There is a lot of software out nowadays that will allow you to encrypt files, but which one do you use? The next question is when you pick one, can you decrypt your file using different software or are you forced to use the program you encrypted your files with? I tried out quite a few in the past week and I was not super impressed by any. The way I’m going to explain how to do this comes standard in OSX and I feel will work the best for most if not all users. The main reason behind this is because out of all the programs I tried in the past week none of them allowed you to open encrypted files using other software. I found that most of these software companies were unknown and/or did not really stand out much. Example, you encrypt a file using software found online. You go back to that file months down the road after reinstalling your system from a hard drive failure or setting up new computer you go to open that encrypted file, and can’t remember the name of the program that was used to encrypt it. Or when you go to download it again you find that the website has been closed and the developer is no longer maintaining this piece of software. With no way to open your encrypted file the data inside becomes useless. My reason for using Disk utility on your Mac. As along as Apple is making computers you know you will always be able to open your file and with 128 and 256 AES encryption you should never need to worry about having your files seen. So lets get started with the how to:

  • Open Disk Utility
  • Click the New Image button
  • Enter a name in the Save As field.
  • Change the save destination
  • Select a size for your image
  • Choose a volume format “I use the default Mac OS X Extended Journaled”
  • Choose an image format
  • Choose between 128-bit AES (and/or 256-bit AES
  • Click the Create button
  • Enter a good password “Don’t save this in your keychain”
  • Click Ok

You can move files to or from an encrypted disk image as easily as you can from a non-encrypted disk image. It’s really that easy.
