Hi i am running a wamp server on windows 7

 

i am trying to php exec command to run a command but the output returns 1 does this mean the cmd failed to execute ?

 

$openssl_cmd = "($OPENSSL mime -sign -signer $MY_CERT_FILE -inkey $MY_KEY_FILE ".
					"-outform der -nodetach -binary <<_EOF_\n$data\n_EOF_\n) | " .
					"$OPENSSL smime"." -encrypt -des3 -binary -outform pem $PAYPAL_CERT_FILE";

sorry left some of the code out.

 

 

exec($openssl_cmd, $output, $error);


if (!$error) {
	return implode("\n",$output);
} else {
	return "ERROR: encryption failed";
}
