Encryption REDUX

PGP/GPG - Open source and Powerful.  Perfect for encrypting email and files.

Back in our first episode of the Mind Tech Podcast we talked about PGP/GPG.  It is the most widely used and most secure form of encryption publicly available.

It is perfect for secure email and individual files on your computer, but what if you want to take encryption to the next level and secure large directories or even entire Hard Drives?

That's where Truecrypt comes in...

Truecrypt - Open source and Powerful.  Perfect for encrypting directories, folders and entire Hard Drives

Very slick easy to use GUI - Available for Unix/Linux, Mac and Windows.

Truecrypt can create a virtual encrypted disk within a file or encrypt a partition or the entire storage device, Hard Drive or USB Thumb drive.

You can also create encrypted hidden directories or partitions, which are invisible without the truecrypt application.

You must use the truecrypt application to mount these directories / drives.  Once the directories / drives are mounted you use them as you normally would use standard directories / drives.  Once they are unmounted they encrypt and are secure.

EncFS - Open source and Powerful.  Perfect for encrypting directories, folders and Cloud Services.

Command line - Available for Unix/Linux and Mac. There is a GUI version on windows called boxcryptor.  It is compatible with EncFS, but is paid software and therefore not completely open source.

EncFS is similar in many respects to truecrypt, except it is perfectly suited for secure cloud storage.

Sure, you could use PGP/GPG to encrypt individual files and upload to your cloud service, and this would be very secure. But also a hassle.  You could also encrypt a volume using truecrypt and upload to your cloud service, but there is a major disadvantage in doing so.

Any changes made to the volume in truecrypt, the entire volume is re-encrypted and re-uploaded to your cloud service.  It all works, but is time consuming.

EncFS on the other hand does everything on the fly and only changes the files that are changed.  So all done in real time and very fast.

EncFS creates two folders or directories, one on your local drive and the other in your cloud service.  Once the local drive is mounted any changes made to that drive is automatically duplicated and encrypted in the cloud service drive.  The drive in the cloud is always encrypted and secure.
