USB Flash Encryption software

[Journey]

I need a utility to install on 50+ USB flash drives that will protect the entire drive and all it's contents.

Does anyone know of such a utility that will do this?

Plug in --> Enter password --> Files are available.

I am really struggling to find something that can do this, it must also not need to be installed on any local hardware.

Thanks in advance for all the help!

Thanks for those, however needing admin rights after the drive is setup is no good as this cannot be done.

I really need this to be installed as a standalone .exe that can be run and has on the fly decryption and encryption. I am really struggling to find something suitable, or is there nothing that exsists like this?
