I'm not familiar with proc_open being that it is knew but yes the
idea is correct.

The $pipes parameter isn't the arguments to the script but an array
that is returned with the pipe you defiend below.

In most cases you may want your #2 stream (the error stream) to go to
a pipe back to this script. so you want
2=> array('pipe', 'r')

Pass your parameters like so:
$process = proc_open("gpg -a --encrypt ...", $descriptorspec, $pipes);

Now you can check the error stream and do some error checking:
while(!feof($pipes[2])) {
$errors .= fgets($pipes[2], 1024);
}
fclose($pipes[2]);
//... error checking stuff.

I believe you need to set some headers to tell the email program
that this message is encrypted, but I might be wrong.
