Example 1: php rsa encryption
// Use phpseclib: http://phpseclib.sourceforge.net/
<?php
include('Crypt/RSA.php');
$privatekey = file_get_contents('private.key');
$rsa = new Crypt_RSA();
$rsa->loadKey($privatekey);
$plaintext = new Math_BigInteger('aaaaaa');
echo $rsa->_exponentiate($plaintext)->toBytes();
?>

<?php
$publicKey = file_get_contents("public.key");
$textToEncrypt = "My Plain Text" ;
$cipherType = "RSA/ECB/PKCS1Padding";
