For several years I used TrueCrypt based encryption to secure my data. Since the release of Windows 7 and enhancements in the disk management I now see the possibility to replace TrueCrypt.
Why should I replace TrueCrypt?
The reason is simple. I am working with a managed Windows 7 client and I don’t want to load non standard software on my client. There are certain “Computer Use Policy” in place and using Bitlocker to encrypt the data is out of the box available to me.
How to encrypt a portable Bitlocker files?
Well I would create a VHD fixed disk and encrypt this virtual volume with Bitlocker to Go. Note: before you start please make sure you are running Windows 7 Enterprise or Windows 7 Ultimate version
If you are working on a Windows 7 Enterprise or Windows 7 Ultimate then Bitlocker to Go is available for you. I am not going to work with this VHD on other operating systems like OSX or Linux. If I would need to access the secured volume with non windows 7 based system I would always use a virtual machine based on Win7.
