title: Porting JS (or node.js, i'm now sure) aes to c# aes
body: <p>i have this JS code:</p>
  
  <pre><code>d = CryptoJS.AES.decrypt((t), CryptoJS.MD5(key), {
      mode: CryptoJS.mode.ECB,
      padding: CryptoJS.pad.Pkcs7,
      keySize: 4
  }).toString(CryptoJS.enc.Utf8);
  </code></pre>
  
  <p>I don't know how I can set <code>keySize = 4</code> in C#</p>
  
  <p>setting <code>keySize = 4</code> causing exception</p>
  
  <p>I need port JS code to C#</p>
