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

echo "Source: $source";

$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);

/*

 * NOTE:  Here you use the returned resource value

 */

openssl_private_encrypt($source,$crypttext,$res);

echo "String crypted: $crypttext";



$fp=fopen ("/path/to/certificate.crt","r");

$pub_key=fread($fp,8192);

fclose($fp);

openssl_get_publickey($pub_key);

/*

 * NOTE:  Here you use the $pub_key value (converted, I guess)

 */

openssl_public_decrypt($crypttext,$newsource,$pub_key);

echo "String decrypt : $newsource";

?>
