Create an Encrypted Zip File on MacOS

This guide will quickly walk you through how to create an encrypted ,zip file on a Mac. Since MacOS and Linux systems have a lot in common, this will likely work on any Linux distributions too.

  1. Move the files you want to compress and encrypt to your Desktop.
  2. Open Terminal by pressing CMD + SPACE and searching for Terminal in the search window that pops up.
  3. Run the following command to zip and encrypt the selected files:

    zip -e ~/Desktop/zip-file.zip ~/Desktop/secret.txt
    
  4. Enter a password to encrypt your .zip file with.

  5. Enter the password again to make sure it’s correct.

  6. The zip application will compress your file(s) into a .zip and encrypt it at the same time.

It’s a good idea to delete the raw file(s) now so no-one can access them without using the password. To do this enter the following into the terminal: rm -rf secret.txt where secret.txt is the name of your file. If you have more than one, simply add on the names of the file like this: rm -rf secret.txt secret_two.jpg third_file.docx something-else.mp3.

Happy coding.
