TrueCrypt, encryption application

The best encryption software I have found during my 12 years with computer (Since 1997)
I spent sometime (around 4 years) with safe house application called SafeDisk, it was great, enables you to create logical encrypted disks.

But now, I got this, this is the best, it enables you to put a second area with a hidden password for your encrypted volume
So that you will have two areas, one inside another to prevent showing valuable data if you were forced to give the password
