Windows only: Free application Eraser Portable puts previously mentioned Eraser—the popular open-source secure file deletion tool—on your thumb drive for secure file deletion on the go. Like the original, Eraser Portable can wipe any hard drive, optical media, files, folders, encrypted data, the Recycle Bin, and pretty much any other data you want to kill. It may not be an app you use every day, but it's a great utility to throw on your thumb drive, iPod, or other portable device for those times you do need a quick, secure delete.
