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
