How To: Encrypt Zip File Mac X

How To: Encrypt Zip File Mac X

ZIP files are the most popular form of file compression on the Internet. You typically create a ZIP file to compact a file(s) so that it is smaller to send to someone, typically in emails. However, any zip file can be intercepted, unzipped, and the contents be made available to the public. Luckily, Mac X has a hidden feature to secure ZIP files.

 

Mac X allows you to encrypt and password protect any zip file using Mac X Terminal. To encrypt a ZIP file inside a folder, follow these steps.

 

    1. Open Terminal (Applications -> Utilities -> Terminal)
    2. We will use the zip command in Terminal. Type zip –e (encrypt option) NAME.zip (zip file name to create) folder path to zip.

Example Sytnax:

zip -er NEW.zip /Users/kos/Desktop/test

  1. Hit enter. Now, you will be prompted to enter and confirm a password for the ZIP file. Whoever you intend to open this ZIP, they will need to know this password you set.
  2. The ZIP compression will begin. ZIP compression time depends on the size of your files.
  3. Once completed, the Terminal command prompt will be back to $
  4. By default, your newly encrypted zip file will be located: HardDrive/Users/user/yourzipfile.zip
