title: Is RC4-128 bit secure than AES-128 bit?
body: <p>I have a client-server system. The client and the server application are programmed in windows. I use <code>Windows Crypto API</code> for encrypting communication between client and server. My selected details for encrypting data are:</p>
  
  <p>Provider : <code>Microsoft Enhanced Cryptographic Provider v1.0</code></p>
  
  <p>Provider Type : <code>PROV_RSA_FULL</code> - Exchange Key: <code>RSA</code></p>
  
  <p>Algorithm : <code>RC4 stream encryption - 128 bit</code></p>
  
  <p>I ask are my selections for encrypting secure? How much are they secure? Can you compare my specifications with <code>AES 128 bit</code>?</p>
