A WayTo Encrypt Drive Post-Installation?

[johnsmoke]

I was wondering if there is any way to encrypt my hard drive AFTER Ubuntu has been installed? I've had Ubuntu 11.04 for months now and would like to encrypt my drive for security and so no one else can access my data in case my computer is stolen etc.... is there any way to encrypt the drive post-installation?

On my old laptop, I hadn't encrypted my /home partition. To encrypt it after installation, I followed the instructions here: http://blog.dustinkirkland.com/2009/...directory.html
