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.

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