A file descriptor is something like a stream or pipe. Applications which
communicate with gpg use --passphrase-fd to give gpg the passphrase. If
you use --passphrase-fd 0, it will read it from standard in. Apart from
that... <http://en.wikipedia.org/wiki/File_descriptor> explains it in
more detail.

You could of course use --passphrase-file <file>, provided the file is
only readable by yourself, but on a MinGW32 platform this is quite
unlikely. That leaves --passphrase-string, which is still a security risk.
