title: encrypt data in Javascript with "RSACryptoServiceProvider" Public Key -> Exceed Maximum Exception
body: <p>I have a Instance of the "RSACryptoServiceProvider" in my backend Code.</p>
  
  <pre><code>  oRsa = new System.Security.Cryptography.RSACryptoServiceProvider(2048);
    var Key = CryptoHelper.ExportPublicKey(oRsa);
  </code></pre>
  
  <p>The Code to Export the Public Key I got from here: <a href="https://stackoverflow.com/a/28407693/579623">https://stackoverflow.com/a/28407693/579623</a> ( I also tried this <a href="https://stackoverflow.com/a/25591659/579623">https://stackoverflow.com/a/25591659/579623</a>)</p>
  
  <p>the "key" is send to my Javascript Client wich uses JSEncrypt to encrypt the Data.</p>
  
  <p>Problem now is I got the following error in my Backend: "The data to be decrypted exceeds the maximum for this modulus of 256 bytes."</p>
