title: Programmatically encrypting a config-file in .NET
body: <p>Could somebody please do a rundown of how to programmatically encrypt a config-file in .NET, preferably in C#.</p>
  
  <p>What I would like to do is do some kind of check on an application's startup to see if a section is unprotected, and if it is, then encrypt it. This for both settings and connection-strings.</p>
  
  <p>Also if anyone could list the types of encryption-providers and what is the difference between them.</p>
  
  <p>I don't know if the code for doing this in a normal WinForms-application is transparent to doing this in ASP.NET.</p>
