It would be helpful if you mentioned which operating system you are targeting.

You may find past discussions on the project's misc@ mailing list providing further insight. One such search through the archives yielded the following:

I've read the manual, but if I understood correnct, it works only when using raid. I don't use it. Maybe someone can suggest something more?

Only one device (in your case, a USB device...) is required. From bioctl(8):
Code:
         C       CRYPTO: An encrypting discipline.

             The RAID 0 and RAID 1 disciplines requires a minimum of two
             devices passed to -l, RAID 4 and RAID 5 require at least three
             devices, and the CRYPTO discipline requires exactly one.

The OpenBSD Journal published an article on encrypting the root file system in May of this year. While the goals of the author may be different from what you would like to do, the article describes using a key drive with softraid(4) and bioctl(8) with the Crypto discipline:
