Anyone know how to password protect a USB flash drive?

[[][][][]]

I carry a Kingston 1GB flash drive, with some information that I would rather keep secure. It contains employee hiring info, etc. I would like to add a password to the flash drive, so your basic dumbass can't open it. Does anyone know of any good programs out there? I need it to be able to be contained on the flash drive itself, so I can open the drive on any PC. I have searched and havent had any luck.
Thanks

i don't know if this is what you are looking for but i was reading a little bit about it today at work. i'm not quite sure how it works but i figure it may be worth a try.
