NET MVC 5 has some great improvements around authentication.This includes new Authentication filters, new Authentication options and ASP.NET Identity Management.In this article, we will take a look at the new authentication filters and how you can use these filters to make authentication decisions.At this stage, ASP.NET MVC does not provide any built in authentication filters.However it provides you with the framework, so you can easily create your own custom authentication filters.If you have used ASP.NET MVC before, you probably have used Authorization.Filters. Authorization filters allow you to perform authorization tasks for an authenticated user.A good example is Role based authorization.ASP. NET MVC 4 also introduced a built in Allow.Anonymous attribute.This attribute allows anonymous users to access certain ControllersActions.This way, you can protect the entire site by using this Authorize attribute and then use the Allow.Anonymous attribute, to allow anonymous users to access certain Actions and Controllers.If you would like to read more on Allow.Anonymous attribute, heres a good article http blogs.New authentication filters run prior to authorization filters.It is also worth noting that these filters are the very first filters to run before any other filters get executed.This article is published from the Dot.Net.

We will first create a new ASP.NET MVC 5 application.Once you have installed Visual Studio 2.File New Project, under templates CVB select Web, and then select ASP.NET Web application.A dialogue box will pop up.Select MVC from the template.Then simply click on Create Project.In order to create an Authentication filter, you must implement the IAuthentication.Filter. Below is the implementation of ASP.NET MVCs IAuthentication.Filter. public interface IAuthentication.Filtervoid On. AuthenticationAuthentication.Context filter. Context void On.Authentication. ChallengeAuthentication.Challenge. Context filter.Context As I mentioned earlier, to be able to use these filters as your standard Action Filters, you also need to derive from Action.Filter. Attribute.This allows you to decorate your Authentication filter in Controllers, Actions or use as a Global filter.Custom. Authentication.Attribute Action.Filter. Attribute, IAuthentication.Filterpublic void On.AuthenticationAuthentication.Context filter. Context public void On.Authentication. ChallengeAuthentication.Challenge. Context filter.Context If you look at the above Custom.Authentication. Attribute, there are two interesting methods required to implement.On. Authentication b.On. Authentication.Challenge. Lets take a look at these two methods in detail.On. Authentication.During Action invocation, ASP.NET MVC invokes Authentication Filters by calling the following method Authentication.Context authentication.Context Invoke. Authentication.Filterscontroller.Context, filter. Info.Authentication. Filters, action.Descriptor This method creates an Authentication.Context using the original principal, and executes each filters On.Authentication method.Please see the following code Authentication.Context context new Authentication.Contextcontroller.Context, action. Descriptor, original.Principal foreach IAuthentication.Filter filter in filtersfilter.On. Authenticationcontext Authentication.Context provides you information for performing authentication.You can use this information to make authentication decisions based on the current context.For example, you may decide to modify the Action.Result to different result type based on the authentication context, or you may decide to change the current principal based on the authentication context etc.If you change the users current principal to use a new custom principal, the ASP.NET MVC framework will set a new principal as shown here IPrincipal new.Principal context.Principal if new.Principal original.PrincipalContract.Assertcontext. Http.Context null context.Http. Context. User new.Principal Thread.Current. Principal new.Principal On. Authentication.Challenge. On. Authentication.Challenge method runs after the On.Authentication method.You can use On. Authentication.Challenge method to perform additional tasks on the request.Authentication. Challenge.Context Invoke. Authentication.Filters. ChallengeController.Context controller.Context, IList filters,Action.Descriptor action.Descriptor, Action.Result resultSimilar to Authentication.Context, this method also creates an Authentication.Challenge. Context as shown here.Then it invokes the On.Authentication. Challenge method per Authentication.Filter. Authentication.Challenge. Context context new Authentication.Challenge. Contextcontroller.Context,action. Descriptor, result foreach IAuthentication.Filter filter in filtersfilter.On. Authentication.Challengecontext The key thing to remember is that On.Authentication. Challenge does not necessarily run before every other Action Filter.It can run at various stages.For example, it can run after Authorization.Filters or it can run after Action execution completed so on.Since this is at various stages, you now have the ability to change the action result based on the authentication.As I mentioned earlier, you can use the On.Authentication. Challenge method to modify the Action.Result. filter. Context.Result new Http. Unauthorized. Licensed Structural Engineer In Hyderabad Jobs . Result Implementing and configuring your custom Authentication Filter.We will use the Custom.Authentication. Attribute we just created and implement both On.Authentication and On.Authentication. Challenge methods.We will then configure it to execute only for Home.Controllers Index action.In On. Authentication we set the current principal to a custom principal with some additional properties.In On. Authentication.Challenge we check whether the user is authenticated or not and modify the Action.Result to an Http.Un. Authorized. Result.Custom.
