I've been doing tons of research, but cannot find a good answer anywhere. I need to encrypt a USB thumbdrive with the below requirements:


- It must be compatible (able to read and write to) with both Windows and Mac OS, so it must be formatted as exFAT (correct me if I'm wrong), thus this means I cannot use the inbuilt Disk Utility that comes with Mac OS, since it doesn't allow you to encrypt exFAT 

- The Windows computer that I am planning to use it on will not allow me to install any programs on it, nor will I have administrator privileges, because it is a work computer. I looked at programs like Truecrypt, Veracrypt, Bitlocker, but while they all have the option of installing a portable version of the software on the USB thumbdrive itself, they still require some form of installation on the computer you are planning to decrypt the USB thumbdrive with. So these won't work either


Do I have no choice but to buy a pre-encrypted USB thumbdrive in exFAT format? Thanks!

FYI a Mac can also read/write FAT32 but there is a 4GB file size limit. I believe you are correct in that the only way around your problem is a self encrypted USB key as you cannot install programs on the Windows computer and the programs like Truecrypt would also needed to be installed on the Mac. 




You should contact the company regarding compatibility with a Mac.


This key looks like something you want. No installation of any program and Windows/Mac compatible.

From my point of view what you're looking for is something that works on Windows, but does not require Administrative rights.  That also works on a Mac that you control.


You have total control of the Mac, correct?  BitLocker may be the answer.  Here's a page with a link to a Mac BitLocker opener.  I haven't used it, so I can't vouch for it, but it looks like it may solve your issue.
