title: Encrypt a single key in the appsettings section of App.Config file
body: <p>Is it possible to encrypt a single value or must you encrypt entire sections?</p>
  
  <p>I.e. Given the app.config below can how can I encrypt just the password. I've read articles on encrypting connection string sections and whole sections of app.config. </p>
  
  <pre><code>&lt;?xml version="1.0"?&gt;
  &lt;configuration&gt;
  &lt;appSettings&gt;
  &lt;add key="Interval" value="40000" /&gt;
  &lt;add key="User" value="User1" /&gt;
  &lt;add key="Password" value="boombox" /&gt;    ...
  </code></pre>
  
  <p>If you have any suggestions they would be greatly appreciated</p>
