title: are values in app.config safe?
body: <p>Maybe a bit of stupid question but I want to know if values that I put in the app.config for use in my application are safe? I am going to use this in an application in C#. I need it to be safe against reverse engineering or other ways of getting that key so people could read my password.</p>
  
  <p>I want to encrypt and decrypt passwords and I need a key for that. Is it safe to put the key in the app.config file?</p>
  
  <p>Example:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt;
  &lt;configuration&gt;
    &lt;appSettings&gt;
      &lt;add key="SecurityKey" value="secKey" /&gt;
    &lt;/appSettings&gt;
  </code></pre>
  
  <p>Thanks in advance!</p>
