Hi, I want to encrypt my pen drive. Are there any open source or freeware programs that I can use to do this? Being able to decrypt it on any computer running XP without installing any software would be nice. Thanks in advance.

Thanks. Also, I like that google link you posted googleit :)

I absolutely LOVE TrueCrypt! It does exactly what I want it to do. I can just partition my pen drive and put TrueCrypt on one partition (and have another encrypted partition) to use this on other computers. It does more than encrypt whole drives; you can make little files that you can have it mount as disks. Then you can put stuff in them. Thanks!

I second TrueCrypt! Best open source encrypt program for flash drives out there. I have it being used on all 8 of my drives.
