ASP.NET Core MVC Value Provider for Encrypted Route Parameter

Back in January 2013 & March 2013, I had published a detailed articles on this blog on how to create a custom Value Provider for ASP.NET MVC and ASP.NET 4.5 Model Binding respectively. In normal scenario it is not required to create custom Value Provider but sometime we require to process incoming request parameter values before default value providers feed it to model binder. For e.g. encrypted values are passed in as a query string parameter or route parameter. In such case, we can access this encrypted query string or route parameter value from within MVC action method and decrypt it there and utilize decrypted values. This is fairly straightforward for relatively small application with only a handful of MVC actions accepting encrypted values. But consider a use case where you have plenty of action methods which need to accept encrypted values either passed as a query string or route parameter. Here instead of decrypting it manually from within each and every MVC actions, we can create custom Value Provider (I’ve named it as CryptoValueProvider) to do the job. CryptoValueProvider should read encrypted query string or route parameter, decrypt it and feed plain decrypted value to default model binder so that we can get direct value in action parameter. Here in this article, we will see how to create custom CryptoValueProvider in ASP.NET Core.

C#: The request was aborted: Could not create SSL/TLS secure channel

Last month we noticed that crawler on which I worked earlier was unable to crawl some of the HTTPS websites. Crawler was built in C# and deployed on several environments running Windows Server 2012 R2. Crawler was running fine on all environments except one where it was unable to connect with few HTTPS websites and it kept raising below exception

The request was aborted: Could not create SSL/TLS secure channel.

Here in this blog post, I will explain how I troubleshot to identify root cause of this exception and its possible solution.

ASP.NET: Sharing OWIN Authentication Cookie across IIS Applications

It's been almost 3 years since I've shared my learning experience on this blog. During this past 3 years, I worked on various technology right from fixing some classic ASP pages in legacy application to ASP.NET Core, Visual Studio Team System (VSTS), Single-Sign-On (SSO) with CAS, Shibboleth, Azure AD and other related SSO technology/protocol, and much more. I'll try to post articles on some of the interesting learning experience later. But here in this post we will see how we can share OWIN authentication cookie across IIS application within same website.

[Updated] ASP.NET Web Optimization Framework & Cookieless Domain

In last week, one reader of this blog asked on twitter how to use Scripts.Render & Styles.Render with cookieless domain. Ahh wait... Still if you have not read my original post then please first read how to setup ASP.NET & MVC 4: Cookieless domain for bundling and static resources. Earlier in that post I have explained for both static & bundled resource but in that post I have used HTML Link & Script tag to serve bundled resource from static domain. Because Scripts.Render & Styles.Render generate Script & Link tag same as requested domain whereas in case of static domain Script & Link tag should not refer to requested domain but it should refer static domain. Here in this post we will see how to configure ASP.NET Web Optimization framework to use cookieless domain with Scripts.Render & Style.Render.
