Encrypt in C# using RSACryptoServiceProvide and decrypt using openssl_private_decrypt in PHP
<p>I spent whole day for trying to get it work but no luck:(</p>

<p>I use these code in C# for encryption:</p>

<pre><code>RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();
RSAParameters rsaParam = rsa.ExportParameters(false);
rsaParam.Modulus = Convert.FromBase64String("MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCwlhAsNcNCDRgzCc49u/0iSDrdJn7yoiH/HHipbQp0QSejzg/48mMA6wb32OPQ7qzBgJNvwiQbMvi89BvGNAJ9K8vM0RW7WOqtnb/8IK9BAJVtEwJ3vvKTf5EluiUgWVbGYpWPjbl/lsD3/hRTR0uF46h7q4OlARxOupl9xVS2wQIDAQAB");
rsa.ImportParameters(rsaParam);
string msg = "This is a test.";
byte[] encValue = rsa.Encrypt(Encoding.UTF8.GetBytes(msg), true);
Console.WriteLine(Convert.ToBase64String(encValue));
</code></pre>

<p>This is the PHP code I use to decrypt.</p>

<pre><code>// Read key
$fp = fopen($KeyPath,"r");
$Key = fread($fp,8192);
fclose($fp);
openssl_private_decrypt($data, $decrypted, openssl_get_privatekey($Key, "123456"));
</code></pre>

<p>The private key I used(Passphase "123456"):</p>

<pre><code>-----BEGIN RSA PRIVATE KEY-----

<p>I am not familiar with encryption, can some one please tell how to get it work?
PS: I think the code in php is fine since I tested the code seperately.</p>
