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
