`A part of the script above doesnt works:
...
$fp=fopen("/path/to/private.key","r");
$priv_key=fread($fp,8192);
fclose($fp);
// $passphrase is required if your key is encoded (suggested)
$res = openssl_get_privatekey($priv_key,$passphrase);
...
This should works:
// $passphrase is required if your key is encoded (suggested)
$res = openssl_get_privatekey("file:///path/to/private.key",$passphrase);`

`Encrypt using private key, decrypt using public key.
Use this for posting signed messages: Anyone with access to
your public key can read it, but they can't create one with
your signature.
<?php

$priv_key=fread($fp,8192);
fclose($fp);
// $passphrase is required if your key is encoded (suggested)

/*
* NOTE: Here you use the returned resource value
*/
