Thanks, I understand how it works now. The only thing I've got working
on Windows is to use a file containing the passphrase. The script could
create a temporary file, but I don't feel too pleased about having a
password stored in a file at all. I guess one could encrypt the temp
file before it's written. This is it in Perl:

system "gpg.exe -o $file.gpg --passphrase-fd 0 -c $file < pass.txt";

Windows will only accept a file as input, grrr. Does anybody know how
to pass the input from stdin?

The only workaround I can think of is to

I'll take a peek.

Yes please.

Thanks,
