Thank you for the information.
I'll take a look and yes, it is a Windows platform.

You neglect to cite your platform. I seem to remember you're a Windows
user, however.
GPG would do it. Problem is, it's potentially a lot easier to do it
"correctly" on Windows in the sense of piping the passphrase to a file
descriptor via USER than it is to do it on Windows. You can encrypt
without using a passphrase if you configure it properly, but you need to
supply a passphrase to decrypt, period.
In *nix, you can pipe that information in on GPG's STDIN channel. On
Windows, fP doesn't have USER, so you'd have to do something lame like put
it in a batch file, which makes it that much easier to peel open, since if
you can embed it in fP's processing table and have it encrypted (-not-
ABE=ASCII), then at least the passphrase is tucked away somewhere
"moderately" safe.
There are some front-ends to GPG for Windows that may help with this sort
of thing, as I recall. You should try Google and take it from there.
