JWT (JSON Web Token)

Hi developer,

I have learned about token authentication as below:
http://bitoftech.net/2014/06/01/token-based-authentication-asp-net-web-api-2-owin-asp-net-identity/
http://bitoftech.net/2014/10/27/json-web-token-asp-net-web-api-2-jwt-owin-authorization-server/
http://www.developerhandbook.com/c-sharp/create-restful-api-authentication-using-web-api-jwt/

These are using it with old version as Asp.net 4 but I want JWT using ASP.NET 5.
Is there any sample of JWT using ASP.Net 5?

I am waiting for your response.
Thanks in Advance!
