title: How to decode JWT Token?
body: <p>I don't understand how this library works. Could you help me please ?</p>
  
  <p>Here is my simple code :</p>
  
  <pre><code>public void TestJwtSecurityTokenHandler()
      {
          var stream =
              "eyJhbGciOiJSUzI1NiJ9.eyJpc3MiOiJJU1MiLCJzY29wZSI6Imh0dHBzOi8vbGFyaW0uZG5zY2UuZG91YW5lL2NpZWxzZXJ2aWNlL3dzIiwiYXVkIjoiaHR0cHM6Ly9kb3VhbmUuZmluYW5jZXMuZ291di5mci9vYXV0aDIvdjEiLCJpYXQiOiJcL0RhdGUoMTQ2ODM2MjU5Mzc4NClcLyJ9";
          var handler = new JwtSecurityTokenHandler();
  
          var jsonToken = handler.ReadToken(stream);
      }
  </code></pre>
  
  <p>This is the error :</p>
  
  <blockquote>
    <p>The string needs to be in compact JSON format, which is of the form: Base64UrlEncodedHeader.Base64UrlEndcodedPayload.OPTIONAL,Base64UrlEncodedSignature'.</p>
  </blockquote>
  
  <p>If you copy the stream in <a href="https://jwt.io/#libraries-io" rel="noreferrer">jwt.io website</a>, it works fine :)</p>
