Automate ‘passworded’ zip archiving of a selected file in Macintosh Finder

Surprisingly it’s a pain in the posterior to (zip) archive a file on MacOS with a password from the desktop.

Below is an Applescript that uses the MacScript.com library (available here) that automates the creation of a password protected zip archive of the currently selected file in MacOS Finder. Even better, the attached Automator Service Script containing this Applecript can be downloaded and double clicked to install a service called ‘Archive with password’ onto the Finder’s contextual menu (mouse right click). Whichever file is currently selected in the Finder can be archived with a preset password or the password can be changed in the dialog box that appears during runtime.

Edit this Applescript in Script Editor to change the default password and then drop it into your Fastscripts Apple Menu for easy access. Alternatively you can create an Automator Service where the Service receives selected files or folders in Finder and which runs an Applescript, and then add the contents of the script below (with a little modification noted with ‘*’ below) into the Automator Script and save it. Then double click this Automator Script in the Finder to install it into your system. (If none of that makes sense then download the automator workflow script below.

Don’t forget to download the Macscript.com library file into your User/Library/Scripting Additions folder or somewhere sensible and reference the location to load the library. For User/Library/Scripting Additions folder Select the Go menu in the Finder with the option key held down to first access the User Library folder). Once you start using the MacScript.com Library, you’ll find Applescript will be so much simpler easier and more functional.

Run the Applescript from the Fastscripts menu
