title: Constant-Time comparison
body: <p>A relatively simple question:</p>
  
  <p>It <em>appears</em> that C# doesn't come with baked-in constant-time comparison methods or extensions, why not? Sure it's a simple algorithm, but it seems so basic it should be included.</p>
  
  <p>It is typically not recommend to write any of your own crypto code, however it appears that there aren't any libraries for this kind of purpose, am I missing some? </p>
