Last cosmetics and PHP/LSL test scripts

Browse Source 
All is working fine :)

The following script send a request to the PHP file where the encrypted  string using osAESEncrypt() is decrypted and re-encrypted using the PHP openssl_XXXX. the return is the original string and the re-encrypted separated by "|"... the script decrypt the returned re-encrypted using osAESDecrypt() and log it in the chat.

LSL script:
<pre><code>
// Change the url to point to your PHP file.
string url =  "http://127.0.0.1/aesTest.php";
string plainText = "Hello World :)";
string secret = "#!qUeRtY$@123^456€!#";
key r_id;

default
{
    touch_start(integer i)
    {
        string encryptedText = osAESEncrypt(secret, plainText);
        llOwnerSay("\nEncrypted with osAESEncrypt:\n"+ encryptedText);

        r_id = llHTTPRequest(url, [HTTP_METHOD,"POST",HTTP_MIMETYPE,"application/x-www-form-urlencoded",HTTP_BODY_MAXLENGTH,"16384"], "data="+ encryptedText);
    }

    http_response(key id, integer status, list metaData, string Response){
        if(status = 200 ){
            if(id == r_id){
                if(Response != ""){
                    list temp = llParseString2List(Response,"|",[]);
                    llOwnerSay("\nDecrypted using PHP openssl_decrypt:\n"+ llList2String(temp,0));
                    llOwnerSay("\nEncrypted using PHP openssl_encrypt:\n"+ llList2String(temp,1));
                    string decryptedText = osAESDecrypt(secret, llList2String(temp,1));
                    llOwnerSay("\nDecrypted with osAESDecrypt from PHP:\n"+ decryptedText);
                }
                else{
                    llOwnerSay("Enc/Dec Failed! Response:\n"+ Response);
                }
            }
        }
        else{
             llOwnerSay("Destination not available.\nstatus: "+ status);
        }
    }
}
</code></pre>

The PHP file:
<pre><code>
<?php
    if(getenv('REQUEST_METHOD') == 'POST') {
	    $script_data = file_get_contents("php://input");
        if($script_data){
            $data = $_POST['data'];
            $secret = "#!qUeRtY$@123^456€!#";
            $key = hex2bin(strtoupper(hash('sha256', $secret)));
            $iv = hex2bin(strtoupper(explode(":", $data)[0]));
            $encryptedText = hex2bin(strtoupper(explode(":", $data)[1]));
            $plainText = openssl_decrypt($encryptedText, "AES-256-CBC", $key, $options=OPENSSL_RAW_DATA, $iv);
            $retIv = openssl_random_pseudo_bytes(16);
            $reEncrypted = openssl_encrypt($plainText, "AES-256-CBC", $key, $options=OPENSSL_RAW_DATA, $retIv);

            echo $plainText && $reEncrypted ? $plainText."|".bin2hex($retIv).":".bin2hex($reEncrypted) : "";

        }
    };
?>
