GnuPG and my CGI

Okay, I've gotten GnuPG and my cgi to work nicely together (thanks to
cgiwrap) and now my script will send me encrypted messages. The main flaw I
see in my script is that it writes the file to the disk, then it encrypts to
a new file, sends the new file and then deletes both files. I realize the
file is only there for fractions of a second, but I think it would be better
if I could just send the information straight from the script to gpg and
have the only file written to disk. I'm pretty sure this is possible, I
just haven't figured out which commands to use. Anyone have any
suggestions?

Thanks

You can use gpg as any other unix filter programm. Just use a pipe:

prog_wich_creates_data | gpg ENCRYPTION_OPTS | mail MAIL_OPTS

If you don't have a single programm which creates the data, you can group
different programms:

{
echo "something"
echo "foobar"
some_example_programm
echo "this is the last line
} | gpg ENCRYPTION_OPTS | mail MAIL_OPTS
