Ich versuche, eine sichere RSA-Verbindung zwischen dem PHP-Server und dem Unity 3D-Spiel (im Web Player) herzustellen. Am Ende des Prozesses gibt $ rsa-> decrypt () "false" zurück: -

Server generiert RSA-Schlüssel und sendet öffentlichen Schlüssel an Unity:

$rsa = new Crypt_RSA();
$rsa->setEncryptionMode(CRYPT_RSA_ENCRYPTION_PKCS1);
$rsa->setPrivateKeyFormat(CRYPT_RSA_PRIVATE_FORMAT_PKCS1);
$rsa->setPublicKeyFormat(CRYPT_RSA_PUBLIC_FORMAT_PKCS1);

$keys = $rsa->createKey(512);
extract($keys);
$rsa->loadKey($publickey);
$_SESSION["privatekey"] = $privatekey;

$this->payload->Modulus = base64_encode($rsa->modulus);
$this->payload->Exponent = base64_encode($rsa->publicExponent);

Dies generiert JSON:

{"Modulus":"MTE5MjcyOTYyNjQzMTIzODQ1MTI4MjE2ODA3OTY2MDE5MDQwODQ1NTc0MDIzMDI0NDQ5MjAzMDY4NDgxNTkyNzk5MTc0MzYxMzI4MDA3Njk0MjI4NjAyMzAwODA4MDI5MzkwOTk2MjUyMTg5OTkwNDgwNzg3MDcwMjk4MjkxMjcxNjQ1NzMzNDg0MTcxNTc0MDM3ODM0NjE3ODE=","Exponent":"NjU1Mzc="}

Unity ENCODER:

var N = JSON.Parse (generatedJSON); //im using SimpleJSON library
var publicKey = new RSAParameters ();
publicKey.Modulus = Convert.FromBase64String(N ["Modulus"].Value);
publicKey.Exponent = Convert.FromBase64String(N ["Exponent"].Value);

var csp = new RSACryptoServiceProvider(512);
csp.ImportParameters(publicKey);
var plainTextData = "Hello Wordl"; //here come AES key generator (not implemented yet)
var bytesPlainTextData = System.Text.Encoding.Unicode.GetBytes(plainTextData);
var bytesCypherText = csp.Encrypt(bytesPlainTextData, false);
var cypherText = Convert.ToBase64String(bytesCypherText);

Und Server DECODER:

$rsa = new Crypt_RSA();
$rsa->setEncryptionMode(CRYPT_RSA_ENCRYPTION_PKCS1);
$rsa->setPrivateKeyFormat(CRYPT_RSA_PRIVATE_FORMAT_PKCS1);
$rsa->setPublicKeyFormat(CRYPT_RSA_PUBLIC_FORMAT_PKCS1);

$rsa->loadKey($_SESSION["privatekey"]);
$message = $_POST["unityResponse"];
$ciphertext = base64_decode($message);

$this->payload->message = $rsa->decrypt($ciphertext);

Return "Entschlüsselungsfehler in ...":

Ich denke, allgemeines Problem ist in C # ... Kannst du mir helfen?
