter the password you set earlier. If the password is correct, the ZIP file will be extracted. If the password is incorrect, the ZIP file will remain encrypted.
