PGP and PHP

[Anon]

When I use this code for encrypting files I get feedback from PGP that prints in my php template and I would like to prevent the PGP feedback from printing. Open to suggestions.

class PGP{

function pgp_make($input_file){

	global $CFG;		

	putenv("PGPPATH=$CFG->pgp_path");

	$tmpToken 	= md5(uniqid(rand()));
	$plainTxt		= "$CFG->pgp_data_center" . "$tmpToken" . "data";
	$crypted		= "$CFG->pgp_data_center" . "$tmpToken" . "pgpdata" . ".asc";


	$fp = fopen($plainTxt, "w+");
	fputs($fp, $input_file);
	fclose($fp);



	system("$CFG->pgp_app -o $crypted -ta $plainTxt");

	$fd = fopen($crypted, "r");
	$mail_cont = fread($fd, filesize($crypted));
	fclose($fd);

	unlink($plainTxt);
	unlink($crypted);


	mail($CFG->email_recipient, $CFG->email_subject, $mail_cont, $CFG->mailheaders);

}
