Automator workflow of the month: Easily encrypt folders
You can use Apple’s Disk Utility to convert a folder into an encrypted disk image—a protected archive that you unlock with a password. Such images are particularly helpful when you’re working on confidential company documents away from the office or when your business card reads: International Person of Mystery. But the truth is that creating encrypted disk images with Disk Utility is cumbersome. Thankfully, with a simple Automator workflow, you can secure documents in an instant. It works like this:
Create the workflow
Launch Automator. In the template chooser, select Application and click Choose. Select the Files & Folders library and from its list of actions drag New Disk Image, Get Specified Finder Items, and Move Finder Items to Trash into the workflow area (in that order).
Click Options in the New Disk Image action, and enable the Show this action when the workflow runs option. Configure the Size pop-up menu in this action to read Size Disk Image to fit contents. Enable the Encrypt option. From the When done pop-up menu, choose Unmount and return the image file.
In the Get Specified Finder Items action, click Options and enable both the Ignore this action’s input and Show this action when the workflow runs options. Choose File > Save, and in the sheet that appears, name the application Encrypt Image and save it to the desktop.
