It wasn’t long ago when TrueCrypt was the most popular encryption tool out there.  Since its demise a couple years ago, people have been scrambling to find a replacement.  For those that use Mac’s – you’re in luck.  The Mac operating system comes with the ability to create an Encrypted File Container without the need for third-party software.  All you need to do is go into the Disk Utility tool and create a “New Image”.  When you create a new image, simply name the file, select Mac OS Extended (Journaled) as your file system, and choose your encryption.   Natively, you will be able to select either 128-bit or 256 bit AES encryption.  Obviously, 128 will be faster to create but 256 will be more secure.
