title: NLog structuring logging masking
body: <p>Suppose we are writing the following structured log message</p>
  
  <pre><code>logger.Info("User's Password is {Password}", "1234567890");
  </code></pre>
  
  <p>I would like to mask a password property because it is a sensitive data. I found <a href="https://github.com/NLog/NLog/issues/1155" rel="nofollow noreferrer">this issue</a> but I think it is a very difficult way.</p>
  
  <p>For example, I have found <a href="https://github.com/evjenio/masking.serilog" rel="nofollow noreferrer">the extension</a> that resolves a similar task for serilog. It is very simple to use. But I didn't find any useful information for Nlog.</p>
  
  <p>How to achieve it with nlog library? 
  I will appreciate any suggestions.</p>
