title: Ktor application.conf - Jwt configuration
body: <p>I'm trying to set up <strong>JWT authentication</strong> in my ktor app. <a href="https://ktor.io/docs/jwt.html" rel="nofollow noreferrer">Documentation</a> suggests to define a jwt verifier into <code>application.conf</code> file like below:</p>
  <pre><code>jwt {
      domain = &quot;https://jwt-provider-domain/&quot;
      audience = &quot;jwt-audience&quot;
      realm = &quot;ktor sample app&quot;
  }
  </code></pre>
  <p>I'm not an expert of jwt authentication, so I was wondering what's the meaning of <code>domain</code>, <code>audience</code> and <code>realm</code> settings, documentation unfortunately lacks of these details.</p>
