Ask post: What is on your USB memory stick?

What program do you use to encrypt your data? My USB stick came with a little encryption program I deleted because it was PC-only, and I use my flash drive to move data (work project files and information) between a WinXP PC at work and a PowerBook at home, so I'd need something cross-platform or I'd need a program for each platform. I'd be interested in recommendations.
