That is quite easy.
Get a small thumb drive which are now almost free.
Put on it some random data (be sure that data is not
also on your HD).
So, when you encrypt, you incorporate that data into
the encrypted file(s), then remove the thumb drive.

I was thinking about the infamous "code purple error" for HP
computers, where Windows is keyed to the hardware of the machine. If
you swap out a hard drive or change a card, it won't boot. Apparently,
there is a "tattoo" of various hardware identifiers in static memory
somewhere and the OS matches a code put in during installation with
that number.
For the HP issue, the fix is easy -- you just delete the command to
check during boot up. But, I was thinking about this as an encryption
option -- where one could encrypt files in a way that automatically
incorporates hardware information with the passphrase. That way, if
someone were to intercept a file and knew your passphrase, they would
still not be able to decrypt the file unless they did it on one
specific machine.
Is there anything like that for fedora? It would probably be pretty
easy to hack the gpg source code to add a few lines to append system
information to the passphrase, but if there's something already
around, I'd like to play with it...
