Hi,

I have used this code to feed data to gpg and read back the encrypted
result, Im sure you can adapt it to your needs.

function Encrypt($data){
	
	# http://www.theoslogic.com/scripts/php-gpg/
	
	$gpg_command="/usr/bin/gpg $parameters";
	
	$errLog = "/tmp/errors.log";
	
	$dspecs = array(
		0=>array("pipe", "r"),
		1=>array("pipe", "w"),
		2=>array("file", $errLog, "a")
	);
	
	$encrypted="";
	$procdata="";
	
	$gpgproc = proc_open($gpg_command, $dspecs, $pipes);
	
	if (is_resource($gpgproc)) {
		fwrite($pipes[0], $data);
		fclose($pipes[0]);
		
		while($procdata = fgets($pipes[1], 1024)) {
			$encrypted .= $procdata;
		}
		fclose($pipes[1]);
	}
	
	return $encrypted;
}

It works really well.

Regards

Ian
