Mac Encryption using Disk utility

This tutorial shows you how to use encrypted disk images in MacOS X to transfer files securely, and to store files on your mac in a secure manner. This tip entirely uses just built-in components of a regular MacOS X install, no need to get any additional software.

Hey Ken, that was neat. I’ve made a couple of sparse image disks for keeping my private stuff.
Thanks a ton!

Thanks! I forgot the actual procedure!

Hi Ken,
Several months ago I created a sparseimage using this technique, and must have hid it in the library folder, and probably renamed it ( yes I know, very sensitive info, and very paranoid 🙂 ). the problem now, I forgot how this file look like, any suggestions how to find it, spotlight doesn’t look into the library folder.
Thanks a lot.

Hi Ken,
I’m wondering how I can share encrypted disk images over the internet with someone or how to encrypt a single file with Mac OS X and then share. Thanks!

Just follow my instructions to encrypt the disk image, when you have finished copying your files in, “eject” the image and send the .dmg or .sparseimage to your recipient via email or whatever method you wish to.

For the gentleman who forgot where he put his disk image: the Terminal command

sudo find ~/Library -name “*.dmg” -print

is your friend. (using sudo will prevent complaints about not being able to access certain files and directories that it will encounter in its search).
