Securing a USB stick

USB sticks, we all put our vital information on it as they're extremely handy to take with you. Downside is that because they're so small, there's a tendency to lose them. Making sure others can't read your private information in case you lose it is a must for most people (like me). Therefor I had a look into encryption techniques:

Truecrypt
Truecrypt is a well known free encryption program, that features a portable mode for USB sticks. This will autorun the truecrypt program and after supplying the password will mount your USB stick on a driveletter of your choosing. Regrettably you have to be an administrator on the machine for this too work.

Omziff
Another program which almost does the same is Omziff. This is also a free portable program that can encrypt files, and can also split files or secure erase them. Download link to the latest version: Omziff 3.3 download. For Omziff you don't need to be an administrator, so you can take your stick anywhere and it will work (as long as it's a windows machine, and your company security isn't done by a paranoid IT guy).

BitlockerToGo
Since Windows Vista, Microsoft has introduced the Bitlocker technology by which you can encrypt drives. New in Windows 7 is BitlockerToGo which, like Truecrypt, can encrypt your drive and include a mounting tool in the unencrypted part of the drive. This will then automatically ask for a password upon insertion of the stick in any PC with Windows 7. As the guys from www.windowssecurity.com made an excellent video on how to set this up, i don't have to reinvent the wheel: Videolink.

Of course there will be many other tools to do the same as the aforementioned programs. But the ones I discussed in the article should give you a good head start on how to make sure nobody sees what's on your usb stick.
