Encryption is often a basic requirement for data security and the open source TrueCrypt project promises to make it as easy as possible.
Using a virtual encrypted disk, TrueCrypt can encrypt an entire partition or storage device, including USB flash drives or regular hard drives.
And since the encryption is in real-time it should be transparent to the user. It also supports hardware-accelerated encryption on modern processors.
TrueCrypt will run on Windows, Mac OS X and Linux.
